National Aeronautics and Space Administration	$558.6K	2015-07-06	2019-07-06	541712	IGF::OT::IGF THE PROPOSED WORK BUILDS ON WHAT WAS LEARNED IN THE CURRENTLY FUNDEDLCLUC PROJECT (FINISHING UP IN MID-2014). THIS WORK SUGGESTS BOTH CLIMATE AND LAND-USE CHANGE PROCESSES ARE THREATENING ANDEAN WETLANDS, AND THE LIVELIHOODS DEPENDENT ON THEM. THE GOAL OF THIS PROPOSAL IS TO FURTHER CLARIFY THE RELATIVE IMPORTANCE OF THESE FACTORS (CLIMATE/PHYSICAL LANDCOVER AND SOCIOECONOMIC/LAND-USE) ON HOW THESE SYSTEMS ARE CHANGING. WE ARE RESPONDING TO ELEMENT 1 OF THE ROSES-2013 LCLUC SOLICITATION, LCLUC IN MOUNTAINOUS REGIONS. THE PROPOSED WORK BUILDS ON WHAT WE HAVE LEARNED IN OUR CURRENTLY FUNDED LCLUC PROJECT (FINISHING UP IN MID-2014). THIS WORK SUGGESTS BOTH CLIMATE AND LAND-USE CHANGE PROCESSES ARE THREATENING ANDEAN WETLANDS, AND THE LIVELIHOODS DEPENDENT ON THEM. THE GOAL OF THIS PROPOSAL IS TO FURTHER CLARIFY THE RELATIVE IMPORTANCE OF THESE FACTORS (CLIMATE/PHYSICAL LANDCOVER AND SOCIOECONOMIC/LAND-USE) ON HOW THESE SYSTEMS ARE CHANGING. WE PROPOSE TO ASSESS THEIR CURRENT REGIONAL EXTENT AND HEALTH WITH SATELLITE DATA, THEIR PAST AND FUTURE CLIMATE ENVIRONMENTS WITH CLIMATE MODELS AND MODEL OUTPUT, AND THE DRIVERS OF CURRENT LAND-USE AND LAND-USE CHANGE WITH SOCIOECONOMIC SURVEYS. WE WILL CONDUCT THIS ACROSS THE ALTIPLANO REGION EXTENDING FROM THE CORDILLERA BLANCA IN PERU TO SAJAMA IN BOLIVA. THIS WILL PROVIDE ESSENTIAL INFORMATION ON HOW THESE SYSTEMS ARE REACTING TO AND BEING ACTED UPON BY CHANGES IN CLIMATE AND LAND-USE PRESSURES. BY INTEGRATING THE RESULTS FROM THESE COMPONENTS, WE WILL BE ABLE TO SUGGEST FUTURE TRAJECTORIES FOR THESE SYSTEMS, ACROSS THE TROPICAL ANDES OF BOLIVIA AND PERU. OUR METHODS AND RESULTS MAY PROVIDE USEFUL INSIGHTS FOR ANALYSIS OF MOUNTAIN SYSTEMS ELSEWHERE.

NNH15CN67C	SCIENCE SYSTEMS AND APPLICATIONS, INC.	National Aeronautics and Space Administration	$493.81K	2015-06-10	2018-12-31	541712	IGF::OT::IGF NASA RESEARCH ANNOUCEMENT(NRA)IMPROVED COMPOSITE SOLAR SPECTRAL IRRADIANCE PRODUCT USING SBUV/2 AND OMI DATA. THE CONTRACTOR HAS PREVIOUSLY DEVELOPED A COMPOSITE SOLAR SPECTRAL IRRADIANCE DATA SET, USING MEASUREMENTS FROM 6 SEPARATE INSTRUMENTS. WAVELENGTH-DEPENDENT INTER-SATELLITE ABSOLUTE CALIBRATION ADJUSTMENTS WERE DEVELOPED BASED ON COMPARISONS TO A REFERENCE SOLAR SPECTRUM. NO REVISIONS WERE MADE TO THE TIME-DEPENDENT CALIBRATION ADJUSTMENTS APPLIED BY EACH INSTRUMENT TEAM. THIS DATA SET HAS BEEN EVALUATED IN PUBLICATIONS BY MULTIPLE INDEPENDENT GROUPS, AND SOME ARTIFACTS RELATED TO TRANSITIONS BETWEEN INSTRUMENTS AND UNCORRECTED DRIFTS IN SELECTED SPECTRAL AND TEMPORAL REGIONS HAVE BEEN IDENTIFIED. THE CONTRACTOR WILL UPDATE THIS DATA RECORD AND EXTEND IT TO THE PRESENT, USING MULTIPLE DATA SOURCES. WE WILL FIRST REVIEW OUR CURRENT COMPOSITE IRRADIANCE DATA SET TO IDENTIFY PLACES WHERE DATA GAPS CAN BE FILLED BY INTERPOLATION (USING TECHNIQUES SUCH AS SINGULAR VALUE DECOMPOSITION), AND REPLACING OUTLIER DATA POINTS, USING STATISTICAL APPROACHES SUCH AS AUTOREGRESSIVE ANALYSIS COMBINED WITH OUR UNDERSTANDING OF EACH INSTRUMENT S BEHAVIOR. IN ORDER TO EXTEND OUR COMPOSITE IRRADIANCE DATA SET BEYOND 2005, WE NOTE THAT DAILY SPECTRAL SOLAR IRRADIANCE MEASUREMENTS FROM THE NOAA-16 AND NOAA-17 SBUV/2 INSTRUMENTS BEGAN IN MARCH 2001 AND OCTOBER 2002 RESPECTIVELY. THESE MEASUREMENTS ARE CONSISTENT IN INSTRUMENT DESIGN AND DATA FORMAT WITH PREVIOUS MEASUREMENTS FROM THE NOAA-9 AND NOAA-11 SBUV/2 INSTRUMENTS, BUT DO NOT CURRENTLY INCLUDE A CORRECTION FOR LONG-TERM DEGRADATION. THE UARS SUSIM INSTRUMENT PERFORMED A VARIETY OF REFERENCE SOLAR MEASUREMENTS, WITH THE PRIMARY MISSION REFERENCE CHANNEL OBSERVATIONS OCCURRING APPROXIMATELY TWICE PER YEAR THROUGH THE END OF THE UARS MISSION IN AUGUST 2005. WE WILL USE THE SUSIM REFERENCE MEASUREMENTS TO CREATE TIME-DEPENDENT AND WAVELENGTH-DEPENDENT CALIBRATION CORRECTIONS FOR THESE SBUV/2 DATA SETS, FOLLOWING THE APPROACH PREVIOUSLY USED TO CREATE THE NOAA-9 AND NOAA-11 IRRADIANCE DATA SETS. BASED ON THAT EXPERIENCE, WE ANTICIPATE THAT THESE CORRECTIONS CAN BE EXTENDED THROUGH AT LEAST 2007 WITH REASONABLE ACCURACY. WE WILL THEN EXTEND THE NOAA-16 AND NOAA-17 DATA SETS THROUGH 2009 BY UTILIZING THE PROLONGED PERIOD OF SOLAR MINIMUM ACTIVITY BETWEEN CYCLE 23 AND 24 TO PROVIDE ADDITIONAL REFERENCE POINTS, FOLLOWING THE APPROACH USED TO ANALYZE AURA OMI IRRADIANCE DATA. FINALLY, CALIBRATED SOLAR SPECTRAL IRRADIANCE DATA FROM THE AURA OMI INSTRUMENT COVERING THE WAVELENGTH RANGE 270-500 NM ARE NOW AVAILABLE FROM 2007 TO THE PRESENT [MARCHENKO AND DELAND, 2014]. WE WILL COMPLEMENT AND SUBSTANTIALLY EXTEND, BOTH IN THE TIME AND WAVELENGTH DOMAINS, OUR REVISED COMPOSITE IRRADIANCE DATA SET WITH THESE HIGH-QUALITY MEASUREMENTS. AS WITH THE ORIGINAL COMPOSITE IRRADIANCE DATA SET, THERE ARE CERTAIN SPECTRAL REGIONS AND TIME PERIODS THAT ARE NOT FULLY REPRESENTED BY DIRECT MEASUREMENTS FOR THE CREATION OF THIS EXTENDED COMPOSITE PRODUCT (E.G. WAVELENGTHS LESS THAN 270 NM DURING THE OMI MISSION). WE WILL FILL THESE INTERVALS USING CALCULATED IRRADIANCE VARIATIONS BASED ON SCALED MG II INDEX MEASUREMENTS. THE SCALING FACTORS RELATING MG II INDEX VARIATIONS TO SPECTRAL IRRADIANCE CHANGES SHOW EXCELLENT CONSISTENCY BETWEEN SHORT-TERM AND LONG-TERM VARIATIONS, AND BETWEEN DIFFERENT SOLAR CYCLES. THIS GIVES US CONFIDENCE THAT WE CAN PROVIDE A HIGH QUALITY IRRADIANCE DATA SET WITH CONTINUOUS SPECTRAL AND TEMPORAL COVERAGE FOR USE IN ATMOSPHERIC MODELS. THE EXTENDED COMPOSITE SOLAR SPECTRAL IRRADIANCE DATA SET PRODUCED BY THIS PROPOSAL, USING NOAA-16 AND NOAA-17 SBUV/2 AND AURA OMI DATA, WILL PROVIDE A SELF-CONSISTENT REPRESENTATION OF SOLAR SPECTRAL VARIABILITY COVERING MORE THAN THREE SOLAR CYCLES, AND WILL ALSO BE INDEPENDENT OF ANY SORCE SOLSTICE AND SORCE SIM MEASUREMENTS DURING THE LIFETIME OF THE SORCE MISSION (2003-PRESENT).

National Aeronautics and Space Administration	$453.62K	2019-08-07	2023-02-06	541715	NASA'S OCEAN BIOLOGY AND BIOGEOCHEMISTRY PROGRAM FOCUSES ON DESCRIBING, UNDERSTANDING, AND PREDICTING THE BIOLOGICAL AND BIOGEOCHEMICAL REGIMES OF THE UPPER OCEAN, AS DETERMINED BY OBSERVATION OF AQUATIC OPTICAL PROPERTIES USING REMOTE SENSING DATA.
NNH12CD09C	SCIENCE SYSTEMS AND APPLICATIONS, INC.	National Aeronautics and Space Administration	$445.69K	2012-01-06	2016-07-05	541712	TREMENDOUS PROGRESS HAS BEEN MADE OVER THE LAST TWO DECADES IN QUANTIFYING THE GLOBAL DISTRIBUTION OF PRECIPITATION, PRINCIPALLY IN TROPICAL AND SUBTROPICAL LATITUDES. AT HIGH LATITUDES, VERY APPROXIMATE SATELLITE-BASED PRECIPITATION ESTIMATES ARE IN CURRENT USE, INCLUDING A CLOUD-VOLUME PROXY COMPUTATION WITH AIRS DATA THAT IS APPLIED IN THE GLOBAL PRECIPITATION CLIMATOLOGY PROJECT DATASETS BY THE INVESTIGATORS. AS A RESULT, CONSIDERABLE UNCERTAINTY REMAINS IN THE POLAR RESEARCH COMMUNITY AS TO THE UTILITY OF CURRENT PRECIPITATION ESTIMATES. THIS EFFORT IS TO ADVANCE THE STATE OF THE ART FOR ESTIMATING PRECIPITATION AT HIGH LATITUDES AND TO USE THESE IMPROVED ESTIMATES TO MAKE A NEW ASSESSMENT OF THE SEASONAL AND INTERANNUAL FLUCTUATIONS IN HIGH-LATITUDE PRECIPITATION. THE FIRST OBJECTIVE IN THE PROPOSED WORK IS TO AUGMENT THE EXISTING COMPLEMENT OF HIGH-LATITUDE PRECIPITATION ESTIMATES. THIS WILL BE DONE BOTH BY CONTINUING WORK CURRENTLY FUNDED THROUGH AQUA TO UPDATE THE CLOUD-VOLUME PROXY ALGORITHM CURRENTLY APPLIED TO AIRS DATA AND BY EXTENDING THE ALGORITHM TO WORK WITH SIMILAR PARAMETERS COMPUTED WITH MODIS DATA. THE SECOND OBJECTIVE IS TO ASSESS THE UTILITY OF THESE PROJECT-DEVELOPED DATASETS AS WELL AS EMERGING ALGORITHMS SUCH AS AMSU-BASED DATASETS AND SELECTED NUMERICAL MODEL DATASETS, LIKELY FROM GEOS5 OR MERRA. THE THIRD OBJECTIVE IS TO APPLY THE ASSESSMENT OF THE VARIOUS DATASETS TO CREATE BOTH OBSERVATION-ONLY AND JOINT OBSERVATION-MODEL DATASETS WITH NEARLY CONTINUOUS, UNIFORM, FINE-SCALE TIME AND SPACE COVERAGE AND A DATA RECORD SPANNING A DECADE OR LONGER. ACHIEVING THESE DATASETS WILL INCLUDE EXTENDING LAGRANGIAN TIME-INTERPOLATION METHODS TO HIGH LATITUDES, USING DISPLACEMENT FIELDS COMPUTED FROM THE PASSIVE MICROWAVE AND INFRARED OBSERVATIONS FROM TERRA, AQUA, AND OTHER LOW-EARTH-ORBIT SATELLITES. THE INVESTIGATORS ARE ALREADY COMPUTING MULTI-SATELLITE/ SENSOR PRECIPITATION DATASETS FOR LOW AND MIDDLE LATITUDES, SO THE GOAL WILL BE TO CREATE DATASETS THAT ARE GLOBALLY COMPLETE. THE FOURTH OBJECTIVE OF THIS PROJECT IS TO ANALYZE THESE GLOBAL MULTI-SATELLITE/SENSOR DATASETS TO PROVIDE A MORE ACCURATE DEFINITION OF THE TYPICAL SEASONAL CYCLE AT HIGH LATITUDES, TO EXPLORE THE INTERANNUAL FLUCTUATIONS AT HIGH LATITUDES, AND STUDY THE RESPONSE OF THE GLOBAL PRECIPITATION FIELDS TO THE MAJOR MODES OF LARGE-SCALE VARIABILITY. TAKING ADVANTAGE OF THE HIGH SPATIAL AND TEMPORAL RESOLUTION OF THE RESULTING DATA SETS, THE INVESTIGATORS WILL ALSO EXAMINE REGIONAL MANIFESTATIONS OF SIGNIFICANT WEATHER PHENOMENA IN ASSOCIATION WITH LARGE-SCALE CLIMATE VARIABILITY (INCLUDING ENSO, NAO, AND MJO) AND HOW THEY ARE REPRODUCED BY MODERN-ERA NUMERICAL MODELS. THIS INVESTIGATION ADDRESSES HIGH-PRIORITY EARTH SCIENCE QUESTIONS RELATED TO QUANTIFYING REGIONAL AND GLOBAL WEATHER AND CLIMATE PATTERNS, AS WELL AS OUR ABILITY TO MODEL THEM.
NNH12CF94C	SCIENCE SYSTEMS AND APPLICATIONS, INC.	National Aeronautics and Space Administration	$441.59K	2012-10-01	2017-09-30	541712	IGF::OT::IGF OTHER FUNCTIONS PROPOSAL TITLE: AN EMPIRICAL APPROACH TO ATTRIBUTION OF LONG-TERM CHANGES IN PMC. POLAR MESOSPHERIC CLOUD (PMC) DATA FROM SOLAR BACKSCATTERED ULTRAVIOLET (SBUV) INSTRUMENTS SHOW LONG-TERM INCREASES IN PMC OCCURRENCE FREQUENCY AND BRIGHTNESS SINCE 1978, AS WELL AS AN ANTI-CORRELATION WITH SOLAR ACTIVITY. THE SBUV PMC ALGORITHM ONLY DETECTS THE BRIGHTEST FRACTION OF THE PMC POPULATION. 3-D ATMOSPHERIC MODEL SIMULATIONS ALSO PRODUCE LONG-TERM PMC TRENDS, BUT THE MAGNITUDE OF THESE TRENDS DEPENDS ON THE PMC BRIGHTNESS THRESHOLD USED IN THE ANALYSIS. THESE SIMULATIONS HAVE NOT CLEARLY IDENTIFIED THE FORCING MECHANISM RESPONSIBLE FOR THE LONG-TERM PMC CHANGES. WE PROPOSE TO USE DATA FROM THE CLOUD IMAGING AND PARTICLE SIZE (CIPS) AND SOLAR OCCULTATION FOR ICE EXPERIMENT (SOFIE) INSTRUMENTS ON THE AERONOMY OF ICE IN THE MESOSPHERE (AIM) SPACECRAFT TO CLARIFY THE ROLES OF TEMPERATURE AND WATER VAPOR AS DRIVERS FOR LONG-TERM PMC CHANGES. SOFIE SIMULTANEOUSLY PROVIDES VERTICAL PROFILES OF PMC EXTINCTION WITH HIGH SENSITIVITY AND HIGHLY ACCURATE MEASUREMENTS OF TEMPERATURE AND WATER VAPOR CONDITIONS IN THE ATMOSPHERIC REGION WHERE PMCS FORM AND EVOLVE. CIPS PROVIDES HIGH SPATIAL RESOLUTION OBSERVATIONS OF PMCS WITH COMPLETE HEMISPHERIC COVERAGE. THE 4 YEARS OF AIM DATA CURRENTLY AVAILABLE WILL BE ANALYZED TO EVALUATE CORRELATIONS BETWEEN PMC BEHAVIOR OBSERVED BY BOTH CIPS AND SOFIE WITH ATMOSPHERIC BEHAVIOR OBSERVED BY SOFIE. WE WILL USE ICE WATER CONTENT (IWC) AS A COMMON PARAMETER TO RELATE THE DISPARATE PMC MEASUREMENT TECHNIQUES OF CIPS AND SOFIE. THIS ANALYSIS WILL BENEFIT FROM THE LOW LEVEL OF SOLAR ACTIVITY DURING THE AIM MISSION. ADDITIONAL MESOSPHERIC TEMPERATURE AND WATER VAPOR DATA EXTENDING BACK TO 2002 ARE ALSO AVAILABLE FROM THE SOUNDING OF THE ATMOSPHERE USING BROADBAND EMISSION RADIOMETRY (SABER) INSTRUMENT ON THE THERMOSPHERE-IONOSPHERE-MESOSPHERE ENERGETICS AND DYNAMICS (TIMED) SPACECRAFT, AND THE MICROWAVE LIMB SOUNDER (MLS) INSTRUMENT ON THE AURA SPACECRAFT. WE WILL ANALYZE THESE DATA IN COMBINATION WITH STUDENT NITRIC OXIDE EXPLORER (SNOE) PMC DATA TO UNDERSTAND HOW THE PMC RESPONSE TO TEMPERATURE AND WATER VAPOR CHANGES WHEN SOLAR ACTIVITY IS SIGNIFICANTLY HIGHER. SINCE SBUV PMC DATA ARE AVAILABLE DURING THIS ENTIRE PERIOD, WE CAN THEN DETERMINE APPROPRIATE THRESHOLD VALUES TO ENSURE THAT THESE RESULTS ARE APPROPRIATE FOR THE LOWER SENSITIVITY SBUV MEASUREMENTS. OUR RESULTS WILL GIVE MORE INSIGHT INTO HOW ACCURATELY THE TRENDS DERIVED FROM THE SBUV PMC DATA REFLECT BOTH THE ENTIRE PMC POPULATION AND BACKGROUND ATMOSPHERE CHANGES.

National Aeronautics and Space Administration	$365.14K	2016-10-01	2019-09-30	541712	IGF::OT::IGF NASA RESEARCH ANNOUNCEMENT AWARD THIS CONTRACT IS FOR THE INVESTIGATION OF AEROSOL-CLOUD INTERACTIONS AND THE AEROSOL INDIRECT EFFECT IN MARINE LOW CLOUDS BY COMBINING AEROSOL EXTINCTION DERIVED FROM CALIOP WITH COLLOCATED CLOUD PROPERTIES DERIVED FROM THE MODERATE RESOLUTION IMAGING SPECTRORADIOMETER (MODIS). THE SPECIFIC FOCUS WILL BE ON THE AEROSOL VERTICAL STRUCTURE AND THE ATMOSPHERIC FACTORS THAT MODIFY THE CLOUD-AEROSOL RELATIONSHIP IN DIFFERENT REGIONS. THE PROJECT WILL ALSO EVALUATE NEW METHODS TO COMBINE CALIOP AEROSOL PRODUCTS WITH OTHER A-TRAIN DATASETS. THE OBSERVATIONAL RELATIONSHIPS WILL BE FURTHER UTILIZED TO CALCULATE THE CLOUD ALBEDO SUSCEPTIBILITY TO CHANGES IN THE AEROSOL EXTINCTION COEFFICIENT BY MEANS OF RADIATIVE OBSERVATIONS FROM THE CLOUDSAT AND EARTH RADIANT ENERGY SYSTEM (CERES) AND RADIATIVE TRANSFER SIMULATIONS. NUMERICAL EXPERIMENTS WITH THE HIGH-RESOLUTION WEATHER RESEARCH AND FORECASTING MODEL COUPLED WITH CHEMISTRY MODULE (WRF-CHEM) WILL BE CONDUCTED TO PROVIDE THE PHYSICAL INTERPRETATION OF THE OBSERVED CORRELATIONS AND EVALUATE THE RELATIVE IMPORTANCE OF FREE TROPOSPHERIC AND BOUNDARY LAYER AEROSOLS. PARTICULAR EMPHASIS WILL BE GIVEN TO THE AEROSOL VERTICAL VARIABILITY, AEROSOL HUMIDIFICATION AND ENTRAINMENT RATE. OVERALL, THIS ANALYSIS WILL LEAD TO A MORE ACCURATE QUANTIFICATION OF THE AEROSOL INDIRECT EFFECTS AS WELL AS A BETTER UNDERSTANDING OF THE BIASES ASSOCIATED WITH ACI ESTIMATES BASED ONLY ON PASSIVE SATELLITE SENSORS.

NNH14CK39C	SCIENCE SYSTEMS AND APPLICATIONS, INC.	National Aeronautics and Space Administration	$305.15K	2014-03-11	2018-03-31	541712	IGF::OT::IGF OTHER FUNCTION THIS EFFORT IS TO UTILIZE CALLOP AND MODIS DATA TO CREATE A CLIMATOLOGY OF BLOWING SNOW OCCURRENCE TO STUDY ITS EFFECT ON THE MASS BALANCE OF THE ANTARTIC AND GREENLAND ICE SHEETS AND ITS POSSIBLE RELATIONSHIP WITH THE CLIMATE CHANGE. THE WORLD'S GREAT ICE SHEETS COVERING GREENLAND AND ANTARCTICA ARE HIGHLY DYNAMIC SYSTEMS INTERACTING WITH ATMOSPHERIC AND OCEANIC PROCESSES THAT ULTIMATELY CONTROL THEIR FATE. GROWTH OR SHRINKAGE OF THESE ICE SHEETS DEPENDS ON THE INTERPLAY OF MANY COMPLICATED AND INTERACTING PROCESSES. SURFACE MASS BALANCE (SMB) DISTRIBUTION AND ITS TEMPORAL AND SPATIAL VARIABILITY IS AN ESSENTIAL INPUT PARAMETER IN MASS BALANCE STUDIES. PRECIPITATION AND WIND DRIVEN TRANSPORT AND SUBLIMATION OF SNOW ARE THE IMPORTANT COMPONENTS OF SMB OVER MOST OF ANTARCTICA. NEAR THE COASTS AND OVER PARTS OF THE ANTARCTIC PENINSULA, MELTING MAY ALSO BE A SIGNIFICANT TERM, BUT OVER MOST OF THE ANTARCTIC INTERIOR, PRECIPITATION AND WIND-DRIVEN SNOW PROCESSES DOMINATE. WE PROPOSE TO UTILIZE CALIOP AND MODIS DATA TO CREATE A CLIMATOLOGY OF BLOWING SNOW OCCURRENCE TO STUDY ITS EFFECT ON THE MASS BALANCE OF THE ANTARCTIC AND GREENLAND ICE SHEETS AND ITS POSSIBLE RELATIONSHIP WITH CLIMATE CHANGE. AS CLIMATE AND OCEAN TEMPERATURE WARMS, IT IS EXPECTED THAT ICE WILL MELT NEAR THE COASTS ACCELERATING GLACIER ADVANCE AND FURTHER MELTING. HOWEVER, A WARMER ATMOSPHERE CAN HOLD MORE MOISTURE LEADING TO INCREASED PRECIPITATION THEREBY ADDING MASS TO THE ICE SHEETS. IT IS NOT CLEAR WHAT EFFECT WILL DOMINATE IN A CHANGING CLIMATE. DUE TO THE SCARCITY OF OBSERVATIONS, PRECIPITATION OVER ANTARCTICA CAN ONLY BE ESTIMATED FROM MODELS AND IS KNOWN TO LACK ACCURACY. BLOWING SNOW DEPENDS ON TWO FACTORS: WIND SPEED AND THE AVAILABILITY OF SNOW. THE LATTER IS OBVIOUSLY RELATED TO PRECIPITATION. THE SOUTHERN ANNULAR MODE (SAM) INDEX IS KNOWN TO BE RELATED TO PRECIPITATION OVER ANTARCTICA. UTILIZING THE 6 TO 9 YEAR RECORD OF BLOWING SNOW FREQUENCY THAT THIS WORK WILL CREATE, WE INTEND TO LOOK FOR CONNECTIONS BETWEEN BLOWING SNOW FREQUENCY AND THE SAM INDEX AND ALSO ENSO. DETERMINING THE TREND OF BLOWING SNOW FREQUENCY MAY GIVE US INSIGHT INTO CHANGES IN PRECIPITATION AND WIND SPEED, BOTH OF WHICH MAY BE AFFECTED BY A WARMING CLIMATE. WE WILL ALSO LOOK AT THE EFFECTS OF BLOWING SNOW ON RADIATIVE BALANCE AND ATMOSPHERIC MOISTURE.
NNH12CF57C	SCIENCE SYSTEMS AND APPLICATIONS, INC.	National Aeronautics and Space Administration	$290.25K	2012-09-28	2016-09-27	541712	IGF::OT::IGF OTHER FUNCTIONS - NRA AWARD ENTITLED: THE STUDY OF CLOUDS, BLOWING SNOW AND SNOW-ICE PENETRATION IN SUPPORT OF THE ICESAT-II MISSION. THE ATMOSPHERE, AND MORE SIGNIFICANTLY, CLOUDS AND BLOWING SNOW PRESENT FORMIDABLE CHALLENGES TO HIGH PRECISION ALTIMETRY OF ICE SHEETS AND SEA ICE FROM SPACE. A COMPLETE UNDERSTANDING OF THE LASER PULSE INTERACTION WITH THE SURFACE IS ESSENTIAL. OUR TEAM HAS EXPERIENCE IN ATMOSPHERIC SCIENCE, SATELLITE REMOTE SENSING, AND RADIATIVE TRANSFER AND ALSO HAS A SOLID UNDERSTANDING OF THE OBJECTIVES, REQUIREMENTS AND CHALLENGES OF SPACE-BASED LASER ALTIMETRY. THIS EFFORT SEEKS TO CONTINUE RESEARCH ON POLAR CLOUD AND BLOWING SNOW DISTRIBUTIONS AND VARIABILITY AND LASER PULSE-SURFACE INTERACTIONS IN AN EFFORT TO ULTIMATELY AID THE INTERPRETATION AND ACCURACY OF ICESAT-II MEASUREMENTS. EFFORTS WILL BE ORGANIZED INTO THREE MAIN TASKS: 1. FOR CLIMATE RESEARCH AND TO PROVIDE CLIMATOLOGY FOR ICESAT-II, TO STUDY THE DISTRIBUTION, TRENDS, AND VARIABILITY OF POLAR CLOUD AND BLOWING SNOW PROPERTIES. 2. IN SUPPORT OF THE ICESAT-II ALTIMETRY MEASUREMENTS, TO STUDY THE EFFECTS OF SNOW AND ICE PENETRATION OF LASER PULSE AND APPROACHES TO MITIGATE THIS EFFECT. 3. WITH RESULTS FROM ABOVE TASKS AND THE USE OF SIMULATED ICESAT-II DATA AND MABEL DATA, DEVELOP ALGORITHMS TO MAXIMIZE INFORMATION EXTRACTION AND MINIMIZE ERROR FROM FORWARD SCATTERING AND SURFACE PENETRATION. IN ADDITION TO ITS OWN SCIENTIFIC MERIT, TASK 1 IS IMPORTANT FOR UNDERSTANDING THE AREAS AND SEASONS WHEN CLOUDS AND BLOWING SNOW WILL HAVE THE LARGEST EFFECT ON ICESAT-II MEASUREMENTS IN TERMS OF DATA LOSS AND RANGE DELAY. TASK 2 IS IMPORTANT FOR RANGING ACCURACY OVER SNOW AND ICE SURFACES WITH SPECIAL RELEVANCE TO SEA ICE THICKNESS DETERMINATION. TASK 3 IS ESSENTIAL FOR DEVELOPMENT OF ROBUST AND ACCURATE ICESAT-II ALGORITHMS AND ULTIMATELY ICESAT-II DATA PRODUCTS. THIS EFFORT IS RELEVANT TO NASA S STRATEGIC GOAL 3A, TO STUDY EARTH FROM SPACE TO ADVANCE SCIENTIFIC UNDERSTANDING AND MEET SOCIETAL NEEDS. ICESAT-II WILL PROVIDE VALUABLE DATA ON THE RAPID CHANGES OCCURRING IN THE CRYOSPHERE AS WELL AS PROVIDE IMPORTANT DATA ON THE EARTH S BIOMASS AND CLOUDS. THE INTENT OF THIS RESEARCH IS TO HELP IN DEFINING THE SPECIFICATIONS OF THE ICESAT-II MISSION THROUGH A THOROUGH CHARACTERIZATION OF THE ATMOSPHERIC AND LASER-SURFACE INTERACTION EFFECTS THAT WILL GREATLY IMPACT THE ALTIMETRY MEASUREMENTS. THE OVERALL GOAL IS TO HELP IN DEFINING THE BEST POSSIBLE ICESAT-II INSTRUMENT AND MISSION.
