RECEPTIVITY AND TRANSITION OVER BLUNT CONFIGURATIONS UNDER NOISY AND QUIET HYPERSONIC CONDITIONS

WE PROPOSE A SERIES OF BALLOON CAMPAIGNS WHICH WILL TAKE PLACE EVERY SUMMER IN 2021 2022 AND 2023 IN INDIA AND SAUDI ARABIA TO STUDY THE NATURE ORIGIN AND FORMATION OF THE ATAL.

MISSION OVERVIEW AND PLATFORMS: ACTIVATE WILL DEPLOY TWO COMPLEMENTARY AIRCRAFT OVER THE WESTERN NORTH ATLANTIC OCEAN - THE NASA LARC HU-25 FALCON AND B-200 KING AIR. THE HU-25 ACQUIRES IN SITU MEASUREMENTS BELOW IN AND ABOVE CLOUDS. THE B-200 FLIES ABOVE CLOUDS TO REMOTELY MEASURE AEROSOLS AND CLOUDS USING THE HIGH SPECTRAL RESOLUTION LIDAR-2 (HSRL-2) THE RESEARCH SCANNING POLARIMETER (RSP) AND DEPLOYS DROPSONDES TO MEASURE THE ATMOSPHERIC STATE. SINCE BOTH AIRCRAFT AND THE MAJORITY OF IN SITU AND REMOTE SENSING INSTRUMENTS ARE BASED AT LARC ADJACENT TO THE WESTERN ATLANTIC STUDY REGION ACTIVATE WILL ACQUIRE A STATISTICALLY ROBUST DATASET THROUGH AN EXTENSIVE SERIES OF FLIGHTS (~50 JOINT AIRPLANE MISSIONS PER YEAR) IN EACH OF THREE YEARS (~600 HOURS AND ~150 FLIGHTS OVER THREE YEARS FOR EACH AIRPLANE). WE WILL SAMPLE A WIDE RANGE OF AEROSOL AND CLOUD CONDITIONS BY PLANNING FEBRUARY JUNE FLIGHTS. INSTRUMENTS AND MODELS: ALL INSTRUMENTS REQUIRED FOR ACTIVATE SCIENCE OBJECTIVES ARE MATURE (TRL 9); THESE ADVANCED ACTIVE AND PASSIVE REMOTE SENSING AND IN SITU INSTRUMENTS PROVIDE A LOW-RISK HIGH-IMPACT APPROACH FOR BOTH OBTAINING CRITICAL ATMOSPHERIC MEASUREMENTS TO RELATE AEROSOLS CLOUDS AND METEOROLOGY AND IMPROVING MODELS. ACTIVATE ALSO PROVIDES A UNIQUE OPPORTUNITY TO EVALUATE THE ABILITY OF A NEW COMPACT AIRBORNE RADIOMETER TO PROVIDE AN ADDITIONAL CLOUD LIQUID WATER PATH MEASUREMENT. ACTIVATE INCLUDES A SUITE OF MULTI-SCALE MODELS AND A DIVERSE SCIENCE ANALYSIS AND MODELING TEAM WITH BROAD EXPERTISE IN INTEGRATING AIRBORNE AND SATELLITE DATA TO ADVANCE OUR KNOWLEDGE OF AEROSOLCLOUD- METEOROLOGY INTERACTIONS. THE ACTIVATE TEAM BRINGS TOGETHER EXPERTS IN AIRBORNE IN SITU AND REMOTE SENSING MEASUREMENTS AND ANALYSES MODEL DEVELOPMENT SATELLITE RETRIEVALS AND FIELD CAMPAIGN LEADERSHIP.

TAS::57 3600::TAS "ELECTROACTIVE RADIATION-SHIELDING BORON NITRIDE POLYMER COMPOSITES"

CLOUD SCAVENGING IS THE DOMINANT REMOVAL PROCESS FOR A WHOLE SUITE OF AEROSOLS BUT MODEL PARAMETERIZATIONS OF THIS PROCESS ARE HIGHLY UNCERTAIN SUBSTANTIALLY CONTRIBUTING TO LARGE UNCERTAINTIES IN THE SIMULATED LOADINGS AND RADIATIVE FORCING OF AEROSOLS. IPCC AR5 HAS IDENTIFIED THE IMPROVEMENT OF WET DEPOSITION AND SCAVENGING PARAMETERIZATIONS IN LARGE-SCALE MODELS AS A PRIORITY. THE CURRENT WET SCAVENGING PARAMETERIZATION IN THE NASA GEOS-5 MODEL IS NOT EXPLICITLY LINKED TO CLOUD DROPLET AND ICE CRYSTAL NUCLEATION. RECENT DEVELOPMENT OF TWO-MOMENT CLOUD MICROPHYSICS IN GEOS-5 ALLOWS TREATING CLOUD SCAVENGING OF AEROSOLS MORE PHYSICALLY WITH SELF- CONSISTENCY. WE PROPOSE A 4-YEAR PROJECT TO DEVELOP MORE PHYSICALLY-BASED PARAMETERIZATIONS OF WET SCAVENGING AND STUDY THE IMPACT OF THEIR UNCERTAINTIES ON AEROSOL DIRECT AND INDIRECT EFFECTS IN GEOS-5. OUR RESEARCH OBJECTIVES ARE: (1). DEVELOP A MORE PHYSICALLY DETAILED SIZE-DEPENDENT BELOW-CLOUD SCAVENGING PARAMETERIZATION BY RAIN AND SNOW IN THE GEOS-5 MODEL (2). DEVELOP MORE PHYSICALLY BASED SIZE-DEPENDENT PARAMETERIZATIONS OF IN-CLOUD (NUCLEATION AND IMPACTION) SCAVENGING OF AEROSOLS IN THE FRAMEWORK OF AEROSOL-CLOUD INTERACTIONS (GOCART BULK AEROSOL OR MODAL AEROSOL MODULE AEROSOL MICROPHYSICS COUPLED WITH TWO-MOMENT CLOUD MICROPHYSICS) IN GEOS-5. (3). ASSESS THE IMPACTS OF THE NEW AEROSOL SCAVENGING PARAMETERIZATIONS ON THE GEOS-5 SIMULATED AEROSOL MASS AND NUMBER CONCENTRATIONS SIZE DISTRIBUTION DEPOSITION FLUXES AND AEROSOL OPTICAL DEPTHS AND EVALUATE WITH SURFACE IN SITU AND SATELLITE OBSERVATIONS. QUANTIFY THE UNCERTAINTIES IN THOSE PARAMETERIZATIONS AND THEIR IMPACTS ON GEOS-5 AEROSOL SIMULATIONS. (4). ASSESS THE IMPACTS OF THE NEW AEROSOL SCAVENGING PARAMETERIZATIONS ON CLOUD PROPERTIES AND PRECIPITATION AND EVALUATE WITH SATELLITE AND SURFACE OBSERVATIONS. EXAMINE THE INFLUENCE OF UNCERTAINTIES IN THOSE PARAMETERIZATIONS ON AEROSOL DIRECT AND INDIRECT EFFECTS UPON THE CLIMATE SYSTEM (CLOUD AND PRECIPITATION). THIS PROJECT WILL RESULT IN MORE PHYSICALLY-BASED PARAMETERIZATIONS OF AEROSOL SCAVENGING BY RAIN AND SNOW IN GEOS-5 AND WILL IMPROVE CONFIDENCE IN OUR ESTIMATES OF AEROSOL BURDEN LIFETIME AND DIRECT AND INDIRECT EFFECTS. THIS PROPOSAL DIRECTLY RESPONDS TO THE RESEARCH THEME "CONSTITUENTS IN THE CLIMATE SYSTEM" IN THE SOLICITATION BY IMPROVING OUR UNDERSTANDING OF THE PROCESS OF CLOUD SCAVENGING OF AEROSOLS AND ITS REPRESENTATION IN THE NASA GEOS-5 MODEL. THIS RESEARCH ADDRESSES NASA'S STRATEGIC GOAL 3A1 TO "UNDERSTAND AND IMPROVE PREDICTIVE CAPABILITY FOR CHANGES IN THE OZONE LAYER CLIMATE FORCING AND AIR QUALITY ASSOCIATED WITH CHANGES IN ATMOSPHERIC COMPOSITION."

THIRD-ORDER HYPERBOLIC NAVIER-STOKES SOLVER FOR UNSTEADY SIMULATIONS WITH ADAPTIVE SPACE-TIME UNSTRUCTURED GRIDS

WILDLAND FIRE IS LARGELY UNDER THE CONTROL OF WEATHER AND CLIMATE AND EXTREME FIRES ARE INCREASING COMPELLING US TO IMPROVE UNDERSTANDING OF THE CONNECTIONS BETWEEN FUELS FIRE WEATHER ATMOSPHERIC CHEMISTRY AND SMOKE TRANSPORT WHICH ARE CRITICAL TO UNDERSTANDING IMPACTS ON AIR QUALITY ATMOSPHERIC CHEMISTRY AND CLIMATE. IN A DIRECT RESPONSE TO THE FIRECHEM CALL WE PROPOSE TO PROVIDE SUPPORT TO GUIDE FLIGHT PLANNING THAT INCLUDES: (1) PREPARE PRECAMPAIGN INTELLIGENCE ON LOCATIONS WHERE CROPLAND PRESCRIBED AND WILDLAND FIRES ARE EXPECTED; (2) PROVIDE SATELLITE AND GROUND-BASED NEAR-REAL-TIME OBSERVATIONS AND INTERPRETATION OF FIRE ACTIVITY AND SMOKE EXTENT; (3) PROVIDE FIRE WEATHER AS AN INDICATOR OF ACTIVE FIRE CONTINUANCE; (4) PROVIDE THE LOCATION OF AREAS WITH THE BEST CHARACTERIZED FUELS; (5) PROVIDE INTELLIGENCE ON ACTIONED AND EXPERIMENTAL FIRES; (6) PROVIDE THE LOCATIONS AND TIMING OF PLANNED PRESCRIPTION AND/OR CROPLAND FIRES; AND (7) PREPARE DAILY REPORTS FOR FLIGHT PLANNING AND SUMMARY SYNOPSIS REPORTS OF THE FIRES SAMPLED DURING THE CAMPAIGN. ALSO WE PROPOSE TO USE THE DATA AND INFORMATION COLLECTED PARTICULARLY ON SMALL CROPLAND AND PRESCRIBED BURNS TO ANALYZE THE CAPABILITY OF SATELLITES TO CHARACTERIZE THESE FIRES. TOGETHER OUR PROPOSED WORK ADDRESSES 3 OF THE 4 FIRECHEM NEEDS STATED IN THE WHITE PAPER: (2) PREDICTION OF SMALL FIRE ACTIVITY. ARE THERE ORGANIZED PLANS FOR BURNING? WHEN ARE FIRES EXPECTED TO START? WHERE ARE CONDITIONS CONDUCIVE TO BURNING? CAN GOES PROVIDE GUIDANCE OR UPDATES ON BURNING PROGRESS?; (3) CONNECTION TO GROUND CONDITIONS. GATHERING INFORMATION ON FUEL CONDITIONS FIRE BEHAVIOR DURATION FRACTION OF FUEL BURNED ETC.; AND (4) ADVICE ON SELECTION OF FIRES TO TARGET. WHICH FIRE IS LIKELY TO YIELD MORE INFORMATION? WE BELIEVE THE BASE INFORMATION THAT WILL BE PROVIDED BY THIS PROJECT IS NECESSARY TO EXPLORE AND DEFINE THE VARIABILITY IN EMISSIONS OF GASES AEROSOLS AND AEROSOL PRECURSORS AS THEY RELATE TO SPECIFIC FIRES (SIZE CLASS SURFACE INTERMITTENT CROWN) IN UNIQUE ECOSYSTEMS AND FUEL TYPES UNDER A VARIETY OF FIRE-WEATHER CONDITIONS. THE FIRE RELEVANT DATA PRODUCED BY OUR TEAM IS EXPECTED TO BE RELEVANT TO THE COMPOSITION AND INJECTION HEIGHT OF PLUMES AIR QUALITY AND CHEMISTRY AND THE IMPACT OF BIOMASS BURNING ON CLIMATE-RELEVANT PROPERTIES. WE ANTICIPATE SMOKE COMPOSITION WILL BE VARIABLE DEPENDENT ON FUEL TYPE AMOUNT STRUCTURE COMBUSTION ENVIRONMENT (SPECIFICALLY THOSE RELATED TO FLAMING VS SMOLDERING COMBUSTION) AND ANTECEDENT WEATHER FACTORS. THESE BASE DATA ARE CRITICAL TO ADDRESSING RESEARCH QUESTIONS RELATED TO TROPOSPHERIC SAMPLING TO DISTINGUISH DIFFERENCES FROM AIRCRAFT AND SPACE-BASED OBSERVATIONS AND INTERPRETING THE DEGREE TO WHICH THESE DIFFERENCES IMPACT REGIONAL AND GLOBAL AIR QUALITY AND CLIMATE. OUR TEAM IS WELL POSITION TO ACCOMPLISH THIS WORK WITH EXPERTISE IN WORKING WITH: FIRES (ENTIRE TEAM) SATELLITE DATA (SOJA MCCARTY HUDAK) FUELS (ENTIRE TEAM) FIRE WEATHER (SOJA HUDAK) CROPLANDS (MCCARTY) PRESCRIBED BURNING (HIERS) AND WESTERN FIRES (HUDAK). OUR TEAM IS ALREADY INTERACTIVE WITH THE COMBINED INTERAGENCY CAMPAIGNS AND OUR COLLABORATORS ARE ACTIVELY ENGAGED.
