  THE DIGITAL ARRAY GAS RADIOMETER (DAGR) IS A NEW SENSOR DESIGN FOR ACCURATE MEASUREMENT AND MONITORING OF TRACE GASES IN THE BOUNDARY LAYER FROM SPACE, AIRCRAFT, OR GROUND-BASED PLATFORMS USING SCATTERED SUNLIGHT. TARGET GASES INCLUDE CH4, CO, CO2, N 2O AND OTHER SPECIES CRITICAL TO CLIMATE SCIENCE, ENVIRONMENTAL MONITORING AND COMMERCIAL POLLUTION COMPLIANCE EFFORTS. THE DAGR APPROACH BUILDS ON TRADITIONAL GAS-FILTER CORRELATION RADIOMETRY (GFCR), A WELL-KNOWN AND PROVEN TECHNOLOGY FOR TRACE GAS SENSING. THE EFFECTIVENESS OF GFCR, HOWEVER, HAS HISTORICALLY BEEN LIMITED IN DOWNLOOKING APPLICATIONS PRIMARILY BECAUSE VARIATIONS IN SURFACE ALBEDO DEGRADE ITS PERFORMANCE. IN OUR PHASE I EFFORT, WE INVESTIGATED AND DEMONSTRATED THE ABILITY OF THE DAGR DESIGN TO OVERCOME THESE LIMITATIONS. WITH THE SUCCESSFUL COMPLETION OF THESE FEASIBILITY STUDIES, THE TECHNOLOGY HAS BEEN INCREASED TO TRL-3. IN THE PHASE II EFFORT, WE WILL CONSTRUCT AND TEST A PROTOTYPE DAGR SENSOR FOR CH4 DETECTION AND MONITORING, ADVANCING THE TECHNOLOGY TO TRL-5. CH4 WAS CHOSEN AS OUR TARGET GAS TO MEET THE PRESSING COMMERCIAL NEED FOR AN IMPROVED NATURAL GAS LEAK DETECTION SYSTEM. FOR NASA, THE DAGR PROTOTYPE WILL SIGNIFICANTLY ADVANCE THE TECHNOLOGY NEEDED FOR FUTURE MISSIONS SUCH AS ASCENDS, GEOCAPE, AND GACM. DAGR REPRESENTS A MAJOR ADVANCE IN USING BACKSCATTERED LIGHT FOR DETECTING CONCENTRATIONS OF KEY MOLECULAR SPECIES.

  IGF::OT::IGF OTHER FUNCTIONS- OBSERVATIONAL AND NUMERICAL STUDIES OF PLANETARY WAVE-TIDE INTERACTION IN THE LOWER THERMOSPHERE. ADVECTIVE PROCESSES THAT COUPLE PLANETARY WAVES (PWS) WITH TIDES HAVE BEEN PROPOSED AS IMPORTANT SOURCES OF NONMIGRATING TIDES. BECAUSE TIDES ARE GLOBAL-SCALE PHENOMENA WITH DEEP VERTICAL WAVELENGTHS, AN IMPORTANT CONSEQUENCE OF THEIR INTERACTION WITH PWS IS THAT THE WINTER STRATOSPHERE CAN BE DIRECTLY COUPLED TO THE SUMMER HEMISPHERE. THIS MECHANISM HAS ALSO BEEN SHOWN TO LINK PW-INDUCED SUDDEN STRATOSPHERIC WARMING EVENTS TO IONOSPHERIC VARIABILITY. HOWEVER, WHILE MANY STUDIES HAVE REPORTED VARIOUS CONNECTIONS BETWEEN TIDES AND PWS, OBSERVATIONAL EVIDENCE FOR THE ACTUAL TIDE-PW INTERACTION MECHANISM IS VERY SPARSE. SEVERAL STUDIES HAVE UTILIZED SATELLITE DATASETS TO DETECT THE WAVENUMBER TRIAD ASSOCIATED WITH TIDE-PW INTERACTION. HOWEVER, THE AVAILABLE DATA WERE TOO LIMITED IN DURATION AND VERTICAL EXTENT TO CONFIRM THE MECHANISM, AND ITS IMPLICATIONS FOR CROSS-HEMISPHERE AND IONOSPHERIC COUPLING. THE OBJECTIVES OF THIS RESEARCH ARE TO DELINEATE VARIABILITY IN THE MLT AND IN THE THERMOSPHERE DUE TO TIDE-PW INTERACTION. SPECTRAL TECHNIQUES THAT HAVE BEEN APPLIED TO UARS AND TIMED DATA FOR TIDAL ANALYSIS ARE INSUFFICIENT FOR STUDYING TIDE-PW INTERACTIONS. THE REASON IS THAT THESE PROCESSES OCCUR ON TIME SCALES THAT ARE SHORTER THAN THE SLOW PRECESSION RATES REQUIRED TO OBTAIN THE TEMPORAL COVERAGE NECESSARY FOR TIDAL ANALYSIS. THE PROPOSED RESEARCH WILL OVERCOME THIS SHORTCOMING BY USING AN APPROACH THAT ALLOWS FOR TIDAL ANALYSIS ON TIME SCALES OF UNDER ONE WEEK. WE WILL SYNERGISTICALLY EMPLOY DATA FROM THE TIMED AND EOS SATELLITES TO DIAGNOSE PWS AND DIURNAL TIDES, USING A DECONVOLUTION METHOD SUCCESSFULLY APPLIED TO OTHER DATASETS. WE WILL APPLY DIAGNOSTIC METHODS BASED ON HOUGH MODE EXTENSIONS TO OBTAIN AND VALIDATE GLOBAL TIDAL WINDS. WE WILL USE A NUMERICAL MODEL TO DIAGNOSE THE MECHANISMS AND ORIGINS OF TIDE-PW INTERACTIONS.

  IGF::OT::IGF OTHER FUNCTIONS TITLE: COUPLING WITHIN THE NEUTRAL ATMOSPHERE -IONOSPHERE SYSTEM FROM 80 TO 800 KM BY TIDES, PLANETARY WAVES, AND GRAVITY WAVES LARGE- AND SMALL-SCALE WAVES IN THE NEUTRAL ATMOSPHERE ARE NOW KNOWN TO PENETRATE TO HIGH ALTITUDES IN THE THERMOSPHERE AND TO HAVE SIGNIFICANT SIGNATURES IN PLASMA QUANTITIES. MEAN RESPONSES OF THE NEUTRAL ATMOSPHERE TO THESE MOTIONS, E.G. SUDDEN STRATOSPHERIC WARMINGS (SSWS), ALSO APPEAR TO INDUCE CLEAR RESPONSES IN THE IONOSPHERE. YET THE MECHANISMS ACCOUNTING FOR NEUTRAL MOTIONS AT HIGHER ALTITUDES, AND FOR THEIR SIGNATURES IN THE IONOSPHERE, ARE LARGELY UNKNOWN AT THIS TIME. IONOSPHERIC RESPONSES TO THESE NEUTRAL MOTIONS ARE NEVERTHELESS IMPORTANT BECAUSE OF THE INFLUENCES SUCH MOTION! APPEAR TO HAVE ON IONOSPHERIC STRUCTURE AND VARIABILITY, THE IONOSPHERIC DYNAMOS, COMMUNICATION AND NAVIGATION SYSTEMS, AND SPACE WEATHER FORECASTING. IN PARTICULAR, BOTH TIDES AND GRAVITY WAVES (GWS) APPEAR TO HAVE SIGNIFICANT INFLUENCES ON THE SEEDING CONDITIONS AND OCCURRENCE STATISTICS OF EQUATORIAL PLASMA HUBBIES THAT MAY PENETRATE TO VERY HIGH ALTITUDES, WHILE PLANETARY WAVES (PWS) AND SSWS APPEAR TO EXERT INFLUENCES ON THE E REGION DYNAMO ELECTRIC FIELDS, THE EQUATORIAL ELECTROJET, AND PLASMA DRIFTS. OUR PURPOSE IN THE PROPOSED RESEARCH IS TO MORE CLEARLY DEFINE THE RELATIONS BETWEEN NEUTRAL AND PLASMA PERTURBATIONS AT VARIOUS ALTITUDES INDICATIVE OF NEUTRAL COUPLING FROM THE MESOSPHERE AND LOWER THERMOSPHERE (MLT) TO HIGHER ALTITUDES IN THE THERMOSPHERE AND FROM THE NEUTRAL ATMOSPHERE TO THE IONOSPHERE THROUGHOUT THE THERMOSPHERE-IONOSPHERE (TI) SYSTEM. THESE EFFORTS WILL SPECIFICALLY ADDRESS THE VARIOUS NEUTRAL ATMOSPHERE PERIODICITIES AND INFLUENCES (I.E., TIDES, PWS. GWS. AND SSWS) ALREADY OBSERVED TO IMPACT IONOSPHERIC DYNAMICS AT VARIOUS ALTITUDES. OUR RESEARCH WOULD EMPLOY EXISTING DATA FROM A NUMBER OF SATELLITES PERFORMING ROUTINE AND CORRELATIVE MEASUREMENTS OF NEUTRAL AND PLASMA FIELDSOUR ANALYSES WILL ALSO EMPLOY ADVANCED ASYNOPTIC SAMPLING METHODS SPECIFICALLY DEVELOPED FOR SINGLE- AND DUAL-SIDED VIEWING FROM SATELLITES IN PROCESSING AND/OR SUN-SYNCHRONOUS ORBITS FOR ALL OF OUR ANALYSES. WE ANTICIPATE THAT THESE ANALYSES WILL REVEAL RELATIONS BETWEEN THE NEUTRAL AND PLASMA FIELDS AT THE VARIOUS NEUTRAL ATMOSPHERE PERIODICITIES THAT WILL PROVIDE IMPORTANT CLUES TO THE COUPLING DYNAMICS OCCURRING WITHIN THE NEUTRAL ATMOSPHERE FROM LOWER TO HIGHER ALTITUDES, AND FROM THE NEUTRAL ATMOSPHERE TO THE IONOSPHERE AT HIGHER ALTITUDES.
