  • Improved Stratospheric And Mesospheric Sounder via WWW

    https://cmr.earthdata.nasa.gov/search/concepts/C1214600477-SCIOPS.xml
    Description:

    The ISAMS home page on the WWW is "http://www.atm.ox.ac.uk/main/". The UARS satellite is in an orbit inclined at 57 degrees (?TBD) to the equator, and which precesses 5 degrees longitude per day relative to the sun. Thus, for one day's data, local solar time around each orbit is an approximately constant function of latitude (differing by 12 hours for ascending and descending nodes) but over a period of 72 days the entire diurnal cycle is sampled at each latitude. Thermal stability requires that one side of the satellite (+Y) is never illuminated by the sun. To maintain this situation in an orbit that precesses relative to the sun (i.e. not sun-synchronous), the satellite has to be yawed through 180 degrees approximately every 36 days. ISAMS is a limb sounder, which, at the satellite altitude of 600km (?TBD), places the tangent point at 23 degrees from the orbital track. When the satellite flies in the +X direction (defined as forwards), viewing to the (usual) anti-sun side (+Y) gives coverage from 80N to 34S. Conversely, when the satellite yaws to fly in the -X direction (backwards), the coverage viewing to +Y is from 34N to 80S. ISAMS also has the ability, when the sun-satellite geometry is favourable, to view to the -Y side for parts of orbits, increasing the potential coverage to 80N-80S for either satellite flight direction. Spectral selection is achieved by pressure-modulator cells (PMCs) (Taylor, 1983) whose pressures, therefore transmission characteristics, may be altered in flight. The various observing geometries, plus the ability to program the scan pattern and PMC pressures, lead to a large number of operating modes for ISAMS, which may be characterised by some combination of: (1) PMC Cell Pressure in each of the 8 Cells (2) Anti-Sun/Sun side viewing (+/- Y side of spacecraft) (3) Satellite Direction (+/- X direction of motion) (4) Day/Night at tangent point (5) Ascending/Descending node (6) Limb Scan program Whether the tangent point is illuminated or not does not affect the operation of the ISAMS instrument, but it is convenient to add it to this list.

  • Photochemistry of Ozone Loss in the Arctic Region In Summer (POLARIS) Data Archive

    https://cmr.earthdata.nasa.gov/search/concepts/C1214613359-SCIOPS.xml
    Description:

    POLARIS was a series of high-altitude airborne investigations to understand the behavior of polar stratospheric ozone as it changes from very high concentrations in the spring down to very low concentrations in autumn. The data will help with our understanding on the distribution, chemistry, and physics of stratospheric ozone after the vortex breakup, during the continuous daylight conditions of summer. The experiment took place during April - September 1997 from Fairbanks, Alaska. A complete summary of the results of the experiment are available from: http://espoarchive.nasa.gov/archive/arcs/polaris/docs/eoms/

  • SAGE III Ozone Loss and Validation Experiment (SOLVE)

    https://cmr.earthdata.nasa.gov/search/concepts/C1214613235-SCIOPS.xml
    Description:

    The SAGE III Ozone Loss and Validation Experiment (SOLVE) is a measurement campaign designed to examine the processes which control polar to mid-latitude stratospheric ozone levels. SOLVE is an Arctic mission which was conducted over the course of the 1999-2000 winter. SOLVE employed aircraft, satellites, and balloons to examine the processes which control polar to mid-latitude stratospheric ozone levels. The mission also acquired correlative measurements needed to validate the Stratospheric Aerosol and Gas Experiment (SAGE) III satellite mission and used these satellite measurements to help quantitatively assess high latitude ozone loss.

  • SOLVE I Supplementary Satellite Data Products

    https://cmr.earthdata.nasa.gov/search/concepts/C2569836885-LARC_ASDC.xml
    Description:

    SOLVE1_Satellite_Data is the supplementary satellite data for the SAGE III Ozone Loss and Validation Experiment (SOLVE). Data were collected by instruments such as the Halogen Occultation Experiment (HALOE), the Polar Ozone and Aerosol Measurement III (POAM III) satellite, and the Global Ozone Monitoring Experiment (GOME). Data collection for this product is complete. The SOLVE campaign was a NASA multi-program effort of the Upper Atmosphere Research Program (UARP), Atmospheric Effects of Aviation Project (AEAP), Atmospheric Chemistry Modeling and Analysis Program (ACMAP) and Earth Observing System (EOS) of NASA’s Earth Science Enterprise (ESE). SOLVE’s primary objective was for calibrating and validating the Stratospheric Aerosol and Gas Experiment (SAGE) III satellite measurements, while examining the processes that controlled ozone levels at a mid- to high-latitude range. The major goal of SAGE III was to quantitatively assess ozone loss at high latitudes. SOLVE was a two-phase experiment, the first phase, SOLVE, occurred during the fall of 1999 through the spring of 2000. The second phase, SOLVE II, occurred during the winter of 2003. SOLVE took place in the Arctic high-latitude region during the winter. The polar ozone depletion processes cause by human-produced chlorine and bromine are most active in mid-to-late winter and early spring in the high Arctic. In order to conduct this validation experiment, NASA deployed the NASA ER-2 aircraft and NASA DC-8 aircraft. The ER-2 measured a variety of atmospheric data, including ozone (O3), H2O, CO2, ClONO2, HCl, ClO/BrO, and Cl2O2. The DC-8 aircraft measured ozone, ClO/BrO, and aerosol, among other atmospheric data. SOLVE also utilized balloon platforms, ground-based instruments, and collaborations with the German Aerospace Center’s (DLR) FALCON aircraft equipped with the OLEX Lidar to achieve the mission objectives. Overall, the campaign had 28 flights, with SOLVE featuring 17 total flights among the different aircrafts and SOLVE II featuring 11 flights.
