  1. Atmosphere Discipline Summary July 2002

  2. Recent progress Algorithm stabilization / product validation cloud mask, TPW, O3, CTH, aerosol cloud properties Publications 5 papers submitted to IEEE TGRS Aqua Issue papers in JGR, Nature, JAS Crystal field experiment ice cloud investigations

  3. Detecting cloud shadows over land by comparing observed 1.6um reflectance with 8-day clear-sky composite and looking for values lower than an 80% threshold

  4. Detecting cloud shadows over land by comparing observed 1.6um reflectance with 8-day clear-sky composite and looking for values lower than an 80% threshold

  5. Recent progress S/W updates to accommodate Aqua data initial product flow looks good Aqua concerns near real time geo-location (missing position sensor) - polar winds offset between warm-cold focal planes - TPW missing 1.6 um - cloud optical properties

  6. Terra and Aqua East African Scene from July 11, 2002 Terra at 08:05 UTC, Aqua from 11:00 UTC MODIS Band 2 Terra (left) and Aqua (right) MODIS Cloud Mask Terra (left) and Aqua (right) Colors: green is confident clear cyan is probably clear red is uncertain white is cloudy

  7. Terra and Aqua East African Scene from July 11, 2002 Terra at 08:05 UTC, Aqua from 11:00 UTC MODIS Band 31 Terra (left) and Aqua (right) MODIS Cloud Top Pressure (mb) Terra (left) and Aqua (right) Colors: red  100 aqua 400-500 white 100-200 tan 500-700 cyan 200-300 brown 700-850 blue 300-400 orange 850-1000 gray is clear

  8. Atmospheric Total Column Water VaporEast African Scene from July 11, 2002Terra at 08:05 UTC, Aqua from 11:00 UTC Terra 08:05 UTC Aqua 11:00 UTC

  9. Global Atmospheric Total Column Water Vapor Terra cm 5 July 2002 Aqua cm

  10. SRF Terra (solid) and Aqua (dashed)

  11. Near Term Plans Global IR radiance bias (obs – calc) adjustment sequencing of 8 day clear sky composite forward stream as well as reprocessing Level 3 Products animation for easier QC intercomparison of complementary TPWs, etc. ATBD updates by end of Sep 2002 algorithm evolution Aqua adjustments quality indicators IR Calibration in Nov 2002 MAS and SHIS underfly of Aqua

  12. Terra plus Aqua Better Polar Winds Diurnal process studies aerosol, moisture, and clouds AIRS plus MODIS cloud properties soundings
