  8. CERES Goals • Obtain accurate measurements of fluxes of outgoing radiation at the top of the atmosphere. • Shortwave radiation • Total radiation • Longwave radiation • Radiation in the 8-12 m atmospheric window. • Derive improved values for the Earth’s radiation budget. • Analyze clouds and their effects on climate, using CERES and MODIS data. • Analyze the diurnal cycle of radiation fluxes, using the CERES data from Terra and Aqua. • Obtain and analyze long-term climate records using data from the Earth Radiation Budget Experiment (ERBE) and the CERES on TRMM, Terra, and Aqua.

  17. Aqua MODIS Goals • Examine a large variety of biological and physical processes, through generation and analysis of most of the same products as from the Terra MODIS. • Add a new Surface Evaporation Index. • Generate improved SSTs, benefiting from a gain change made to the Aqua MODIS bands 31 and 32 in October 2000. • Examine the diurnal cycle of many variables, using the Terra and Aqua MODIS data.

  25. Global Sea Ice Coverage June 2-4, 2002 (top) and July 21-22, 2002 (bottom) from AMSR-E (images courtesy of NASDA)

  26. AMSR-E Goals • Extend the records of many variables from previous passive-microwave instruments, with improved spatial resolution, and analyze the results. • Add records of soil moisture and surface temperatures. Sample record to be extended: a 20+-year satellite record of Arctic sea ice coverage (extended from Parkinson et al., 1999)

  27. Summary • Like AIRS, AMSU, and HSB, the other three Earth-observing instruments on Aqua (CERES, MODIS, and AMSR-E) are also sending down high quality data. • Like the AIRS Team, the CERES, MODIS, and AMSR-E Teams have also generated first light images from their instruments. • A series of press releases and image advisories based on Aqua data has begun. • AMSR-E press release, June 24. • CERES image advisory, July 31. • AIRS/AMSU/HSB press release, August 6. • MODIS press release, August 15. • AMSR-E image advisory, August 28.
