Presentation Transcript

  1. MODIS Atmosphere Group Summary • Collection 5 Status • Summary of modifications and enhancements in collection 5 (mostly covered in posters) • Ready to commence in early April • Identified enhancements identified for collection 6 • Data Use/Validation Investigations • 25 presentations • New uses of MODIS data • Direct Broadcast • Exploding use of MODIS data worldwide • New software planned for AIRS and MODIS data this year

  2. Collection 5 Software Updates • All Software has been delivered to SDST/MODAPS • Science test 4 completed Monday • Major enhancements in cloud mask (especially nighttime and polar regions) • Cloud product uses new ice crystal libraries, better phase determination, atmosphere/land surface reflectance product, improved atmospheric correction, uncertainties in cloud optical thickness, effective radius, and water path, and improved cloud top pressure (especially for low clouds) • Aerosol product uses new spatial variability to improve screening of heavy aerosol and clouds, better regional characterization of aerosol optical properties • Water vapor over high dry regions, like Tibet, improved in near-infrared algorithm • Collection 6 enhancements identified for aerosol, including new Deep Blue algorithm for bright desert regions

  5. Miscellaneous Progress • Direct Broadcast exploding internationally • New software at Wisconsin will incorporate MODIS cloud, snow, reflectance, and BRDF products, AMSR-E precip, and high resolution AIRS/MODIS analysis in 2005 • Kenya has a direct broadcast receiving station in Malindi • Data received on ground and sent by tape to Rome • Unknown facility by NASA or Wisconsin/IMAPP group • Applications • IDEA project (NOAA/NASA/EPA) use of MODIS data and PM2.5 to input into air quality monitoring in US • MODIS polar winds being used by ECMWF, GMAO, NCEP (June), Japan, and Canada • Modeling activities • Several data assimilation and modeling investigations described that are showing great progress
