Direct Broadcast Software, Products,Algorithms, Meetings
Software: IMAPP updatesand new features
Products: Realtime GeoTIFFfor ice monitoring
Algorithms: MODIS/AIRSretrievals, AMSR-Eprecipitation
Meetings: ITSC Beijing, Intl.EOS/NPP Benevento Aqua MODIS realtime TPW

Direct Broadcast Software: InternationalMODIS/AIRS Processing Package (IMAPP)
Current MODIS Level-2Algorithms:
Level 1Cloud MaskAtmospheric Profiles (T/q)Cloud Top Properties (IR)Aerosol Optical DepthSea Surface TemperatureNear-IR Water Vapor
These will all be updated toCollection 5 in 2005 Terra MODIS realtime AOD 2005/03/13

New MODIS Level 2 Algorithms for IMAPP
MODIS Level-2 Algorithms tobe ported to IMAPP:
Cloud Optical PropertiesLand Surface ReflectanceBRDFSnow/Ice Detection
These will all be ported andreleased in 2005

AIRS/AMSU/AMSR-E Software in IMAPP
Current Algorithms:Level 1B for AIRS/AMSULevel 1B for AMSR-E
In Development:AIRS/AMSU Level 2 RetrievalAMSR-E Precipitation
These will be released in2005
AMSR-E 89 GHz from 2003/09/03From SSEC DB

Realtime GeoTIFF products for the Great Lakes
Terra and Aqua MODIS 250meter true color images areproduced daily for each ofthe Great Lakes
GeoTIFF format in UTMprojection (GIS compatible)
NOAA Coastwatch, NationalIce Center, and Canadian IceService download the imagesin realtime

Algorithm Development
Aqua MODIS/AIRS:Synergistic retrievalalgorithm has beendeveloped
AMSR-E: Precipitation andsoil moisture algorithmshave been ported fromofficial versions
These algorithms will bereleased in IMAPP in 2005
