OpenADDE Access to Data at Direct Broadcast Sites David Santek University of Wisconsin-Madison

Overview Internet access through client/server software Not ftp Not broadcast: data available on demand Data access to MODIS Level 1b, Level 2 products, AIRS Level 1b, AMSR-E Remote sites

McIDAS Man computer Interactive Data Access System Meteorological data visualization system Developed 30 years ago to track clouds from the new geostationary satellites Users worldwide Integrates many type of meteorological data ADDE servers are used for data access

ADDE Servers Abstract Data Distribution Environment In use for nearly 10 years Sectorizing of geographic coverage and bands [browse of 1 band is 2% of total file] Compressed transmission Private TCP/IP through registered port 112 Variety of clients can access the servers All data returned in common format: not the stored format.

ADDE Servers McIDAS format: Image, grid, point, text netCDF as grid and point HDF as point MODIS Level 1b and products as images AIRS Level 1b AMSR-E Level 1b Radar Meteosat 8 [MSG] Grib
