MODIS atmospheric data products at the Goddard Earth Sciences DAAC

The Goddard Earth Science (GES) Distributed Active Archive Center (DAAC), an integral part of the Earth Observing System Data and Information System (EOSDIS), is the official source of Moderate Resolution Imaging Spectroradiometer (MODIS) atmospheric data products for the science community. The MODIS instrument was launched in December 1999 onboard the Terra (formally AM-1) spacecraft and the GES DAAC has been successfully ingesting, processing, archiving, and distributing MODIS data since February 24, 2000. These measurements provide unique and much needed data for the atmospheric research and applications communities. The GES DAAC archives approximately 500 gigabytes (GB) of MODIS data per day. The full suite of atmosphere products is archived at the NASA GES DAAC at a rate of about 40 GB/day. A significant increase in the volume of atmospheric data being ingested, archived and distributed at the GES DAAC will occur when the MODIS instrument onboard the Aqua (formally PM-1) spacecraft begins transmission. The data are distributed to the community through a combination of EOS Data Gateways, the GES DAAC Search and Order World Wide Web (WWW) interface and an FTP site that contains samples of MODIS data. The MODIS Data Support Team (MDST) provides expert assistance to assist the users to turn data into information. The MDST Website is at http://daac.gsfc.nasa.gov/CAMPAIGN DOCS/MODIS/index.shtml.
