Abstract
The Moderate Resolution Imaging Spectroradiometer (MODIS), a major NASA's Earth Observing System (EOS) instrument, was launched aboard the TERR satellite on December 18, 1999 (10:30 am equator crossing time) for global monitoring of the atmosphere, the terrestrial ecosystems and oceans. On May 4 this year a similar instrument was launched on the EOS-AQUA satellite (1:30 pm equator crossing time). This will enable scientists to study diurnal variation of the rapidly varying systems and will provide a long-term dataset for the same geophysical parameters for the study of climate and global change studies. MODIS with its 2330 km viewing swath width provides almost daily global coverage. It acquires data in 36 high spectral resolution bands between 0.415 and 14.235 micron with spatial resolutions of 250m (2 bands), 500 (5 bands), and 1000m (29 bands). The radiance data measured by MODIS at high spatial resolution with some new channels (never used before for the remote sensing) provides improved and valuable information about the physical structure of the Earth's atmosphere and surface MODIS raw radiance counts, onboard calibrators data, geolocation products, radiometric calibrated and geolocated calibrated radiance/reflectance, and all derived geophysical atmospheric and ocean products are archived at the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) Distributed Active Archive Center (DAAC). http://daac.gsfc.nasa.gov/. The MODIS Data Support Team (MDST) at the GES DISC DAAC continues to provide data support in accessing the scientific data, data visualization tools, and product related information to the earth science user community.
