Abstract:
MODIS was launched aboard the Terra satellite on December 18, 1999 (10:30 am equator crossing time) as part of NASA's Earth Observing System (EOS) mission. 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 to 14.235 micron with ... spatial resolutions of 250m(2 bands), 500m(5 bands), and 1000m (29 bands). MODIS sensor counts, calibrated radiances, geolocation products and all derived geophysical atmospheric and ocean products are archived at NASA Goddard DAAC and has been made available to public since April 2000.
MOD08_E3 is a level-3 MODIS gridded atmosphere eigh-day global joint product. It contains eight days 1 x 1 degree grid average values of atmospheric parameters related to atmospheric aerosol particle properties, total ozone burden, atmospheric water vapor, cloud optical and physical properties, and atmospheric stability indices. This product also provides standard deviations, quality assurance weighted means and other statistically derived quantities for each parameter.
The shortname for this level-3 MODIS atmosphere eight-day global product is MOD08_E3 and the principal investigators for this product are MODIS scientists: Dr. Yoram Kaufman for aerosol retrieval over land; Dr. Didier Tanre (didier.tanre@univ-lille1.fr) for aerosol retrieval over ocean; Dr. Bo-Cai Gao (gao@rsd.nrl.navy.mil) for cirrus cloud detection; Dr. Paul Menzel (paulm@ssec.wisc.edu) for cloud top properties; and Dr. Michael King (king@climate.gsfc.nasa.gov) for cloud optical properties.
The level-3 atmosphere eight-day global product (MOD08_E3) consists of approximately 739 parameters that includes all statistically derived quantities. Essentially all level-3 MODIS atmosphere eight-day global parameters are derived from the scientific parameters of MODIS Atmosphere Daily Global Joint Product (MOD08_D3). Statistics are computed over a 1 degree equal-angle lat-lon grid that spans an 8-day interval. It should be noted that the eight-day intervals are not reset at the beginning of a new month or a new year. Since the grid cells are 1 degree by 1 degree, the output grid is always 360 pixels in width and 180 pixels in length.
MOD08_E3 product files are stored in Hierarchical Data Format (HDF-EOS). Each gridded global parameter is stored as Scientific Data Sets (SDS) within the file.

The MODIS Eight-Day Product will be used in the simultaneously study of clouds, water vapor, aerosol , trace gases, land surface and oceanic properties, as well as the interaction between them and their effect on the Earth's energy budget and climate. This product will also be used to investigate seasonal and inter-annual changes in cirrus (semi-transparent) global cloud cover and cloud phase with multispectral observations at high spatial resolution.

-------------------------------------
ODV(mp) is a multi-platform version of Ocean Data View. It is based on version 5.7 of the "classical" ODV and runs on Windows, UNIX, Linux and Mac OS-X systems. ODV(mp) provides platform-independence of collection and configuration files. Data collections and configuration files can be moved between platforms and there is no need for translation. ODV(mp) is backwards compatible to the "classical" ODV and supports your previous data collections and configuration files.
The "classical" ODV is still available (Windows platforms only).
