Summary
Abstract:
MODIS was launched aboard the Aqua satellite on May 04, 2002 (1:30 pm 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.
MYD08_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 MYD08_E3 and the principal investigators for this
product are MODIS scientists: Dr. Yoram Kaufman
(kaufman@climate.gsfc.nasa.gov) 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 (MYD08_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 (MYD08_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.
MYD08_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. For browsing and extracting data
from these files, some software are made available at the site.

are available from the MYD08_E3 web site.
The MODIS Eight-Day Product will be used in the simultaneous 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.

Quality
Slope and elevation accuracy of the DEMs is best near the latitudinal limit of satellite coverage (±86°), and provides a good representation of the ice sheet and mountain areas (based on comparison with satellite images). DEM accuracy decreases as track spacing between ICESat profiles increases equatorward. As a quality and accuracy indicator, the mean distance of all contributing GLAS surface spot data to the grid cell center was recorded in a separate identical grid for each ice sheet. These mean distance files are provided with the elevation data.
