Summary

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.

This is a level-3 MODIS gridded atmosphere daily global joint product
'MOD08_D3'. It contains daily 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 daily global product
is MOD08_D3 and the principal investigator 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 daily global product (MOD08_D3) consists of
approximately 500 parameters that includes all statistically derived
quantities. Essentially all level-3 MODIS atmosphere daily global
parameters are derived from the four level-2 MODIS atmosphere products
MOD04_L2, MOD05_L2, MOD06_L2, and MOD07_L2. Statistics are computed
over a 1 degree equal-angle lat-lon grid that spans a 24-hour (0000 to
2400 Greenwich Mean Time) interval. 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_D3 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:
http://ladsweb.nascom.nasa.gov/tools/ .
