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.
MOD08_M3 is a level-3 MODIS gridded atmosphere monthly global joint
product. It contains monthly 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 monthly global product is
MOD08_M3 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 monthly global product (MOD08_M3) consists of
approximately 739 parameters that includes all statistically derived
quantities. Essentially all level-3 MODIS atmosphere monthly 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 a (calendar) monthly
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_M3 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 monthly 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.
