MODIS/Aqua Surface Reflectance Daily L3 Global 0.05Deg CMG V004Entry ID: MYD09CMG4
Abstract: This Version 004 MODIS product is decommissioned.
The Surface Reflectance Climate Modeling Grid product (MYD09CMG) provides a
regular view of the entire globe in a projection useful for climate modeling
The MYD09CMG product is estimated on a 0.05 degree grid daily using MODIS
... Level-1B Bands 1-7 (459-2155nm) for each Band as it would be measured at ground
level, if there were no atmospheric scattering or absorption. The correction
scheme accounts for the effects of atmospheric gases, aerosols, and thin cirrus
clouds; it is applied to all Level-1B pixels that pass the Level-1B quality
control. The correction uses Band 26 to detect cirrus clouds (the approach used
in MYD04 and MYD05 for water vapor, aerosol correction) and NCEP for ozone; the
best available climatology data are used if the MODIS water vapor, aerosol, or
ozone products are unavailable.
