Summary
Abstract: This is the MODIS/Aqua subset along the Microwave Limb Sounder (MLS) field of
view track. The goal of the subset is to select and return MODIS data that are
within +-100 km across the MLS track. I.e. the resultant MODIS subset swath is
about 200 km cross-track. Thus, MAM03S0 cross-track width is 201 pixels.
Along-track, all MODIS pixels from the original product are preserved.

In the standard product, geolocation fields are calculated for each 1 km MODIS
Instantaneous Field of Views (IFOV) for all orbits daily. The locations and
ancillary information corresponds to the intersection of the centers of each
IFOV from 10 detectors in an ideal 1 km band on the Earth's surface. A digital
terrain model is used to model the Earth's surface. The main inputs are the
spacecraft attitude and orbit, the instrument telemetry and the digital
elevation model. The geolocation fields include geodetic Latitude, Longitude,
surface height above geoid, solar zenith and azimuth angles, satellite zenith
and azimuth angles, and a land/sea mask for each 1 km sample. Additional
information is included in the header to enable the calculation of the
approximate location of the center of the detectors of any of the 36 MODIS
bands. This product is used as input by a large number of subsequent MODIS
products, particularly the products produced by the Land team.

Temporal Resolution:
"Two day repeat observations with a repeat orbit pattern every 16 days. The
have two observations per day."

(The shortname for this product is MAM03S0).
