This page provides access to various documents pertaining to MODAPS
production and LAADS archive and distribution:
MODAPS has started Collection 5 reprocessing and forward processing for Aqua
atmospheres and will start Collection 5 land reprocessing for Terra on
June 5, 2006. Complete plans are given for these disciplines at
Collection 5 Atmospheres Reprocessing Plan
Collection 5 Land Reprocessing Plan.
MODAPS submits routine reports to the weekly PI Processing (PIP) group
meetings. These reports including summaries of MODAPS forward and
reprocessing production plans and actuals, and the status of GES DAAC/MODAPS
Current and historical reports are available at
MODIS Distribution Reports
This page provides information on the amount of data provided to MODIS
users. The reports included monthly averages and daily totals in both
volume and number of files.
MODIS Algorithm Theoretical Basis Documents
The Algorithm Theoretical Basis Documents (ATBDs) provide the mathematical
and theoretical bases for the algorithms used in MODIS processing. (This
link will open in a new browser window).
MODAPS will perform reprocessing for the atmospheres and land disciplines
using L0 data as input. These data are currently archived on disk in
MODAPS. Since the GES DAAC has also reprocessed some Collection 5 L1 and
cloud mask/profiles and is currently distributing these data products, it
is important to establish the GDAAC- and MODAPS- generated products are
equivalent. A total of 27 "comparison days" have been identified (17 for
Terra and 10 for Aqua) and detailed studies of the GDAAC and MODAPS values
have been conducted. The study indicates that the two data sets are
equivalent for reprocessing and forward processing purposes. The
inter-comparison report is available.
