Shared Processing Program SSM/I Processing

 The US Air Force, US Navy, and NOAA participate in a interagency program referred to as the Shared Processing Program (SPP). The term "Shared Processing" has been applied to the sharing of data, products and associated information derived from the polar environmental satellite programs of the DOD's Defense Meteorological Satellite Program (DMSP), and NOAA's Polar Operational Environmental Satellite (POES) program.

NESDIS ingests and makes available a variety of Shared Processing data. Detailed descriptions of the content and format of that data are found below. The image products shown below use data from the last 14 polar orbits of the DMSP satellites, F13, F14 and F15 (which cover a time period of about 24 hours). The areas shaded gray represent either data gaps or indeterminate data. The data gaps (diamond-shaped) result from incomplete satellite coverage, and the indeterminate data (described for each product below) results from the inability to do retrievals over certain surface types.

For another resource and a more detailed explanation of the SSM/I products, please see the NESDIS
Microwave Sensing Group Team Page.  If you are interested in obtaining future
DMSP F16 data please see our Information Bulletin.
