This site provides software, documentation and data for a Fundamental Climate Data Record (FCDR) of microwave imager brightness temperatures including SSM/I from 1987 to the present and its successor, SSMIS, from 2005 to the present. This record of passive microwave measurements is expected to continue well into the future to provide long-term global observations for climate applications. Additional information
OverviewOverview: The definition, goals, and anticiplated user communities
Motivation: Why having a transparent, well-documented process is as important as producing an intercalibrated dataset
Data Availability: The time range of currently available data from all of the SSM/I and SSMIS sensors
Approach: A description of the intercalibration methods and data processing flow
Validation: Time series of geophysical products
SSM/IDescription: Specifications for the Special Sensor Microwave/Imager and DMSP spacecraft
