The Weather System Follow-on—Microwave (WSF-M) is the Department of the Defense’s (DoD) next-generation operational environmental satellite system. WSF-M will provide accurate, actionable environmental intelligence, supporting military operations.

WEATHER SYSTEM FOLLOW-ON —MICROWAVE

GO BEYOND WITH BALL.®

WSF-M is the DoD’s newest program of record to address critical space-based environmental monitoring (SBEM) requirements, providing the warfighter with critical environmental intelligence. The WSF-M mission was designed to specifically address three critical SBEM gaps: ocean surface vector winds (OSVWs), tropical cyclone intensity (TCI), and LEO energetic charged particle characterization, a space weather gap. In addition, the design characteristics of the WSF-M microwave sensor, which includes a large 1.8 meter antenna, will enable mitigation of other SBEM gaps, including sea ice characterization, soil moisture and snow depth.The WSF-M primary payload is a passive microwave radiometer, a sensor with a long history of making critical measurements of the physical properties of the atmosphere, ocean and land surface and used by multiple agencies, including Air Force, Navy and NOAA. The DoD has flown passive microwave sensors for decades, including the Defense Meteorological Satellite Program’s (DMSP) Special Sensor Microwave Imager/Sounder (SSMI/S) and the Navy Research Laboratory’s WindSat sensors.
