COWVR STP-H8 Antenna and Microwave Brightness Temperatures Version 11
Listed in NASA Earthdata CMR
This dataset includes satellite-based observations of calibrated, geo-located antenna temperature and brightness temperatures, along with the sensor telemetry used to derive those values.
Description
This product is best suited for a cal/val user or sensor expert. These level 1c measurements are from the COWVR (Compact Ocean Wind Vector Radiometer) sensor aboard the international space station (ISS).
COWVR operates in the microwave band, at frequencies 18.7 GHz, 23.8 GHz, and 34.5 GHz. Its swath width is 1012 km and spatial resolution is <35 km. Data files (HDF5 format) roughly cover one orbit each (the ISS orbit period is ~90 minutes) and provide non-gridded data over the satellite swath.

The files also include calibration and flag data. This deployment of the COWVR instrument was part of the Space Test Program - Houston 8 (STP-H8) technology demonstration mission. COWVR was provided by the Jet Propulsion Laboratory and flown by the United States Space Force, Space Systems Command, Development Corps for Innovation and Prototyping.
