This product is best suited for a cal/val user or sensor expert. It includes one month of satellite-based observations of calibrated, geo-located antenna temperature and brightness temperatures, along with the sensor telemetry used to derive those values. Brightness temperatures are derived from the microwave band frequencies 18.7 GHz, 23.8 GHz, and 34.5 GHz. These level 1c measurements are from the COWVR (Compact Ocean Wind Vector Radiometer) sensor aboard the international space station (ISS) during a one-month period where the instrument was rotated into an off-nominal orientation to sample the Earth over all observation angles to inform future science/instrument design. Data files in HDF5 format are available at roughly hourly frequency (the ISS orbit period is ~90 minutes) and provide non-gridded data over the satellite swath. Files include calibration and flag data in addition to brightness temperatures.

The COWVR sensor is a fully polarimetric, conically imaging microwave radiometer for measuring ocean surface wind vectors. It operates nominally on-orbit aboard the ISS and data are non-sun-synchronous. It was deployed as 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.
