The Compact Ocean Wind Vector Radiometer (COWVR) was developed at the Jet Propulsion Laboratory and is installed on the International Space Station, where it has been collecting measurements since January 2022. COWVR performs conical imaging at three frequencies (18.7, 23.8, and 33.9 GHz) with six full polarizations for each frequency, providing a total of eighteen channels. The instrument aims to demonstrate new low-cost microwave sensor technologies for weather applications.
