This map, made using the Compact Ocean Wind Vector Radiometer (COWVR) instrument's observations from Jan. 16 to 23, 2022, shows Earth's microwave emissions at a frequency of 34 gigahertz. This frequency provides information on the strength of winds at the ocean surface, the amount of water in clouds, and the amount of water vapor in the atmosphere. Green and white indicate higher water vapor and clouds, while dark blue over the ocean indicates drier air and clear sky. Typical weather patterns for January, such as tropical moisture and rain (the green band stretching across the center of the map), are visible.

Designed and built at NASA's Jet Propulsion Laboratory in Southern California, COWVR is a technology demonstration aboard the International Space Station.
