The Copernicus Imaging Microwave Radiometer (CIMR) mission is dedicated to EU actions on safeguarding the Arctic and monitoring climate change as expressed by the EU Arctic Policy for a safe, stable, sustainable, peaceful and prosperous Arctic.
The mission has been designed to provide measurements that will provide decision makers with evidence of change and impact in the polar regions, with a focus on the Arctic in a global context. CIMR has a large rotating gold mesh antenna to conically scan Earth’s surface to return high-resolution measurements related to sea ice, the ocean, snow and ice-sheet surfaces, all with a sub-daily revisit in the Arctic region.
