Definitions used in this ATBD#

Here follows a glossary, or list of definitions

Brightness Temperature#: The Brightness Temperature is the temperature of a surface or gas as seen by a passive microwave sensor. It is a measure of the amount of energy emitted by the surface or gas. It is usually expressed in Kelvin.
Copernicus Imaging Microwave Radiometer#: The Copernicus Imaging Microwave Radiometer (CIMR) is a Microwave Radiometer which launch is planned by the EU and ESA in 2029.
DEVALGO#: CIMR DEVALGO is an ESA project to develop Level-2 algorithms for the CIMR satellite.
Moderate Resolution Imaging Spectroradiometer#: The Moderate Resolution Imaging Spectroradiometer (MODIS) is a key instrument aboard NASA’s Terra and Aqua satellites, providing high-resolution images of the Earth’s surface and atmosphere.
Sea Ice Concentration#: The Sea Ice Concentration is the fraction of the sea surface covered by sea ice. It is a measure of the amount of sea ice in a given area. It is usually expressed as a percentage.
Sea Ice Thickness#: The Sea Ice Thickness is the thickness of the sea ice. It is usually expressed in meters.
Soil Moisture Active/Passive#: The Soil Moisture Active/Passive (SMAP) is a Satellite based L-Band Radiometer launched by NASA in 2015.
Soil Moisture and Ocean Salinity#: The Soil Moisture and Ocean Salinity (SMOS) is a Satellite based L-Band Radiometer launched by ESA in 2009.
