Index A | B | C | E | I | M | P | S | T A ATBD B Brightness Temperature C CIMR Copernicus Imaging Microwave Radiometer E EASE2 Equal area projection grid definition based on a Lambert Azimuthal projection and a WGS84 datum. Defined in brodzik:2012:ease2. Equal Area Scalable Earth v2 I IODD M MRC P PSD PVP S Sea Ice Concentration Sea Ice Drift Sea Ice Motion Sea Ice Motion and Sea Ice Drift are used interchangeably to characterize the horizontal motion of sea ice above the ocean. It is at minimum described by a vector. SIC T TB The Brightness Temperature is the temperature of a surface as seen by a passive microwave sensor. It is a measure of the amount of energy emitted by a surface. It is usually expressed in Kelvin. The Copernicus Imaging Microwave Radiometer is a Microwave Radiometer which launch is planned by ESA in 2028. 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.
