Sea-Ice Concentration
Measurement Instruments
Measurement Definition: The ocean area fraction of a cell covered by sea ice.
| Instrument | Status/
Accuracy | Instrument Description | Measurement Technology | Timeline |
| SGR-ReSI-CDHS | Operational | Ocean winds, waves, soil moisture, flooding, ice, snow. Similar to SGR-ReSI-Z, but with a smaller Zynq, and only supports 2 RF channels, only allowing collection of single frequency and single polarisation. | n/a |  |
| Imaging Microwave Radiometer | Being developed | A conical scanning total power radiometer operating in 5 bands (L/C/X/K/Ka) to provide high-spatial resolution microwave imaging radiometry measurements and derived products with continuous global coverage and sub-daily revisit in the polar regions and adjacent seas. | n/a | |
| MWI | Being developed | Measure cloud liquid water content, solid/liquid precipitation information, total column water vapour and temperature profiles, sea ice parameters, sea surface temperature, sea surface wind speed. | n/a | |
| SGR-ReSI-Z | Being developed | Ocean winds, waves, soil moisture, flooding, ice, snow | n/a | |
