| Measurement Definition*: The ocean area fraction of a cell covered by sea ice. |
Instrument | Status/ Accuracy | Instrument Description | Measurement Technology | Timeline |
SGR-ReSI-CDHS Space GNSS Receiver - Remote Sensing Instrument, CoreDHS avionics | 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 Imaging Microwave Radiometer | Being developed
| A conical scanning total power radiometer operating in 5 bands (L/C/X/Ku/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 Microwave Imager | 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 Space GNSS Receiver - Remote Sensing Instrument (Zynq based) | Being developed
| Ocean winds, waves, soil moisture, flooding, ice, snow | n/a | |
