19 channel microwave radiometer sensing in oxygen and water vapour bands.
This radiometer is comparable to MWS on EPS-SG/Metop-SG with a similar performance and the same as the radiometer on the Arctic Weather Satellite.
Cross-track scanning, swath 1870 km (±54.4o) covering the polar zones with no gap. Scan rate 45 rpm.
