BackForwardInstrument:  AMR-C 

Instrument details
Acronym AMR-C
Full name Advanced Microwave Radiometer - C
Purpose Water vapour correction for the JASON-CS radar altimeter (SRAL)
Short description 3-frequencies:18.7, 23.8 and 34 GHz. An experimental high-frequency component, HRMR, for high resolution support to the SAR mode of SRAL has been added. Frequencies: 90, 130 and 168 GHz.
Background Evolution of the AMR flown on JASON 2 and 3
Scanning Technique Nadir-only viewing, associated to the Sentinel-6 radar altimeter (Poseidon-4)
Resolution 25 km for the basic AMR frequencies. 3-5 km for the experimental high-resolution component
Coverage / Cycle Global coverage in 1 month for 30 km average spacing, or in 10 days for 100 km average spacing
Mass Power Data Rate
