Observations by Multi-channel Scanning Microwave Radiometer (MSMR) for a period of one year are studied using the data collected by IRS-P4 over polar region. It is demonstrated that analysis by passive radiometer is very helpful for monitoring temporal and spatial variation of complex sea-ice cover....
