This figure shows the simulated CIMR sea ice concentration field, using the Bristol algorithm as an example. The Bristol algorithm (Smith, 1996) combines brigthness temperature observations of the Ku (18.7 GHz) and Ka (36.5 GHz) channels.
Below, the CIMR simulated sea-ice concentration is compared to that of past and current passive microwave satellite sensors including the Scanning Multichannel Microwave Radiometer (SMMR, 1978-1987), the Special Sensor Microwave/Imager (SSM/I and SSMIS, 1987 - today), and JAXA's AMSR2 (2012-today). The reference Marginal Ice Zone (MIZ) image is from Moderate-Resolution Imaging Spectroradiometer (MODIS).
