ASI3 algorithm: sea ice concentration retrieval based on weather-corrected 89GHz data

An improved method to estimate sea ice concentration from 89 GHz brightness temperature data. Purpose: 1.Applies weather correction on the AMSR-E brightness temperatures through a radiative transfer model. 2.Retrieves sea ice concentration from the weather-corrected 89 GHz brightness temperatures. Input data: 1. AMSR-E Level 2A brightness temperatures. 2. Geophysical parameters (total water vapor, cloud liquid water, wind speed, surface temperature) retrieved by an optimal estimation method (Scarlat 2017). Output data: 1. Weather corrected brightness temperatures. 2. Sea ice concentration.
