In a recent paper, two operational algorithms to derive ice concentration from satellite multichannel passive microwave sensors have been compared. Although the results of these, known as the NASA Team algorithm and the Bootstrap algorithm, have been validated and are generally in good agreement, there are areas where the ice concentrations differ, by up to 30%. These differences can be explained by shortcomings in one or the other algorithm. Here, we present an algorithm which, in addition to the 19 and 37 GHz channels used by both the Bootstrap and NASA Team algorithms, makes use of the 85 GHz channels as well. Atmospheric effects particularly at 85 GHz are reduced by using a forward atmospheric radiative transfer model. Comparisons with the NASA Team and Bootstrap algorithm show that the individual shortcomings of these algorithms are not apparent in this new approach. The results further show better quantitative agreement with ice concentrations derived from NOAA AVHRR infrared data.

Ice charts from the U.S. National Ice Center are used to evaluate published algorithms for generating sea-ice concentrations from SSM/I data. The same ice charts, in a form that includes information derived from RADARSAT, OLS and AVHRR data, are used in an operational algorithm that effectively tunes a hybrid of the Bootstrap and NASA team algorithms and principal components of the SSM/I data to the time and region associated with the ice chart. This "tuned" algorithm is then used to interpolate ice concentrations elsewhere in the ice chart where no cloud-free, high resolution visible, infrared or active microwave satellite data are available. The algorithm is designed to operate in near real time to assist the ice analysts in their otherwise manually-intensive task of coupling ice charts for vessels operation in ice infested waters.
