15 16 17 Abstract 18 This paper reviews four commonly-used microwave radiative transfer models that take different 19 electromagnetic approaches to simulate snow brightness temperature (T B): the Dense Media The Canadian Ice Service Digital Archive (CISDA) is a compilation of weekly ice charts that cover Canadian Waters. The Canadian Ice Service Digital Archive (CIS-DA), a record of weekly ice charts, provides more detailed sea ice information and extends Canadian sea ice conditions as far back as 1960. In remaining Canadian waters, ice information is updated weekly from the regional charts which are issued at the end of the day every Wednesday. We look forward to providing the highest quality products and services for Great Lakes ice information this winter. [PDF - 937 KB], Seasonal Outlook Prior to the analysis, the quality of the data was assessed by first quantifying errors in the estimates of ice concentration and ice type, and then by identifying any potential bias in estimates by comparing the data with other sea ice data sets.
