CIMR L2 SIC, SIED, and SIC1H ATBD

This document describes the algorithm theoretical basis for three closely related CIMR Level-2 products:

1. the nominal Sea Ice Concentration (SIC) Level-2 product (SIC3H);

2. the nominal Sea Ice Edge (SIED) Level-2 product (SIED);

3. the Sea Ice Concentration (SIC) Level-2 product with Near Real Time 1H latency requirement.

At this stage, these three products are documented in a single document because they share a large fraction of justification, approach, and software prototype code. For example, the SIED product is derived from the SIC product. This can be reconsidered at a later stage.
