Summary: | Sea ice concentration is important because it helps in determining important climate variables. Together with sea ice thickness, important fluxes between air and sea as well as heat transfer between the atmosphere can be determined. We designed an adapted bootstrap algorithm called SARAL/AltiKa Sea Ice Algorithm (SSIA) with some tunings and segregated the algorithm into winter and summer algorithms to estimate daily sea ice concentration (SIC) in the Arctic. Brightness temperature data from the dual-frequency microwave radiometer (23.8 GHz and 37 GHz) onboard the SARAL/AltiKa satellite for the period April 2013 to December 2020 are used to estimate SIC. We compare our product with the daily National Snow Ice and Data Centre Climate Data Record (NSIDC CDR)SIC, the Ocean and Sea Ice Satellite Application Facility (OSISAF) SIC, and the ARTIST Sea Ice Algorithm SIC (ASI) and results show that our sea ice concentration is of good quality and can be used as a basic dataset for SIC records. ... |
