2021-01-06 Sea Ice Concentration Products over Polar Regions with FY-3C/MWRI Data (2016-2019） doi:10.11922/sciencedb.00511 en Polar sea ice affects atmospheric and ocean circulation and plays an important role in global climate change. Long-time-series sea ice concentration is an important parameter for climate research. Sea ice concentration (SIC) products over the Antarctic and Arctic in 2016-2019 were supplied based on the brightness temperature (Tb) data of the FY-3C Microwave Radiation Imager (MWRI). With the Tb data of SSMIS as a reference, monthly calibration models were established based on time-space matching and linear regression. After calibration, the correlation coefficients between the BT of F17/SSMIS and FY-3C/MWRI at different channels were effectively improved. Atmospheric effects were reduced using two weather filters and a sea ice mask. A minimum ice concentration array used in the procedure reduced the land-to-ocean spillover effect. sea ice concentration; FY3C; MWRI; polar regions Lijian Shi PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
