基于风云三号系列卫星数据的北极海冰密集度反演产品的对比分析
Comparative analysis of Arctic sea ice concentration retrieval products based on Fengyun-3 series satellite data
摘要
Abstract
This study compared multisatellite composite sea ice concentration(SIC)data(the FY-3 dataset)re-trieved by China's National Satellite Meteorological Center's Fengyun-3 series satellites(FY-3B,FY-3C,and FY-3D),with 0.25° daily SIC data(the OISST dataset)provided by the National Oceanic and Atmos-pheric Administration,and SIC data from MASAM2(the MASAM2 dataset)and SSMIS(the SSMIS dataset)provided by the National Snow and Ice Data Center.Analysis of these datasets revealed the following.(1)The average root mean square error(ERMSE)for the FY-3,OISST,and MASAM2 datasets in the Atlantic sector is 0.15,0.13,and 0.13,respectively;in the Pacific sector,the average ERMSE is 0.13,0.11,and 0.12,respectively.The main difference is overestimation of September SIC in the FY-3 dataset.(2)The deviation in sea ice extent in the FY-3 dataset is lower than that of the OISST dataset throughout the entire period and lower than that of the MASAM2 dataset after 2016,with a minimum mean absolute percentage error of 2.5%.In terms of marginal ice zone extent,the FY-3 and MASAM2 datasets both exhibit substantial underestima-tion(normalized mean bias:45%)in the Pacific sector.(3)Comprehensive comparison revealed that the quality of the FY-3 dataset is comparable with that of the OISST dataset,but that some discrepancies are evident relative to the MASAM2 dataset,especially for long-term sequence retrieval products.Therefore,it is recommended that research and development efforts be focused on eliminating data inconsistencies among satellite retrievals.关键词
