海冰密集度（SIC）是海冰导航、环境研究、天气和冰情预报的重要海冰参数。我们已经开发和测试的方法估计波罗的海SIC使用SENTINEL-1合成孔径雷达（SAR）和先进的微波扫描辐射计2无源微波辐射计（MWR）的数据。在这里，我们介绍了2016年1月的方法和结果。本文采用芬兰气象研究所日冰情图中的冰浓度格点作为参考资料。我们提出了四个SIC估计方法与我们的参考数据的比较。除了组合SAR/MWR SIC估计方法，我们还比较了SIC估计使用SAR单独和两个基于MWR的方法。本文的主要目标是开发和测试一个高分辨率的SIC估计方法，适用于业务使用。
Sea ice concentration (SIC) is an important sea ice parameter for sea ice navigation, environmental research, and weather and ice forecasting. We have developed and tested a method for estimation of the Baltic Sea SIC using SENTINEL-1 synthetic aperture radar (SAR) and Advanced Microwave Scanning Radiometer 2 passive microwave radiometer (MWR) data. Here, we present the method and results for January 2016. Ice concentration grids of Finnish Meteorological Institute daily ice charts have been used as reference data in this paper. We present a comparison of four SIC estimation methods with our reference data. In addition to the combined SAR/MWR SIC estimation method, we also compare SIC estimates produced using SAR alone and two MWR-based methods. The main target of this paper was to develop and test a high-resolution SIC estimation method suitable for operational use.
