摘要
根据船测方法在MODIS影像上提取模拟船测海冰密集度,并与船测数据联合验证AMSR-E海冰密集度产品。结果表明,AMSR-E海冰密集度与模拟船测海冰密集度的一致性高于其与船测海冰密集度,且相同时间、相同尺度下的海冰密集度之间一致性较高,不同时间、相同尺度下的海冰密集度之间存在不同程度的差异。
According to the ASPeCt sea ice observation protocol,we extracted simulated SIC(SIC is short for sea ice concentration) from MODIS images and combined with ship data,assessed the quality of AMSR-E SIC products.Results show that the consistency between simulated SIC and AMSR-E SIC is higher than that of ship SIC and AMSR-E SIC.SICs under same time and scale have high consistency and show varying degrees of difference under same scale but different time.
