南极海冰边界AMSR-E密集度产品精度检验
|
Abstract:
根据海冰船测目视观测标准在MODIS影像上提取模拟的海冰边界,并利用相应的MODIS海冰密集度验证AMSR-E海冰密集度产品在海冰边界的精度。研究结果表明,海冰边界像素上,AMSR-E海冰密集度的平均值与15%阈值存在显著差异,且AMSR-E与MODIS海冰密集度的相关性很弱(R2≤0.2),基于ASI的海冰反演算法在夏季低估边界海冰密集度。考虑整个冰区(包括多年冰、一年冰、新冰和开阔海域)的截线分析显示,AMSR-E与MODIS海冰密集度存在较好的线性关系(夏季R2=0.82,冬季R2=0.81),AMSR-E海冰密集度在20%~30%区间的误差最大
