中文摘要: 以EOS卫星的中分辨率成像光谱仪MODIS遥感资料为数据源,以福建近岸海域为示范区,利用
多通道数据算法模型进行近海海表温度卫星遥感反演试验,并根据2003—2004年福建近岸海
域10个观测站点的实测海洋表面温度对反演结果进行精度检验与分析。遥感反演的海洋表面
温度与现场观测的海洋表面温度绝对误差的平均值为0.75℃,标准差为0.52℃,绝对误差在
1.0℃以内的样本占总样本的68%。结果表明利用MODIS多通道数据算法模型遥感反演近海海
表温度能够满足海洋应用的精度要求。
Abstract:By using MODIS images of EOS satellite as data source,and taking coas
tal region of Fujian as a demonstration site, the retrieval experiment of sea su
rface temperature was carried out based on MODIS multi channel data,and the pr
e
cision of MODIS sea surface temperature was verified and analyzed with measureme
nts of ten stations in coastal region of Fujian during 2003-2004. The average ab
solute error of sea surface temperature calculated by MODIS data was 0.75℃
,the
standard error was 0.52℃,the samples of absolute error within 1.0℃ was 68% o
f total samples. The results showed that the accuracy of sea surface temperature
calculated by MODIS data in coastal region was equivalent with the accuracy of
sea surface temperature calculated by NOAA/AVHRR data.
