Validation of Satellite-Derived Sea Surface Temperatures for Waters around Taiwan

Blog Article

In order to validate the Advanced Very High Resolution Radiometer (AVHRR)-derived sea surface temperatures (SST) of the waters read more around Taiwan, we generated a match-up data set of 961 pairs, which included in situ SSTs and concurrent AVHRR measurements for the period of 1998 to 2002.Availability of cloud-free images, i.e., images with more than 85% of cloud-free area in their coverage, was about 2.23% of all AVHRR images during the study period.

The range of in situ SSTs was from _ to _ The satellite derived-SSTs through MCSST and NLSST algorithms were linearly related to the in situ SSTs with correlation coefficients of 0.985 and 0.98, respectively.The MCSSTs and NLSSTs had small biases of 0.009 _ and 0.

256 _ with root mean square deviations of 0.64 _ and 0.801 _ respectively, therefore the AVHRR-based MCSSTs and read more NLSSTs had high accuracy in the seas around Taiwan.
