Abstract

This article is based on the thermal infrared data obtained from Environmental mitigation B satellite (HJ-1B) and Storm III satellite (FY-3), using generalized single-channel method, retrieved the surface temperature of costal sea around the Tianwan Nuclear Power Plant in winter and summer to get the quantitative information about the diffusion and gradient of the thermal discharge from the nuclear power station. Then the retrieval results were compared with the MODIS sea surface temperature (SST) products. It indicated that the thermal infrared data from HJ-1B and FY-3 were able to research on the distribution of thermal discharge. Furthermore, based on inversion of the SST distribution map, spatial and temporal distribution variations of thermal discharge were analyzed simply. The distribution is significantly different among the different seasons. During the winter months, the thermal discharge extended to a sector area around the power station, while in summer it limited to a rater longer and narrower area in one side of the bay. And the area where the SST has increased more than 3 °C in winter was much larger than that in summer.
