摘　　要：根据2013-11-15过境的Landsat8 TIRS和HJ-1B IRS热红外遥感数据,分别采用辐射传输方程法和单窗算法对田湾核电基地附近海域温度分布情况进行遥感监测,利用海面实测的数据验证监测结果的可靠性,并分析了监测结果的一致性。结果表明,Landsat8 TIRS和HJ-1B IRS的海面温度监测结果是可靠的,海面温度范围在数值和空间分布上具有较高一致性。因此,将Landsat8与HJ-1B相互补充,在海温监测方面具有较大的应用前景。Based on the thermal infrared remote sensing data of Landsat8 TIRS and HJ-1 B IRS, the universal single window algorithm and the radiation transfer equation method were taken to implement temperature retrieving to monitor the distribution of surface temperature and thermal discharge in the sea region near Tianwan nuclear plant, Lianyungang City, Jiangsu Province in Nov. 15, 2013.The consistency of both sensors was analyzed and the reliability of the retrieving algorithms were tested with synchronal-measured temperature. The results show that there is a high consistency between the two kinds of sensors and the algorithm for each sensor is reliable. Landsat8 and HJ-1 B have great potential application for sea temperature monitoring, due to the mutual complementation of the two sensors.
