| 摘 要： | 选取同天过境的Landsat5TM和HJ-1B红外相机数据,在获取3个大气参数后,结合辐射传输模型分别对大亚湾核电基地附近海域海表温度和温排水温升区的分布情况进行遥感监测,对比结果显示,环境卫星遥感监测数据与TM数据监测所得温排水在空间分布上具有较高一致性,二者反演出的绝对温度相差不超过1.1℃,相同温升等级范围内的相对温度均值也不超过0.4℃.因此,HJ-1B红外相机可满足核电站热污染的监测需求.

| Abstract: | The infrared data of TM and HJ-1B sensor on the same day were selected to monitor the distribution of surface temperature and thermal discharge in Daya Bay plant by the radiation transfer model after getting the three atmospheric parameters. The comparative results showed that there was a high consistency between the two kinds of sensors. Specifically, the absolute temperature difference of the thermal discharge inversion was less than 1.1℃, and the difference between the two average relative temperatures in the same temperature rising level was no more than 0.4℃. Therefore, the infrared satellite data of HJ-1B could meet the demand of the thermal pollution monitoring. |
