遥感技术在大气监测中的应用

Application of Remote-sensing Technology in Atmospheric Monitoring

采用航天遥感技术方法对广东珠江口区域进行宏观的面状调查 ,分析卫星遥感像元信息构成的物理机制 ,以实验证明 ,像元信息可概化为土壤、植被、水体等基本信息类型的线性集合与污染气体信息的简单叠加 .首次从TM卫星数据直接定量提取区域大气污染气体累加浓度信息 .结果表明 ,所提取的污染信息将对珠江口大气污染状况有较客观。

Remote-sensing technology is used to investigate the restrict of Shajiao Power Plant in Guangdong. Satellite physical mechanism of remote-sensing information is analyzed. Models of remote-sensing identification and management of emitted gas are established and the information of gas diffusion is taken out.It is the first time to get the cumulative concentration information from TM satellite data.The results show that the pollution information from remote-sensing image can objectively represent the atmospheric pollution situation caused by a thermal power plant.
