| Abstract: | Satellite Infrared remote sensing (RS) technologies, which include the near-infrared, shortwave infrared, middle infrared, and thermal infrared RS, have been widely used over the world, and it has been playing an important role in the field of environmental protection in China. This paper focuses on introducing the recent applications of RS, including: monitoring the straw burning, dust storm, aerosol optical depth, particle matters, and haze pollution for air environment quality monitoring; monitoring the blue algae, water quality (factors include chlorophyll-a, suspended sediment, transparency, and nutrition condition index), water surface temperature, thermal-water pollution, and warm water discharge of nuclear power plant for water environment quality monitoring; and monitoring the soil water content, vegetation water content, drought, evapotranspiration, land surface temperature, and urban heat island for ecological environment quality monitoring. Some typical application cases are illustrated in this paper, including the distribution of straw burning sites in China using satellite data; the monitoring of warm water discharge for Dayawan nuclear power plant; and the monitoring of Beijing urban heat island. In the end, we point out the existing limitations for remote sensing application, such as the low application level of domestic satellites due to its low spatial and temporal resolution, the limited signal to noise ratio, the deficiency in radiation calibration, the lack of original created algorithms, and the deficiency in ground observation and validation. Meanwhile, we proposed suggestions for further development, such as vigorously developing domestic infrared remote sensors, enhancing the level of satellite and ground radiation calibration, studying the original algorithms for environment monitoring, and constructing comprehensive ground experiment bases, etc. The development of satellite RS techniques, especially for the Project of China High Resolution Earth Observation, which is designed to carry various advanced infrared RS payloads, will significantly improve the quantitative monitoring level of environmental application in China. |
