卫星遥感探测大气CO 2 浓度研究最新进展
摘要
Atmospheric carbon dioxide is an important and long-lived greenhouse gas.Satellite measurements of the distribution of the global atmospheric CO2 would get its continuous change.Improved quantitative understanding of the distribution and variability of the sources and sinks of CO2 and the global carbon cycle would be done,furthermore,the research and prediction on the global climate change would be enhanced.The remote sensing of the atmospheric CO2 from instrumentation aboard satellite has been a new area of research.The research on the remote measurement of the distribution of the atmospheric CO2 from satellite is summarily commented.Firstly,the temporal and spatial distribution and variability of atmospheric CO2 concentration monitored by direct instrument observations is presented,then the main methods and results of satellite remote sensing measurements of atmospheric CO2 concentration are reviewed,including the measurements of the near infrared reflected sunlight or the thermal infrared emission spectroscopy and the combination of both measurement,finally the summary and prospects are discussed briefly.
