基于逐行GENSPECT模型的Argus 1000空间数据二氧化碳反演
Carbon dioxide retrieval of Argus 1000 space data by using GENSPECT line-by-line radiative transfer model
摘要:
微型光谱仪Argus 1000在太空中持续监测痕量气体的来源和汇。通常认为,在其他气体中,$\text{CO}_\text{2}$是引起温室效应的主要因素。Argus 1000沿其轨道收集有价值的光谱数据,可以进行分析和检索。本文介绍了用GENSPECT逐行程序反演$1580$ ~ $1620$ nm近红外窗口内的$\text{CO}_\text{2}$气体。2010年5月31日在不列颠哥伦比亚省上空获取的Argus 1000空间数据表明,$\text{CO}_\text{2}$增强了约$30\%$。
英文摘要:
The micro-spectrometer Argus 1000 being in space continuously monitors the sources and sinks of the trace gases. It is commonly believed that among other gases $\text{CO}_\text{2}$ is the major contributor causing the greenhouse effect. Argus 1000 along its orbit gathers the valuable spectral data that can be analyzed and retrieved. In this paper we present the retrieval of $\text{CO}_\text{2}$ gas in the near infrared window $1580$ to $1620$ nm by using line-by-line code GENSPECT. The retrieved Argus 1000 space data taken over British Columbia on May 31, 2010 indicates an enhancement of $\text{CO}_\text{2}$ by about $30\%$.
