Greenhouse gases absorb the Earth's thermal radiation and partially return it to the Earth's surface. When accumulated in the atmosphere, greenhouse gases lead to an increase in the average global air temperature and, as a result, climate change. In this paper, an approach to measuring CO2 and CH4 concentrations using Fourier transform infrared spectroscopy (FTIR) is proposed. An FTIR spectrometer mockup, operating in the wavelength range from 1.0 to 1.7 μm with a spectral resolution of 10 cm-1, is described. The results of CO2 and CH4 observations throughout a day in urban conditions are presented. A low-resolution FTIR spectrometer for the 16U CubeSat spacecraft is described. The FTIR spectrometer has a 2.0-2.4 μm spectral range for CO2 and CH4 bands, a 0.75-0.80 μm range for reference O2 bands, an input field of view of 10-2 rad and a spectral resolution of 2 cm-1. The capabilities of the 16U CubeSat spacecraft for remote sensing of greenhouse gas emissions using a developed FTIR spectrometer are discussed. The design of a 16U CubeSat spacecraft equipped with a compact, low-resolution FTIR spectrometer is presented.
温室气体吸收地球的热辐射，并将部分辐射返回地球表面。当温室气体在大气中积累时，会导致全球平均气温上升，进而引发气候变化。本文提出了一种利用傅里叶变换红外光谱法（FTIR）测量二氧化碳和甲烷浓度的方法。描述了一种工作在1.0至1.7μm波长范围内、光谱分辨率为10 cm-1的傅里叶变换红外光谱仪模型。给出了在城市环境中全天对二氧化碳和甲烷的观测结果。描述了一种用于16U立方星航天器的低分辨率傅里叶变换红外光谱仪。该傅里叶变换红外光谱仪对二氧化碳和甲烷波段的光谱范围为2.0至2.4μm，对参考氧气波段的光谱范围为0.75至0.80μm，输入视场为10-2弧度，光谱分辨率为2 cm-1。讨论了16U立方星航天器利用所研制的傅里叶变换红外光谱仪进行温室气体排放遥感的能力。介绍了配备紧凑、低分辨率傅里叶变换红外光谱仪的16U立方星航天器的设计。
