Abstract

The feasibility of developing a technique for retrieving the relative content ¹³CO₂/¹²CO₂ in the atmosphere as a result of solving the inverse problem of satellite sounding of the atmosphere with IASI spectrometers in the thermal infrared region has been studied. Synthetic spectra with resolution and noise level characteristic of an improved version of the IASI-NG spectrometer were used in a model experiment. It is shown in computational experiments that the vertical profiles of the ¹³CO₂ concentration and the relative ¹³CO₂/¹²CO₂ content in the atmosphere are quite satisfactorily retrieved in the troposphere for the altitude range 2–11 km, which seems promising for future use of the technique suggested.

摘要

开发用于检索所述相对含量的技术的可行性¹³ CO ₂ / ¹² CO ₂在大气中的，作为解决卫星探测与在热红外区域IASI光谱仪的气氛的逆问题的结果进行了研究。在模型实验中使用了具有改进型IASI-NG光谱仪的具有分辨率和噪声级特征的合成光谱。它是在计算实验表明的垂直剖面¹³ CO ₂浓度和相对¹³ CO ₂ / ¹² CO ₂ 在2-11 km的高度范围内，对流层中的大气中含量得到了令人满意的恢复，这对于将来使用所建议的技术似乎是有希望的。
