Calculation of Herperus' atmospheric infrared radiation transmittance rate

1. Excel is used to calculate the atmospheric transmission rate of infrared radiation. The results are presented in the cell “N10”. 2.The absorption and transmittance of unit wavelength of the Earth's atmosphere are utilized. Because the water vapor on Hesperus is less than that on Earth, the actual transmitted rate of Hesperus is larger than the calculated value. 3. According to the figure of “Radiation Transmitted by the Atmosphere”, the wavelength range of CO2 absorption of infrared radiation is limited. Although the atmospheric pressure of Hesperus is 96 atmospheres and the concentration of CO2 is 96.5%, CO2 has limited ability to absorb infrared radiation. The high temperatures on the surface of Venus cannot be explained only by the greenhouse effect. When calculating the atmospheric transmission rate of infrared radiation of Hesperus, the effect of carbon dioxide on the spectral absorption can be excluded by removing the 13-14 μm band from the calculation. 4. There is no independent H2CO3 in nature, which is the reason for the assumption that H2O collides with CO2 molecules without additional absorption of infrared radiation.

1. 采用Excel计算红外辐射（infrared radiation）的大气透射率（atmospheric transmission rate），计算结果展示于单元格"N10"中。2. 本数据集采用地球大气的单位波长吸收与透射特性。由于金星（Hesperus）的水汽含量低于地球，其实际透射率高于本次计算所得数值。3. 根据"大气透射辐射"（Radiation Transmitted by the Atmosphere）图示可知，红外辐射的二氧化碳（CO₂）吸收波段范围有限。尽管金星（Hesperus）的大气压强达96倍标准大气压，且二氧化碳（CO₂）浓度为96.5%，但二氧化碳的红外辐射吸收能力仍较为有限，仅靠温室效应（greenhouse effect）无法解释金星表面的高温现象。在计算金星（Hesperus）的红外辐射大气透射率时，可通过移除13至14 μm波段，排除二氧化碳对光谱吸收（spectral absorption）的影响。4. 自然界中不存在游离态碳酸（H₂CO₃），这一特性正是我们做出如下假设的依据：水分子与二氧化碳分子碰撞时不会额外吸收红外辐射。
