根据萨默菲尔德的吸收测量，确定了臭氧9.6 μ波段的向上和向下辐射通量以及大气的加热和冷却速率。三种不同的臭氧分布曲线以及三种不同的温度-高度曲线已被用于这些计算。与9.6 μ臭氧带相互作用的辐射总是起到冷却从地球表面到几公里高度的大气层和加热从那里到大约20公里的区域的作用。在这一地区，每天的加热或冷却速率从未超过零点几度。另一方面，从35到60公里，通常的冷却数量级为2到3°C/天，但如果上层的温度高于正常温度，冷却速度可能会大得多。如果没有其他因素的变化对热平衡产生影响，低海拔臭氧量的增加可能会导致地球表面温度升高几摄氏度，以恢复红外平衡。在这些计算中，已经考虑到了谱线的压力展宽和重叠，以及已知对该问题具有重要意义的所有其他物理现象。并对结果的准确性作了估计。
The upward and downward radiation flux and the heating and cooling rate in the atmosphere have been determined for the 9.6 μ band of ozone from the absorption measurements of Summerfield. Three different ozone distribution curves as well as three different temperature-height curves have been used for these calculations. The radiations that interact with the 9.6 μ ozone band always act to cool the atmosphere from the earth's surface to a height of several kilometres and to heat the region from there to approximately 20 km. The heating or cooling rate is never larger than a few tenths of a degree Celsius per day in this region. On the other hand, from 35 to 60 km the usual order of magnitude of the cooling is 2 to 3°C/day, but the cooling rate can be considerably larger if the upper layers have a higher temperature than normal. An increase in the ozone amount at the lower altitudes may cause the surface temperature of the earth to rise several degrees Celsius in order to restore infra-red equilibrium, if no other factors change that produce an effect upon the heat balance. The pressure broadening and overlapping of the spectral lines have been taken into account in these calculations together with all other physical phenomena that are known to be of importance to the problem. An estimate is given for the accuracy of the results.
