论文摘要
对流层顶是对流层和平流层之间的边界，因此其高度决定了大气中过程的性质，并取决于它们。确定对流层顶的高度的标准是垂直温度梯度在5 km以上和至少2 km厚的层中的降低。因此，确定对流层和平流层之间截面的高度的不确定性为2公里或更多。另外，由于许多原因的影响，温度曲线会发生变化，因此有时甚至无法确定对流层顶的高度。对流层和平流层中空气的光学特性不同，这使得使用带有光学传感器的辐射器以高精度测量截面的高度。带有光学传感器的辐射仪的发射使通过更改可见光的衰减系数来测量对流层的高度。事实证明，对流层顶的下边缘对应于衰减系数的急剧变化。结果的重复性通过辐射的同时发射得到了证实。工作结果将对天气预报和气候研究的任务有用。
The tropopause is the boundary between the troposphere and the stratosphere, so its height determines the nature of processes in the atmosphere and depends on them. The criterion for determining the height of the tropopause is a decrease in the vertical temperature gradient in a layer above 5 km and at least 2 km thick. Consequently, the uncertainty in determining the height of the section between the troposphere and the stratosphere is 2 km or more. In addition, the temperature profile changes due to the influence of many reasons, so sometimes the height of the tropopause cannot even be determined. The optical properties of air in the troposphere and stratosphere differ, which makes it possible to measure the height of the section with high accuracy using a radiosonde with an optical sensor. The launches of radiosondes with optical sensors made it possible to measure the height of the tropopause by changing the attenuation coefficient of visible light. It turned out that the lower edge of the tropopause corresponds to a sharp change in the attenuation coefficient. The repeatability of the results was confirmed by the simultaneous launch of radiosondes. The results of the work will be useful for the tasks of weather forecasting and climate research.
