Problems solved by technology

The outdoor experimental device for studying the absorption spectrum of atmospheric molecules is easily affected by external environmental factors, which makes the experimental data have great uncertainty; in the laboratory, a single absorption cell is often used to study the absorption spectrum parameters of atmospheric molecules, and the temperature of the sample cell , pressure, and gas concentration can only be at specific values, and cannot simulate the gradient distribution of parameters in each layer of the vertical atmosphere

When studying the spectral parameters of the entire layer of the atmosphere, the inversion can only be performed by combining the results of multiple experiments, which is time-consuming and laborious, and will inevitably cause system test errors
