Abstract:
A new method for the estimation of the integral content of NO2 in the boundary layer of the atmosphere by a combination of spectral measurements, incoming from the zenith scattered solar radiation in the daytime and in the twilight period, is described briefly. Effects of the major factors, affecting the accuracy of the estimation, such as clouds and albedo of the underlying surface, analyzed. It is shown that in cloudless condition and with the cloud lower boundary located above the near-surface layer of NO2, the de-termination of the integral content in the surface layer is possible with an error of 15-25%.
