A comparison is made of the calculation of the spatial distribution of Cherenkov radiation from the primary proton performed with allowance for aerosol attenuation, with experimental data measured under different weather conditions at the Yakutsk EAS installation. It is shown that the transparency of the atmosphere affects the shape of the radial distribution of Cherenkov photons. With visibility range V = 15 km, calculations are close to experimental measurements, and more than 25 km - are minimal. This circumstance is used in the Yakutsk array as one of the criteria for selecting showers for further analysis and obtaining the exact characteristics of an EAS.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
