Abstract

A method for estimating the radius of effect of a cloud field on the error of retrieving the reflection coefficient of cloudless areas of the earth's surface through gaps in the cloud field is considered. Within the framework of the proposed method, an interpolation equation is used to estimate the radius of this effect for various optical and geometric conditions of remote sensing. MODIS data are considered for an area with a radius of 50 km centered at a point with coordinates 53.2849º N, 103.4066º E in the period of July 1-31, 2021. The radius, within which the retrieved reflection coefficient of cloudless areas changes by 0.005 or more, is calculated from these data with the developed interpolation equation. The analysis shows that this radius ranges from 0.5 to 10 km and is highly correlated with the average cloud depth for the considered situations.
