Abstract. A new methodology for validating the results of satellite measurements of soil salinity using satellite estimates of the SAVI and VSSI indices has been developed. A linear weighted sum of exponential functions of these indices has been proposed as a new soil salinity index. It has been shown that the proposed new index has an extremum in the form of a minimum of the signal in the red range. The presence of such a minimum eliminates the need to search for soil with a sufficiently high conductivity on the test site when validating the obtained large estimates of the SAVI and VSSI indices.
