The approach to normalization of the vegetation index calculated from measurements of the spectroradiometer MODIS is discusses in the paper. To do this, the normalization involves additional spectral channels of a spectroradiometer, based on the calculated cloud and snow indices allowing one to build a cloud mask and to allocate time periods of the presence of clouds. The built model for vegetation index dependency on the temperature allows further improvement of the form of time series of the vegetation index. The results of the application of the proposed approach to the real measurements are discussed in the paper.
