Abstract. The article describes modified spectral method for measuring CO2 con­centration to determine the activity of photosynthesis processes in the vegetative landscape, in view of water vapors, as well as atmospheric aerosol effect on the width of the carbon dioxide absorption line at a wavelength of 2.7 μm. The relevance of the work is described by necessity for prompt determination of the activity of photosynthesis processes in vege­tation fields of the landscape by conducting remote spectral measurements.

Keywords: vegetation landscape, measurements, carbon dioxide, photosynthetic activity, indirect measurements, random error.
