The influence of atmosphere is mostly detected in far red region (750-860 nm). As a result of the research was shown that significant influence of the optical state of atmosphere appears outside the spectral range for derivative vegetation index calculation. Therefore, it is suitable for remote chlorophyll content estimation of crops under any weather conditions. Influence of other weather phenomena that can alter the spatial orientation of leaves, causes vegetation index variations within 4%. Reflectance spectrum range of 750-860 nm can be cleaned from weather distortions with digital filter picked up by us. Later this spectrum range can be applied for estimation of soil vegetation projective surface. Product Description popup.authors Бондаренко О.Ю. Петрушевська В.Н. Туменок Л.В.
