Показано, что в рассеивающей атмосфере применение метода ДОАС может приводить к заметным погрешностям оценок концентраций метана. Предложено дополнять его процедурой фильтрации сигналов, искаженных эффектами атмосферного рассеяния, которая учитывает корреляцию погрешностей восстановления концентраций метана и водяного пара, обусловленных неопределенностью траектории фотонов, распространяющихся в рассеивающей атмосфере. Данная корреляция оценивалась путем численных расчетов указанных погрешностей для модельной атмосферы, включающей в себя перистые облака и два типа приземных аэрозолей.</p></abstract><trans-abstract xml:lang="en"><p>The article discusses the application of the method of differential optical absorption spectroscopy (DOAS) to the problems of localized methane emission from satellite spectral measurements. It is shown that the application of the DOAS method in a scattering atmosphere can lead to significant errors in the estimates of methane concentrations, and it is proposed to supplement it with a filtering procedure for signals distorted by the effects of atmospheric scattering. The procedure takes into account the correlation of errors in the retrieved concentrations of methane and water due to the uncertainty of the trajectory of photons propagating in the scattering atmosphere. This correlation has been estimated by numerical calculations of the indicated errors for a model atmosphere that includes cirrus clouds and two types of surface aerosols.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>спутниковое дистанционное зондирование</kwd><kwd>атмосферный метан</kwd><kwd>рассеяние света</kwd><kwd>перистые облака</kwd><kwd>аэрозоль</kwd></kwd-group><kwd-group xml:lang="en"><kwd>satellite remote sensing</kwd><kwd>atmospheric methane</kwd><kwd>light scattering</kwd><kwd>cirrus clouds</kwd><kwd>aerosol</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Белорусского республиканского фонда фундаментальных исследований (договор № Ф22КИ-035)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">H.
