Вместе с тем, если поверхность гомогенна, возможно потребуется дополнительный признак гомогенности для подтверждения факта равенства оценок пикселей.</p><p>В статье рассмотрена возможность формирования новой экстремальной спектральной сигнатуры, характеризующей степень температурной гомогенности поверхности земляной поверхности на базе измерения поверхностной температуры спутниковыми средствами. Температурно-гомогенным участком принято называть те участки, в которых яркостная температура на верхней границе (TC) атмосферы не зависит от излучательности. Вместе с тем, равенство ТС(Е) = С; С = const возможно в двух случаях: (а) если Е изменяется от Еmin до Еmax, однако, TC при этом не изменяется; (б) если E неизменяется и равно постоянной величине то TC также не изменяется. Предложен метод оценки температурной однородности исследуемой поверхности земли. Сформирован новый показатель температурной однородности исследуемых участков земной поверхности. С применением метода вариационной оптимизации показано, что если яркостная температура на верхней границе атмосферы постоянна в принятых пределах излучательности исследуемого участка, то предлагаемый показатель гомогенности достигает максимума при некотором принятом ограничительном условии. При условии соблюдения этого ограничения факт максимума принятого показателя может быть использован в качестве признака температурной однородности участка.</p></abstract><trans-abstract xml:lang="en"><p>Spatial resolution is usually understood as the ability to distinguish nearby pixels on a surface. At the same time, if the surface is homogeneous, an additional sign of homogeneity may be required to confirm the fact of equality of pixel estimates. The article considers the possibility of forming a new extreme spectral signature characterizing the degree of temperature homogeneity of the surface of the Earth’s surface based on the measurement of surface temperature by satellite means. A temperature-homogeneous area is usually called those areas in which the brightness temperature at the upper boundary of the atmosphere does not depend on the emissivity, i.e. the TC(E) function is equal to a constant value. However, the equality TC(E)=C; C=const is possible in two cases: (a) if E changes from E_min to E_max, however, TC does not change;(b) if E is unchanged and is equal to a constant value, then TC also does not change. A method for estimating the temperature homogeneity of the studied surface of the earth is proposed. A new indicator of the temperature uniformity of the studied areas of the Earth’s surface has been formed. Using the variational optimization method, it is shown that if the brightness temperature at the upper boundary of the atmosphere is constant within the radiance of the studied area then the proposed new indicator reaches a maximum with the some accepted restriction. The fact of maximum of newly accepted indicator can be used as a sign of the temperature uniformity of the site.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>температурная однородность</kwd><kwd>тепловые потоки</kwd><kwd>подстилающая поверхность</kwd><kwd>верхняя граница атмосферы</kwd><kwd>дистанционное зондирование Земли</kwd><kwd>инфракрасный сенсор</kwd><kwd>Landsat</kwd><kwd>спектральная радиация</kwd><kwd>спектральная сигнатура</kwd><kwd>спектрорадиометр</kwd><kwd>эвапотранспирация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>temperature uniformity</kwd><kwd>heat fluxes</kwd><kwd>underlying surface</kwd><kwd>upper boundary of the atmosphere</kwd><kwd>Earth remote sensing</kwd><kwd>infrared sensor</kwd><kwd>Landsat</kwd><kwd>spectral radiation</kwd><kwd>spectral signature</kwd><kwd>spectroradiometer</kwd><kwd>evapotranspiration</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Li Z.L., Tang B.H., Wu H., Ren H., Yan G., Wan Z., Trigo I.F., Sobrino J.A.
