Припяти. Рассмотрен период с апреля 2018 г. по март 2022 г. Трофический статус р. Припяти формируется под влиянием естественных факторов (алгоритмы группы А) и антропогенных воздействий (алгоритмы группы Б). Установлено, что во внутригодовой изменчивости концентрации хлорофилла а наблюдается снижение концентраций хлорофилла а за период с сентября/октября по декабрь/январь и их рост за период с февраля/марта по сентябрь/октябрь. Во внутригодовом разрезе трофический статус р. Припяти по алгоритмам группы А в основном изменяется от α-евтрофного до β-евтрофного, а для группы Б он политрофный. В многолетнем плане изменчивости среднемесячных величин трофический статус р. Припяти в основном по группе А евтрофный, а по группе Б находится в диапазоне от β-евтрофного до политрофного. Для окончательного вывода о степени эвтрофирования р. Припяти потребуется более продолжительный период наблюдений. Исследование пространственной изменчивости концентрации хлорофилла а по течению р. Припяти не выделило статистически значимых трендов, но в то же время установило влияние притоков.</p></abstract><trans-abstract xml:lang="en"><p>The article shows the possibility of using satellite information to assess the degree of eutrophication of the river. Pripyat. The period from April 2018 to March 2022 was considered. Pripyat is formed under the influence of natural factors (algorithms of group A) and anthropogenic influences (algorithms of group B). It has been established that in the intra-annual variability of chlorophyll-а concentration, there is a decrease in chlorophyll-а concentrations from September/October to December/January, and an increase in concentration from February/March to September/October. In the intra-annual section, the trophic status of the river. Pripyat according to the algorithms of group A mainly changes from α-eutrophic to β-eutrophic, and for group B it is polytrophic. In the long-term plan of variability of monthly averages, the trophic status of the river. Pripyat is mainly eutrophic in group A, and in group B it ranges from β-eutrophic to polytrophic. For the final conclusion about the degree of eutrophication of the river. Pripyat will need a longer observation period. Study of the spatial variability of the concentration of chlorophyll-а along the river. Pripyat did not identify statistically significant trends, but at the same time established the influence of inflows.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вода</kwd><kwd>река</kwd><kwd>Припять</kwd><kwd>спутник</kwd><kwd>хлорофилл а</kwd><kwd>эвтрофикация</kwd><kwd>трофический статус</kwd><kwd>трофность</kwd><kwd>Sentinel-2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>water</kwd><kwd>river</kwd><kwd>Pripyat</kwd><kwd>satellite</kwd><kwd>chlorophyll-а</kwd><kwd>eutrophication</kwd><kwd>trophic status</kwd><kwd>trophicity</kwd><kwd>Sentinel-2</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">Неверова-Дзиопак, Е.
