   <abstract xml:lang="ru">
    <p>В работе рассматривается вопрос о том, насколько сведения об облачном покрове, полученные при помощи спутниковых и модельно-интерполяционных методов, пригодны для мониторинга прозрачности атмосферы и определения условий наблюдения свечения верхней атмосферы Земли в конкретной наземной обсерватории. Для этой цели было проведено сравнение временной динамики локального облачного покрова по данным проекта ECMWF ERA5 и спутников NOAA, с прозрачностью ночной атмосферы, полученной при помощи цифровой фотокамеры. Динамика исследуемых характеристик рассматривалась в течение декабря 2020 г. для Геофизической обсерватории Института солнечно-земной физики, расположенной на Байкальской природной территории вблизи с. Торы (Бурятия, РФ). Результаты сравнительного анализа показали в целом хорошее согласие данных архива ECMWF ERA5 и облачности, наблюдаемой при помощи камеры. Недостатками являются отсутствие в архиве информации о быстрых вариациях облачности, а также положительные и отрицательные задержки в динамике облачных полей длительностью около двух часов. Вследствие нерегулярности и большой дискретности спутниковых данных и сложности определения облачности в темное время суток, уверенных выводов о применимости спутниковых данных сделать не удалось.</p>

    <p>The paper addresses the issue of how much cloud cover data obtained using satellite and model-interpolation techniques are suitable for monitoring the transparency of the atmosphere and determining conditions for airglow observations at a local geophysical observatory. For this purpose, we compared the temporal dynamics of cloud cover from ECMWF’s ERA5 reanalysis and NOAA satellites with the night atmosphere transparency according to a digital camera. We considered the dynamics of the addressed parameters at the Geophysical Observatory of the Institute of Solar-Terrestrial Physics, located in the Baikal Natural Territory near the village of Tory (Republic of Buryatia, Russia), during December 2020. The comparative analysis showed a generally good agreement between cloud cover data from ECMWF’s ERA5 climate reanalysis and those observed with the camera. Disadvantages are the lack of information on rapid variations in cloud cover in the reanalysis and positive and negative delays in the dynamics of cloud fields that last about two hours. Due to irregular satellite data, large time gaps between passes and difficulties in estimating cloud cover at night, we could not come to reliable conclusions concerning the applicability of satellite data.</p>
