В силу особенностей строения магнитного поля Земли ее приполярные области наиболее восприимчивы к вариациям потока космических лучей и другим проявлениям космической погоды. Расположенные в таких районах возвышенности особенно перспективны с точки зрения изучения этих явлений. В настоящее время в мире действуют две наземные обсерватории, отличающиеся повышенной чувствительностью к проявлениям солнечной активности, и обе они находятся в Антарктиде. В Российской Арктике имеется несколько горных районов, геофизические условия в которых схожи с таковыми на Антарктическом ледяном щите. Работа посвящена расчету физических величин, определяющих условия мониторинга космической погоды в этих районах, и рассмотрению вопроса о целесообразности строительства новых научных станций в этих местах. Показано, что установка новых станций приведет к повышению чувствительности сети обсерваторий к проявлениям солнечной и геомагнитной активности, в частности к росту числа регистрируемых солнечных протонных событий.

Due to the structural features of the geomagnetic field, Earth’s subpolar regions are the most affected by cosmic ray variations and other space weather phenomena. High grounds located in these regions are especially promising in terms of space weather research. Nowadays, there are only two high-altitude subpolar space weather observatories highly sensitive to solar activity, both located in Antarctica. In the Russian Arctic, we have several mountainous regions with geophysical conditions similar to that of the Antarctic ice sheet. In this paper, we calculate physical quantities that determine conditions for space weather observation in these regions and explore the expediency of building new scientific stations there. We show that establishment of the stations would enhance sensitivity of space weather observatory network and increase the number of detectable solar proton events.
