The Yenisei River originates from the Sayan Mountains in Mongolia and is the largest river that transports water to the Arctic Ocean. Quantifying the distribution of river ice in the Yenisei River and studying its spatiotemporal changes are crucial for understanding the response of large rivers in the high latitude areas of the Northern Hemisphere to climate change. In this study, the MODIS daily snow cover data products (MOD10A1/MYD10A1) from 2002 to 2021 were used to carry out cloud removal processing to extract daily river ice extent with a resolution of 500m.
