Creation of a long-term high-resolution hydrometeorological archive for the Russian Arctic: methodology and first results
Abstract Taking into account that dangerous phenomena on the Arctic coast are increasing in number, providing the region with detailed hydrometeorological and climatic information with a horizontal resolution of at least several kilometers becomes particularly important. In this work, we obtain for...
