Precipitation trends over the Russian permafrost‐free zone: removing the artifacts of pre‐processing
Abstract Rain gauge changes, changes in the number of observations per day, and inconsistent corrections to observed precipitation data during the 20th century of the meteorological network of the former Soviet Union make it difficult to address the issue of century time‐scale precipitation changes....
