Visualizing gridded time series data with self organizing maps: An application to multi-year snow dynamics in the Northern Hemisphere

► Demonstrated the use of SOMs to visually analyze long-term and interannual patterns in gridded SWE over the Northern Hemisphere. ► Identified dominant modes of SWE patterns and their interannual transitions in select locations. ► Identified relationships between the inter annual transitions as identified by the SOM with synoptic climatic indices.
