NVsnow-charts

Charts compare current and historic data from SNOTEL basin groups or individual sites. Basin charts combine data from multiple SNOTEL sites within and adjacent to a watershed. Drop downs use ALL CAPS for main basins, while Title Case is used for sub-basins. Charts include statistical data based on the period of record data set. Statistics include: daily maximum, daily median, and daily minimum, median peak (SWE only) and background shading based on the 10th, 30th, 50th, 70th, and 90th percentiles. The user can select and compare year(s) and statistics by clicking titles on and off in the legend. Additional user information about interactive charts is available here.
