Cloud-free and canopy-adjusted snow cover fraction and snow cover days (where snow cover fraction > 0.15) data updated daily, with a typical two-day lag. Snow water equivalent data updated daily. In the snow cover percent and snow cover days time series, the black solid line represents the current near-real-time conditions and the gray shaded region is the interquartile range (includes half the years) of the MODIS record. The dashed line in the middle of the gray area shows the median of the historical data and the dotted lines at the top and bottom depict the years with the highest and lowest snow cover area. Snow water equivalent data are normalized to the median value for the day displayed, and only stations with at least 25 years of record are shown.
