Snow persistence (SP) or the snow cover index (SCI), is the fraction of time that snow is present on the ground for a defined period. SP was calculated on a pixel by pixel basis using MODIS/Terra Snow Cover 8-Day L3 Global 500m Grid, Collection 6 obtained from the National Snow and Ice Data Center (NSIDC). We computed the 1 January – 3 July SP for each year as the fraction of 8-day MODIS images with snow present. For more information on MODIS snow persistence please see: -Hammond, J. C., Saavedra, F.
