Is the snow melting earlier?

Mean snowmelt timing map

Mean snowmelt Day of Year (DOY) for the years 2001-2015 for North America. The DOY values for snowmelt timing were identified by observing the transition from snow-cover to no-snow for individual MODIS pixels throughout the annual melt period.

A new time-series analysis of snow cover has identified the day of snowmelt in each MODIS pixel across North America in each year from 2001 - 2015.
