Mean snowmelt Day of Year (DOY) for the years 2001-2018 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.

Snowmelt Timing Maps Derived from MODIS for North America, Version 2, 2001-2018

This dataset provides a new version of snowmelt timing maps (STMs), cloud interference maps, and a map of calculated snowmelt timing values for North America. The STMs are based on the Moderate Resolution Imaging Spectroradiometer (MODIS) standard 8-day composite snow-cover product MOD10A2 collection 6 for the period 2001-01-01 to 2018-12-31. The STMs were created by conducting a time-series analysis of the MOD10A2 snow maps to identify the DOY of snowmelt on a per-pixel basis. These data may be of interest to researchers investigating questions of phenology, hydrology, climatology, land management, recreation, and other areas.
