MODIS-Derived Snowmelt Timing Maps, Version 2

Map of snowmelt date.

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.

The second version of snowmelt timing maps for North America is available for the period 2001 through 2018.

Monthly Hydrological Fluxes for ABoVE Domain

Average annual precipitation.

Average annual precipitation for 1979-2010 at 0.25 degree resolution across the Arctic Boreal Vulnerability Experiment study domain.

Estimated historical water balance climatologies are available for the Arctic-Boreal Vulnerability Experiment (ABoVE) study domain.

Temporal Dynamics of Lake Area in the Arctic

Four ABoVE study sites.

Near-daily CubeSat imagery was collected within four large regions across the ABoVE study area. Timeseries of lake area were derived from the CubeSat imagery for more than 80,000 lakes in these regions.

Near-daily CubeSat imagery provides information on the seasonal dynamics of more than 80,000 lakes.
