  • Are vegetation influences on Arctic–boreal snow melt rates detectable across the Northern Hemisphere

    Open AccessHeather Kropp, M M Loranty et al.ARTICLEEnvironmental Research Letters2022

    The timing and rate of northern high latitude spring snowmelt plays a critical role in surface albedo, hydrology, and soil carbon cycling. Ongoing changes in the abundance and distribution of trees and shrubs in tundra and boreal ecosystems can alter snowmelt via canopy impacts on surface energy partitioning. It is unclear whether vegetation-related processes observed at the ecosystem scale influence snowmelt patterns at regional or continental s…

  • Polar amplification and elevation-dependence in trends of Northern Hemisphere snow cover extent, 1971–2014

    Open AccessMarco A Hernández‐Henríquez, Marco A Hernández-Henríquez et al.ARTICLEEnvironmental Research Letters2015

    Recent years (i.e., 2007–2014) have exhibited large declines in snow cover extent (SCE) in the Northern Hemisphere (NH), marked by earlier snowmelt in the springtime. In Northern latitudes, the snow-albedo feedback (SAF) is most pronounced in the spring and may be contributing to these decreasing trends in SCE. Rising surface air temperatures and changes in precipitation patterns could also vary the declining trends in SCE depending on latitude a…

  • New satellite climate data records indicate strong coupling between recent frozen season changes and snow cover over high northern latitudes

    Open AccessYoungwook Kim, John S Kimball et al.ARTICLEEnvironmental Research Letters2015

    We examined new satellite climate data records documenting frozen (FR) season and snow cover extent (SCE) changes from 1979 to 2011 over all northern vegetated land areas (≥45 °N). New insight on the spatial and temporal characteristics of seasonal FR ground and snowpack melt changes were revealed by integrating the independent FR and SCE data records. Similar decreasing trends in annual FR and SCE durations coincided with widespread warming (0.4…

  • Is Eurasian October snow cover extent increasing

    Open AccessRoss Brown, CHRIS DERKSENARTICLEEnvironmental Research Letters2013

    A number of recent studies present evidence of an increasing trend in Eurasian snow cover extent (SCE) in the October snow onset period based on analysis of the National Oceanic and Atmospheric Administration (NOAA) historical satellite record. These increases are inconsistent with fall season surface temperature warming trends across the region. Using four independent snow cover data sources (surface observations, two reanalyses, satellite passi…

  • Spatial‐temporal patterns of snow cover in western Canada

    Open AccessCarson J Q Farmer, Carson Farmer et al.ARTICLECanadian Geographies /…2009References: 38

    Snow cover is often measured as snow‐water equivalent (SWE), which refers to the amount of water stored in a snow pack that would be available upon melting. Snow cover and SWE represent a source of local snow‐melt release, and are sensitive to regional and global atmospheric circulation, and changes in climate. Monitoring SWE using satellite‐based passive microwave radiometry has provided nearly three decades of continuous data for North America …
