  • Spring snow melt timing and changes over Arctic lands

    James L Foster, David A Robinson et al.ARTICLEPolar Geography2008

    Spring snow cover over Arctic lands has, on average, melted approximately 4–7 days earlier since the late 1980s compared to the previous 20 years. The earlier disappearance of snow has been identified in non-mountainous regions at the 60° and 70°N parallels over Eurasia and North America using visible satellite observations of continental snow cover extent (SCE) mapped by the National Oceanic and Atmospheric Administration (NOAA). The change was …

  • Seasonal snow extent and snow mass in South America using SSMI passive microwave data 1

    James L Foster, A T C Chang et al.ARTICLEPolar Geography2001

    Seasonal snow cover in primarily non‐mountainous areas of South America was examined in this study using passive microwave satellite data from the Special Sensor Microwave Imagers (SSM/I) on board Defense Meteorological Satellite Program (DMSP) satellites. For the period 1992–1998, both snow‐cover extent and snow depth (snow mass) were investigated during the winter months (May‐August) in Argentina and Chile. Most of the seasonal snow in South Am…

  • Snow-mass intercomparisons in the boreal forests from general circulation models and remotely sensed data sets

    Open AccessJames Foster, James L Foster et al.ARTICLEPolar Record1996References: 12

    In much of the boreal forests, snow covers the ground for half of the year. Since these boreal forests comprise approximately 15% of the land normally covered by snow during the winter and upwards of 40% of the land surface normally snow-covered during the spring and autumn, reliable measures of snow cover and snow mass are required for improved energy-balance and water-balance estimates. In this study, results from snow-depth climatological data…

  • Determination of actual snow-covered area using Landsat TM and digital elevation model data in Glacier National Park, Montana

    Open AccessDorothy K Hall, James L Foster et al.ARTICLEPolar Record1995Cited by: 1References: 7

    In the future, data from the moderate resolution imaging spectroradiometer (MODIS) will be employed to map snow in an automated environment at a resolution of 250 m to 1 km. Using Landsat thematic mapper (TM) data, an algorithm, SNOMAP, has been developed to map snow-covered area. This algorithm will be used, with appropriate modification, with MODIS data following the launch of the first Earth Observing System (EOS) platform in 1998. SNOMAP has …

  • Derivation of Snow Water Equivalent in Boreal Forests Using Microwave Radiometry

    Open AccessJames L Foster, A T C Chang et al.ARTICLEARCTIC1991

    Efforts have been made by several investigators to produce a reliable global microwave snow algorithm to estimate snow depth or snow water equivalent (snow volume) and snow extent. Complications arise when trying to apply a global algorithm to specific regions where the climate, snowpack structure and vegetation vary. In forest regions, the microwave emission from dense coniferous forests may overwhelm the emission from the underlying snow-covere…
