A Universal Ratio Snow Index for Fractional Snow Cover Estimation
IEEE Geoscience and Remote Sensing Letters, 2021The moderate resolution imaging spectroradiometer (MODIS) snow algorithm has been used to generate global fractional snow cover (FSC) at a pixel size of 500 m using a linear regression relationship (called “FRA6T”) between FSC and the normalized difference snow index (NDSI).

Estimate of fractional snow cover using MODIS data
IEEE International Geoscience and Remote Sensing Symposium, 2003Information from the Moderate Resolution Imaging Spectroradiometer (MODIS), launched on the Terra satellite in December 1999, is considered a powerful means to improve global snow cover maps and to generate a fractional snow cover product. Estimates of snow fraction are viewed as useful for atmospheric and hydrologic snowmelt runoff modeling ...

A Multisource Statistical Method to Downscale Snow Cover Fraction in Mountain Regions
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021The monitoring of the snow cover area (SCA) from optical sensors on board of satellites is affected by the trade-off between spatial and temporal resolution provided by the current operational missions. This limits the possibility to exploit satellite SCA for hydrological purposes.

Estimating fractional snow cover from MODIS using the normalized difference snow index
Remote Sensing of Environment, 2004Abstract Snow-cover information is important for a wide variety of scientific studies, water supply and management applications. The NASA Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS) provides improved capabilities to observe snow cover from space and has been successfully using a normalized difference snow index (

SNOW COVER EFFECT ON THE ERODIBLE SOIL FRACTION
Canadian Journal of Soil Science, 1969The effect of snow cover on the overwinter breakdown of medium-textured soils in southwestern Saskatchewan was studied during the winter of 1967–1968. Where a continuous snow cover was provided artificially (with snow fencing), there was a decline in the percentage of soil particles < 1 mm in diameter from October to April, with a marked drop from ...

Estimating Fractional Snow Cover in Mountain Environments with Fuzzy Classification
International Journal of Applied Geospatial Research, 2012The disproportionate amount of water runoff from mountains to surrounding arid and semiarid lands has generated much research in snow water equivalent (SWE) modeling. A primary input in SWE models is snow covered area (SCA) which is generally obtained via satellite imagery.

Estimation of Fractional Snow Cover From Fy-4a/Agri
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019China’s new generation of geostationary weather satellite, FengYun-4A (FY-4A) carrying the Advanced Geosynchronous Radiation Imager (AGRI) was launched on December 1 2016 and its data became publicly available on March 12 2018. The availability of high temporal observation at visible, near infrared, short-wave infrared and long-wave infrared bands over

IEEE Geoscience and Remote Sensing Letters, 2012
The normalized difference snow index (NDSI), a key part of the snow-mapping algorithm for extracting snow information from remotely sensed imageries, has been frequently employed in acquiring snow cover extent in the past decades. A linear regression analysis has been frequently used in estimating snow cover fraction (SCF) on a subpixel basis by ...

A new snow cover fraction parametrization for the ECHAM4 GCM
Climate Dynamics, 2001Snow cover fraction (SCF) has a significant influence on the surface albedo and thus on the radiation balance and surface climate. Long-term three dimensional simulations with general circulation models (GCMs) show that the SCF greatly affects the climate in the Northern Hemisphere. By means of both ground observations and remotely sensed data, several
