Estimating fractional snow cover from MODIS using the normalized difference snow index
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 (NDSI), along with threshold tests, to provide global,...

متن کاملA regional snow-line method for estimating snow cover from MODIS during cloud cover
The objective of this study is to propose and evaluate a method for snow cover mapping during clouds using the daily MODIS/Terra snow cover product. The proposed SNOWL approach is based on reclassifying pixels assigned as clouds to snow or land according to their relative position to the regional snow-line elevation. The accuracy of the SNOWL approach is evaluated over Austria, using daily snow...
متن کاملEuropean Snow Cover Characteristics between 2000 and 2011 Derived from Improved MODIS Daily Snow Cover Products
Mean snow cover duration was derived for the entire continent of Europe based on the MODIS daily snow cover products MOD10A1 and MYD10A1 for the period from 2000 to 2011. Dates of snow cover start and snow cover melt were also estimated. Polar darkness north of ~62°N and extensive cloud coverage affected the daily snow cover, preventing a direct derivation of the desired parameters. Combining s...
متن کاملSnow Cover
Snow cover is a layer of snow on the earth’s surface, which is mainly results from snowfalls. The snow cover can be temporary, when a snow melts during several hours or days after its formation, and it can be stable, when it remains for the whole winter or with short interruptions. The snow cover formation on the globe is determined (conditioned) by the geographical zonality, surface relief, an...
