World Wide Daily Snow and Ice Cover Map. N. Hemisphere Snow Coverage Maps. The cryosphere which are areas covered by ice, snow, glaciers, or permafrost is an extremely dynamic part of our global system. Changes in seasons & climate bring great changes to the Earth's cryosphere. Infrared (IR) and microwave data from multiple satellites including. Snow Cover. Snow and ice influence climate by reflecting sunlight back into space. When it melts, snow is a source of water for drinking and vegetation; too much snowmelt can lead to floods. These maps show average snow cover by month. Mar 2000 — Jun 2020. Snow and Ice
July 28, 2020. Yesterday's snow cover extent across Northern Hemisphere lands. For more daily charts, including the departure from satellite-era normal, click the map.. Snow Extent CDR Update. Rutgers University Global Snow Lab maps, figures and tabular data are currently in the process of being updated to Northern Hemisphere SCE CDR v01r01.
Snow cover world. Daily updated map on Snow Cover Extent in Europe. Water (ice free) Land (snow free) Ice cover Snow cover . Read usefull information about the map. Full resolution (4 km/pixel) Map is based on the IMS snow analysis, as published by NOAA . Eurasia weekly snow cover since January 1972 according to Rutgers University Global Snow Laboratory. The thin blue line is the weekly data, and the thick blue line is the running 53 week average (approximately 1 year). The horizontal red line is the 1972-2019 average. Last week shown: week 27 in 2020. Snow cover is an important part of Earth's environment. Because it reflects most of the sunlight that hits it, snow helps to cool Earth's surface. Many areas of the world rely on snowmelt for drinking water and water for their crops. So scientists monitor where and how much of Earth's landscape is covered by snow.
The U.S. and Northern Hemisphere snow cover maps that are provided by the U.S. National Ice Center will no longer be served through this website or any NCEI website. The maps are still provided via the U.S. National Ice Center’s website and are available here: https:. Snow Cover Extent Snow Water Equivalent; Northern Hemisphere: 2a : 3a : North America: 2b : 3b : Eurasia: 2c : 3c Figure 2: These plots show time series (updated daily) of snow cover extent (million km 2) over (a) Northern Hemisphere land areas (excluding Greenland), (b) North America, and (c) Eurasia.Snow cover is assumed to be present in grid cells where the daily snow depth in the CMC. The maps show snow cover, expressed as the number of days a grid cell is snow covered for each month for each year. On the maps, areas with longer than average snow cover duration are indicated in blue (positive anomalies). Areas with shorter than average snow cover duration are indicated in red (negative anomalies).
Snow cover is an extremely important storage component in the water balance, especially seasonal snowpacks in mountainous areas of the world. Though limited in extent, seasonal snowpacks in the Earth ’s mountain ranges account for the major source of the runoff for stream flow and groundwater recharge over wide areas of the midlatitudes. Snow cover highlights the calderas and volcanic cones that form the northern and southern ends of Onekotan Island, part of the Russian Federation in the western Pacific Ocean.

The snow cover mapping in Himachal Pradesh from October last year to May this year showed a marginal fall of about 0.72 per cent in the total area as compared to the previous year, a government. This icon serves as a link to download the eSSENTIAL Accessibility assistive technology app for individuals with physical disabilities. It is featured as part of our commitment to diversity and. Scientists improve storm forecasting, study global snow cover and its effect on climate, glaciers, and water supplies around the world. The study includes physical properties of the material as it changes, bulk properties of in-place snow packs, and the aggregate properties of regions with snow cover.
Snow cover also keeps the soil moist, so if the snow melts away earlier in the spring, the soil may dry out sooner, which can stress plants and increase the risk of wildfire. 1 About the Indicator This indicator tracks the area covered by snow since 1972, based on maps generated by analyzing satellite images collected by the National Oceanic. Snow and ice cover most of the Earth’s polar regions throughout the year, but the coverage at lower latitudes depends on season and elevation. High-altitude landscapes such as the Tibetan Plateau and the Andes and Rocky Mountains maintain some amount of snow cover almost year round. Snowmelt also affects water supplies, and decreasing snowpack may decrease water supplies in areas around the world that rely on spring runoff. Although fall and winter snow cover has remained fairly consistent over the past 40 years, spring and summer snow cover is typically more important in influencing water supplies.
Snow cover extent in the U.S. and the rest of the Northern Hemisphere is observed from satellites. Current and recent snow-cover graphics are available here. Archived fractional snow cover for the U.S. (percentage of snow cover at a location, as opposed to snow/snow-free) is available on the Interactive Maps page but is no longer current. Snow Cover.
