Ensembles 850 hPa & precipitation · SCHMIDT
Each ensemble model calculates many possible outcomes from slightly different initial conditions. Thin lines represent its members and the stronger line their mean. A wider spread indicates greater uncertainty. Compare direct NOAA GEFS/AIGEFS, ECMWF IFS ENS/AIFS ENS and ECCC GEPS data when the corresponding downloads have completed.
The first visit to a new point may require collection time. This section shows the actual status and available range, without inventing members or values.
Weather satellite at the glacier · SCHMIDT
Inspect cloud cover using available visible and infrared channels. Image times and geographic coverage depend on the satellite; not every geostationary satellite covers polar regions. Cloud images do not measure glacier thickness.

Glaciers by country and territory
Why glaciers matter: water, climate and changing mountains
A glacier is a body of snow and ice that flows over land. Snow accumulation adds mass; melting and ice loss remove it. A snowy week is therefore only one part of a much longer balance. NSIDC: glaciers.
Glacier melt contributes to river flow and freshwater supply. Ice stored on land also matters for sea level when it reaches the ocean. Changing ice affects mountain landscapes and the ecosystems connected to meltwater. NSIDC: why glaciers matter.
Use the country pages to move from a broad view to an individual observation record. Then open nearby mountain or ski-resort forecasts to examine temperature, precipitation and wind. These forecasts describe short-term weather; the glacier history describes measured change over years.
How to read glacier mass balance and retreat
Annual mass balance, m w.e. A positive value means net mass gain during the reported hydrological year; a negative value means net loss. Metres of water equivalent express the mass as an equivalent water layer. They are not a direct measurement of metres of ice thickness at one point. WGMS: mass-balance units.
Front variation, metres. This measures movement of the glacier terminus between the stated dates. Negative values mean retreat, positive values advance. A measurement interval may span several years: the chart preserves the interval and does not invent annual values.
Missing years and different methods. Gaps remain gaps. Winter and summer balances are displayed only when reported. Glacier outlines are dated observations of shape, while a mass-balance series measures change; combining them does not turn the map into a live ice forecast.
Planning a mountain visit. Links to nearby destinations show approximate straight-line distances, not routes across ice. Check the destination’s forecast and current local operating information before choosing a ski area or mountain itinerary.
