3 dni temu · Analyze monthly-averaged or daily sea ice extent and concentration via interactive maps. Plot monthly ice extent anomalies, map sea ice concentration anomalies, and more.
It provides consistently processed daily ice extent and concentration images and data since 1979. Daily extent images show ice extent at concentrations greater than 15% for a given day with an outline of the typical extent for that day based on a 30-year (1981-2010) median (orange line).
Visualize sea ice extent (area of ocean with at least 15 percent sea ice concentration) data for the Arctic and Antarctic. View and compare sea ice extent data for any year or any combination of years from 1979 to present (including near-real-time daily data).
30 paź 2024 · Color-coded map of the daily sea ice concentration in the Northern Hemisphere for the indicated recent date along with the contours of the 15% edge during the years with the least extent of ice (in red) and the greatest extent of ice (in orange) during the period from November 1978 to the present.
Sea ice extent provided by the National Snow and Ice Data Center (NSIDC) is available from 1979–2024 for the Globe, Northern Hemisphere, and Southern Hemisphere. Snow cover extent provided by the Rutgers University Global Snow Laboratory (GSL) is available from 1967–2024 for the North America + Greenland, Northern Hemisphere, Eurasia, and ...
This app displays the monthly mean sea ice extent for the Arctic and Antarctic along with the historical median extent. Additionally, graphs are used to visualize the minimum and maximum extent for each year (top), and the monthly time series for each year (bottom).
The index covers both the sea-ice extent and area over the last 40+ years and is continuously updated to present time. It consists of an updated series of graphs (.png) visualising the trends and evolution of sea ice at hemispheric, global and regional scales.
