Data Access & Tools
Access and download NOAA@NSIDC data using a web browser, or through a command line utility such as WGET, or using programming languages such as R or Python.
Type:
service
Browse Arctic- and Antarctic-wide changes in sea ice. View daily and monthly averages of extent and concentration. View time series graphs of Arctic and Antarctic sea ice.
Display browse images for five different parameters from three different NOAA@NSIDC Arctic sea ice products in a spreadsheet-like format.
See how Arctic/Antarctic sea ice extent changes throughout the calendar year using a customizable graph in a web browser. Compare extents for all years since 1979, and click on any point in any year's trajectory for a map of daily sea ice concentration.
Access georegistered images for data layers from select NSIDC data products. Use OGC protocols (WMS, WFS, and WCS) through HTTP URLs or OGC-compatible clients (ArcMap, QGIS, Google Earth) to access the data.
Customization Capabilities:
data reformatting
reprojection
spatial subsetting
temporal subsetting
variable subsetting
Visualize changes in Arctic air temperatures, frozen ground, sea ice concentration and age, snow cover duration, vegetation greenness, and water vapor. Animate maps and time series graphs.
Analyze monthly or daily sea ice concentration and extent. Plot monthly extent anomalies. Display concentration trend images based on date, climatology, and trend range.
View animated maps of monthly sea ice extent, concentration, anomalies and trends for the Northern and Southern Hemisphere.
Compare sea ice extent for any two days or months between 1979 and present.
