Glaciers & ice

Glaciers, Snow & Ice Data

Global glacier inventories, snow cover, sea ice extent, and frozen ground datasets from NSIDC, GLIMS, and MODIS sources.

Each dataset page captures official source links, access notes, and related GIS workflows.

Official sources and direct access

Mixed delivery

Pages combine official portals, direct downloads, and task-focused usage guidance in one canonical URL.

GEO coverage

Task-first content

Intros, FAQs, and workflows are written to answer real “where do I download…” searches.

Glacier and ice pages help cryosphere researchers find global glacier outlines, snow cover time series, sea ice extent, and lake/wetland data for climate change monitoring.

These datasets pair naturally with ArcticDEM, permafrost, and climate data for comprehensive high-latitude and cryosphere analysis.

Category directory

Category pages aggregate the most useful entry points first, then push visitors into detailed dataset pages with richer steps and FAQ sections.

Recommended glacier workflow

How to choose a source

  • Use the Randolph Glacier Inventory for a complete global glacier outline dataset with area and volume attributes.
  • Use MODIS Snow Cover for daily to monthly snow extent monitoring.
  • Use NSIDC Sea Ice data for Arctic and Antarctic sea ice extent and concentration analysis.
  • Combine with ArcticDEM and climate data for glacier mass balance studies.

Category FAQ

Category FAQ

What is the most comprehensive free glacier dataset?

The Randolph Glacier Inventory (RGI) provides the most comprehensive global glacier outlines, covering over 200,000 glaciers with area, length, and classification attributes.

How frequently is snow cover data available?

MODIS Snow Cover provides daily global snow extent at 500m resolution from 2000 to present, with 8-day composites for cloud-free analysis.
