Climate models

In this section you can find useful Geospatial Layers produced by the Global Terrestrial Network for Permafrost (GTN-P) or related to permafrost studies.

The downloads are provided as different file types:

    • Keyhole MarkUp Language files (KML): a XML notation for expressing geographic annotation and visualization within Internet-based, two-dimensional maps and three-dimensional Earth browsers. KML was developed for the use with Google Earth.
    • ESRI Shapefile: a (mostly) open specification for data interoperability among ESRI and other GIS software products, spatially describing vector features: points, lines, and polygons. (Download QGIS, a free and open source geographic information system, here .)
    • Comma-Separated Values (CSV): tabular data (numbers and text) in plain-text form.

Projected climate change

Climate models use quantitative methods to simulate the interactions of the atmosphere, oceans, land surface, and ice. They are used for a variety of purposes from study of the dynamics of the climate system to projections of future climate.
