| contents | A globally applicable relationship between air temperature and permafrost areal fraction was derived using reanalysis air temperatures and the historical IPA permafrost map. This relationship defines a maximum, minimum and mean permafrost fraction at a given air temperature. Future air temperatures were estimated for a particular global mean warming, using the observed Arctic amplification and a pattern-scaling approach with the 1986-2005 mean air temperatures as the baseline. Here we show the estimated permafrost map, using our method, from the time of the IPA map ('historical' = 1960-1990), along with the estimated future permafrost maps using pattern-scaled air temperatures, for a range of global stabilisation temperatures (between 1 and 6 degree C above pre-industrial levels (1850-1900)). For each global mean air temperature there is a maximum, minimum and mean permafrost extent according to our permafrost-air temperature relationships. The file naming is as follows: map_<deg><type>.nc, where <deg> is degrees of warming above pre-industrial climate, and <type> is one of max, min, or mean, indicating maximum, minimum or mean permafrost extent. The maps are global at 0.5 degree resolution. |
