| Summary: | 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_.nc, where is degrees of warming ... : Supplement to: Chadburn, Sarah; Burke, Eleanor J; Cox, Peter; Friedlingstein, Pierre; Hugelius, Gustaf; Westermann, Sebastian (2017): An observation-based constraint on permafrost loss as a function of global warming.
