PERICLIMv1.0: A model deriving palaeo-air temperatures from thaw depth in past permafrost regions

PERICLIMv1.0 is a simple modelling scheme that allows to derive palaeo-air temperature characteristics associated with relict periglacial features indicative of the palaeo-active-layer thickness, and thus it is supposed to be used by periglacial geomorphologists interested in reconstructions of Quaternary palaeo-environments. It principally builds on an inverse solution of the Stefan equation, which is among the most commonly used analytical tools to estimate the thickness of the active layer. This way it deduces thawing-season temperature conditions, which it further converts into annual as well as freezing-season air temperature attributes based on the assumed annual air temperature range.
