Simulation of the Decadal Permafrost Distribution on the Qinghai‐Tibet Plateau (China) over the Past 50 Years
Decadal changes in permafrost distribution on the Qinghai‐Tibet Plateau (QTP) over the past 50 years (1960–2009) were simulated with a response model that uses data from a digital elevation model, mean annual air temperature (MAAT) and the vertical lapse rate of temperature. Compared with published...
