Resumen:
A regional-extension permafrost distribution model was achieved, including locally adjusted data. It discriminates between permafrost in debris or loose sediments from rock-permafrost and ice bodies. The final model is a combination of two separate occurrence probability models: a) mean annual air temperature-terrain ruggedness model and, b) mean annual air temperature-potential incoming solarradiation model. Possible permafrost, in coarse debris, is expected between 4200 to 5700 m asl (MAAT from -3º to -18ºC) and covers a surface of aprox. 1200km2 in the Andes.
