Permafrost-Detektion mittels Fernerkundung und Geophysik auf dem tibetischen Plateau
In this study we combine geophysical techniques in the form of microwave remote sensing and Electrical Resistance Tomography (ERT) interferometry to study the extent of permafrost in the catchment of Lake Nam Co on the Tibetan plateau. Interferometric Synthetic Aperture Radar (InSAR) is a powerful t...
