A continuous variation of thermal energy, presented as air temperature, is registered by a ground-based network. However, an insufficient number of stations does not allow for the representation of the spatial distribution of these values

The AA. report the results of a field study that was designed to test the feasibility of using ground-based LIDAR to map the topography of a sand dune in high spatial resolution. They present a surface topography model obtained from a scanning

Permafrost sounding (2003-2004) in the source area of the Yellow River, China
The project aims at mapping the area underlain by permafrost and simulating the ongoing degradation of permafrost due to climatic warming. This paper presents the results of the field observations undertaken in 2003-2004. The fieldwork involved
monitoring of ground surface temperatures and sounding of seismic stratigraphy, which were undertaken at several sites in the source area mainly along the R214 road that connects Xining and Yushu. The elevation of the measurement sites varies from 3260 m
