Ground vs. surface air temperature trends: Implications for borehole surface temperature reconstructions
[1] We have analyzed the relationship between surface air temperature (SAT), ground surface temperature (GST), and snow cover (SNC) over the terrestrial Northern Hemisphere based on general circulation model (GCM) simulations using GISS modelE forced with the observed SST and radiative forcing changes from 1951–1998. While SAT is the dominant influence on GST during the warm-season, it explains...
متن کاملPaleoclimatic reconstructions in western Canada from borehole temperature logs: surface air temperature forcing and groundwater flow
Modelling of surface temperature change effect on temperature vs. depth and temperature-depth logs in Western Canada Sedimentary Basin show that SAT (surface air temperature) forcing is the main driving factor for the underground temperature changes diffusing with depth. It supports the validity of the basic hypothesis of borehole temperature paleoclimatology, namely that the ground surface tem...

متن کاملMerging Surface Reconstructions of Terrestrial and Airborne LIDAR Range
Recent advances in range measurement devices have opened up new opportunities and challenges for fast 3D modeling of large scale outdoor environments. Applications of such technologies include virtual walk and fly through, urban planning, disaster management, object recognition, training, and simulations. We note that the scan line ordering of terrestrial LIDAR range data is conducive to stream...
متن کاملSurface Temperature Determination from Borehole Measurements : Regularization and Error Estimates
The authors consider the problem of determining the temperature distribution u(x, t) on the half-line x 0, > 0, from measurements at an interior point, for all > 0. As is well-known, this is an ill-posed problem Using the Tikhonov method, the authors give a regularized solution, and assuming the (unknown) exact solution is in H(R),a > 0 They give an error estimate of the order for e 0, where e ...
