Inference o f Ground Surface Temperature History from Subsurface Temperature Data: Interpreting Ensembles o f Borehole Logs
Abs t rac t -Ground surface temperature histories (GSTHs) inferred from borehole temperaturedepth (T-z) data are often degraded, to a various extent, by random or systematic noise in the T-z data and in the measurements of thermophysical properties of the earth. To minimize the effects of noise, and hence improve the fidelity of the inferred GSTH, a plausible approach is to perform a simultaneo...
متن کاملGround 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 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 ...
متن کاملSimultaneous Tuning of Water Vapour and Atmospheric Temperature for Determination of Sea Surface Temperature from AVHRR
A novel physics-based method for determination of sea surface temperature (SST) from AVHRR is explained in detail. Starting from the equation of radiative transfer in the mean value approximation, we use variational calculus to derive an expression relating the difference between the radiance calculated using a first guess atmospheric profile and the observed satellite radiance (∆I), to the cor...
متن کاملImpact of borehole depths on reconstructed estimates of ground surface temperature histories and energy storage
Estimates of ground surface temperature changes and continental energy storage from geothermal data have become well-accepted indicators of climatic changes. These estimates are independent contributions to the ensemble of paleoclimatic reconstructions and have been used for the validation of general circulation models, and as a component of the energy budget accounting of the global climate sy...
