  Evaluation and Assessments of Borehole Paleothermometry Methods for Inferring Past Climate Change
  Author(s): Wang Chen*
  
  The problem of inferring Ground Surface Temperature History (GSTH) from borehole temperature-depth data, like virtually every other geophysical inverse problem, is characterized by instability due to presence of noise. Due to the different ways in which the problem may be parameterized and optimized the solution is method-dependent. In this work we attempt to analysis the results obtained by four methods, including currently widely used Functional Space Inversion (FSI) and Singular Value Decomposition (SVD), and also new developed Method of Fundamental Solutions (MFS), and Tikhonov method. All of four methods are based on the theory of 1-D heat conduction. To assess the effectiveness of various methods, synthetic ground temperature profile data with noise were prepared and used to compare different methods. We analyse five mathematical models describing the GSTH: .. View More»
