Rapid Reconnaissance of Geothermal Prospects Using Shallow Temperature Surveys

摘要

In this final report, an Annual Wave Correction Model is constructed. The model makes rapid reconnaissance of geothermal prospects using shallow temperature surveys a reality. The model is tested using data previously obtained at the Coso KGRA. Inputs are surface meteorological data gathered during a 15 month period, soil thermal diffusivity data derived from previous studies in this series, and surface roughness and albedo measured at the site. Computations are made to determine the normal, 1.e., non-anomalous temperatures at 2-m depth, for the period 22-24 September 1977, for each of the 102 stations at Coso. The observed 2-m temperatures recorded at these stations during this period and corrected for elevation are compared to the normal temperatures, and a residual anomaly map has been drawn. The map compares favorably to the mean annual temperature map for the same area.
