We analyzed temperature data of nine SW U.S. caves using Fourier analysis to characterize thermal behavior, and line graphs to identify optimal times of detection in the thermal infrared. This work furthered our understanding of cave thermal behavior.

This study aims to increase our understanding of cave thermal behavior and to identify optimal times for detecting caves using thermal remote sensing. Techniques developed for Earth caves will ultimately be applied to locating subterranean cavities on the

The goal of this project is to improve capabilities for identifying caves on Mars, through: 1) studies of thermal properties and imaging of terrestrial caves; 2) computer modeling of cave thermal properties; and 3) GIS-aided analysis of Mars imagery for cave-like structures.

... This hypothesis went untested for over 30 years. Over the last decade, researchers have re-examined cave detection in the thermal infrared and have made significant advances (e.g., [1,47,[57][58][59][60]). ...
... The thermal environment within caves also warrants consideration, with its consistency offering potential benefits. Studies on the thermal properties of very dry caves on Earth indicate that the temperatures inside the caves can be roughly estimated as the local mean annual surface temperature [20]. The thermal skin depth of the Martian regolith, that is the depth at which diurnal and seasonal surface temperature variations are attenuated by a factor of the mathematical constant e, is estimated in the order of several centimeters [21]. ...
