Abstract
In this article, the application of the Ångström method in estimating the thermal diffusion parameter in an example of natural biological environment is described. The present study is based on measurements performed in forest soils. The main advantage of the suggested procedure is that it does not need the collection of samples of the soil for a later study in the laboratory. Collecting such data is typically very laborious and requires the preservation of the natural content and structure of all elements of the soil profile in the samples, such as organic components, soil parts, or rocks. The harmonic time runs necessary to implement the Ångström method were computed with the short-time Fourier transform. The obtained results, compared with reference values taken from literature, confirm the accuracy of the proposed methodology.
