Modeling of daily temperature fluctuations in the root layer of sandy forest soils

The problem of analyzing the impact anthropogenic carbon dioxide on environment necessitates study soil dynamics. Thermal parameters (heat capacity, thermal conductivity, and diffusivity) play an essential role in processes CO2 transfer production. Considering that these depend texture other various factors, mathematical description regime soils a specific area is relevant task. There are many ways to estimate diffusivity coefficient, none which universal. In this paper, least squares method used temperature wave attenuation coefficient (thermal for sandy forest Eastern Fennoscandia, under assumption medium uniform. Also, estimating amplitude daily fluctuations proposed practical recommendations measurements given.
