Methods of statistical evaluation of data from long-term measurements of soil temperature profile using open-source tools

This paper describes the statistical evaluation of collected data from measuring the temperature of the soil profile to determine the thermodynamic parameters of the soil thermal collector. Data analysis is aimed at determining the periodicity of changes in temperature, heat transfer parameters depending on the depth, thermal conductivity and accumulation characteristics of soil thermal collector. To save the measured data, there was used relational database server MySQL, for the data evaluation there were used numerical libraries for data processing of Python programming language, for data visualization there was used application Scidavis and to post data to a web site there were used modules modpython and matplotlib of the Python programming language.
