Modeling of Ground Temperature as a Function of Some Environmental Factors

In spite of the importance of the temperature of the ground, only little model has been established for the earth temperature at 5cm and 10cm below the ground surface. This piece of research work is useful in generating the temperature of the earth at these depths for many years to come as long as other environmental factors are available for these years. The environmental factors used in this work, were recorded and obtained from Nigeria Meteorological service (NIMET), SPSS was used for the data analysis and the outputs was discussed in detail to extract the equations of the earth temperature at both depths. MATLAB programming language was used to generate the computed values of the earth temperature from the equations obtained to test its validity. The observed and computed data were compared and subjected to statistical test for validation. The test showed no significant difference between the observed and the computed data. Information on ground temperature is important for many construction projects, installation of underground pipes and cables, survival and nutrient distribution in plant.
