In order to begin the research process Fu and Rich decided to study at the Rocky Mountain Biological Laboratory in Gunnison County, Colorado. Eleven Hobo soil temperature senors were buried in many different locations around Gunnison County, Colorado. They then logged temperature by each hour. After the data was collected, Fu and Rich began creating insolation and temperature maps to display their findings. The insolation data was inserted into the TopoView model. Most weather stations do not record soil temperature, so this study is valuable. The results determined that soil temperature varies with position in the topographic landscape. It was concluded that during the summer high spatial resolution for temperature was represented. When snow is present the spatial resolution lowers. This study is valuable because using solar radiation models for soil temperature calculation is just one of the abilities. The study mentions that water balance is also available to study with insolation data and solar radiation models.
This model displays soil temperature (in degrees Celsius) with a legend that has the different temperatures in relation to color. The lighter the color on the legend the higher the temperature at 20cm depth. These soil temperatures were collected daily with a minimum and maximums.
