Webthe upper soil heat flux estimate (Surface HF 1) can be seen in Fig. 3. The robustness of the overall method is demonstrated by the fact that the difference between the two is less than 10%. Fig 3 Surface heat flux as determined by the heat flux calculated by the top and middle cables (HF 1) and by the middle and bottom cables (HF 2 ... Webat 2, 4, 7, 10, and 15 cm below the surface of a bare field soil, over a 1-week period at 20-min intervals. The conductive heat and liquid moisture fluxes were calculated for the soil layer 7-10 cm below the surface, and the water vapor flux was then determined from both the energy transfer and mass transfer equations. Water vapor flux in this ...

Soil temperature depends on the ratio of the energy absorbed to that lost. Soil has a mean annual temperature from -10 to 26 °C according to biomes. Soil temperature regulates seed germination, breaking of seed dormancy, plant and root growth and the availability of nutrients. Soil temperature has important seasonal, monthly and daily variations, fluctuations in soil temperature being much lower with increasing soil depth. Heavy mulching (a type of soil cover) can slow the w… WebThe contribution of plant transpiration to the land surface heat flux is negligible during the dormancy period. ...
