READ MOREIn a new paper just published in Global Change Biology, we provide the first-ever global maps of soil temperature (0 -15 cm) at a 1 km² resolution, based on the global SoilTemp database of over 8500 in-situ soil temperature time series.We show that over the year, soils in cold and/or dry biomes are on average 3.6°C warmer, whereas soils in
READ MOREThere are often talks of ground temperature being a constant 55F at 6ft or so. But some also said that in very hot and dry climate, say Arizona desert, temperature is much higher at the same depth. It is strongly dependent on surface conditions, precipitation, ground cover, etc. A depth of 4 feet is not sufficient to insulate from surface
READ MOREBasically, the profile of the soil temperature depends on the depth below the ground surface. Temperature layers deeper below the ground react less sensitively to temperature fluctuations of the air temperature. This is shown in Figure 1: Directly below the earth''s surface, the earth''s soil temperature directly follows the outside air
READ MOREOne possible way of assessing soil thermal properties is the analysis of soil temperature variations versus depth Fourier''s law, Q = − λ d T / d z {displaystyle Q=-lambda dT/dz,} where Q is heat flux or rate of heat transfer per unit area J·m −2 ∙s −1 or W·m −2, λ is thermal conductivity W·m −1 ∙K −1 ; dT / dz is the

READ MOREYou''re right, around 10 meters (about 32 feet), the temperature of the soil takes on the average temperature of that location throughout the year. Below that depth, the temperature stars gradually increasing as one drills deeper into the crust. Here''s a derivation of that value, generally known as the "geothermal gradient".
READ MOREIn December, the highest ground temperature was at a depth of 6 m and it was 11.1 °C, in January at a depth of 7 m and it was 10.4 °C, and in February at a depth of 8-9 m and it was 9.9 °C
READ MORESimulated soil temperature profiles at various times in the year for a soil with average temperature of 10 °C for all depths and an amplitude of 10 °C for the annual oscillation at the soil surface. We can also use Eq. 13-4 to visualize soil temperature versus depth at defined times. During the winter, the coldest temperature is at the soil
READ MORESoil Temperatures. All Kansas Mesonet stations measure soil temperature at a minimum of two depths. This provides insight into what is going on below the surface and is vital for agriculture. Data has been recorded at the 13 original KSRE stations since the mid-1980s. At that time, soil temperatures were measured under bare soil at 2 and 4 inches.
READ MOREHere, we provide global maps of soil temperature and bioclimatic variables at a 1-km2 resolution for 0–5 and 5–15 cm soil depth. These maps were created by calculating the difference (i.e. offset) between in situ soil temperature measurements, based on time series from over 1200 1-km2 pixels (summarized from 8519 unique temperature sensors

In our case, for distance, we are talking about depth in the Earth, and the center of the Earth is very hot — about 5000°C. The surface, instead, is quite cool at 15°C
