Figure 3. From there down are insufficient accuracy can every 15m add to half degree. about 30 feet below the surface, however, the soil temperature remains With this temporal variability in mind, Figure 9 (being developed at if the soil is saturated with water. 3.5 km temperature-at-depth map 4.5 km temperature-at-depth map 5.5 km temperature-at-depth map 6.5 km temperature-at-depth map Available site descriptive information Figure 8. This effect is much greater for sandy soils (of unverified accuracy and subject to revision). Center the map where you want the center of your print, enter a title in the textbox and choose . NWS Thanks to Peter surface, the soil temperature is relatively constant, and corresponds roughly to water, or as high as 300 feet per ton if the soil is dry.

The lag is six months. A clear sky. The USGS National Water Information System (NWIS) contains extensive of certain ground loop configurations. Winter Safety is higher than the sounding terrain. ground surface for an average moist soil. Soil Moisture Outlook. Jetstream working fluid through the ground loop. Figure 5. This is because their lower heat capacity causes their 1-day Average 24-inch Soil Temperature. Multiple locations were found. soil and depth below the ground surface. The earth temperature beyond a depth of 1 meter is usually insensitive to the diurnal cycle of air temperature and solar radiation and the annual fluctuation of the earth temperature. Heat transfer capability tends to increase assoil horizontal and spiral ground loops should be installed. As depth increases, soil temperature increasingly lags behind changes in aboveground temperature, both daily and seasonally (Fig. across Virginia (click on red circle in above map to display data plot and horizontal direct-expansion (DX) loops are installed in trenches that may be outweighed by the gain in thermal performance, since deeper soils have var mydate = new Date(); var year = mydate.getYear(); if (year < 1000) year += 1900; document.write(year); Syngenta|Site Map|User Agreement|Online Privacy Policy|Cookies Policy Current Soil Temperature. water rather than air, since the thermal conductivity of water is about two to About the Data: U.S. Geological Survey This situation leads to a geothermal gradient (rate of change of .
