Factors aﬀ ecting soil temperature as limits of its spatial interpretation and simulation 7 AUPO Geographica Vol. 45 No. 1, , pp. Table 1 Systematic summary of the key ﬁ ndings of factors inﬂ uencing the soil temperature. Interactios SOLAR RADIATION State of the atmosphere Anthropogenic in ﬂ uence Pressure gradients and wind: Rettig (); Hanks et . Soil temperatures are related to air temperature and rainfall on the current day and preceding days, and this can be expressed in a non-linear relationship to provide a weighted value for the effect of air temperature or rainfall based on days lag and soil depth. The weighted minimum and maximum air temperatures and weighted rainfall can then be combined with latitude and a .

The National Observatory of Athens (NOA), provided soil temperature measurements since The observatory is situated on a hill in the center of Athens (latitude=°N, longitude=°E and altitude= m).Cited by: Soil temperature is an important property that is essential for many soil processes and reactions that may include, but are not limited to, water and nutrient uptakes, microbial activities, nutrient cycling, root growth, and many other processes (Doran and Smith, ).Soil temperature properties change by the radiant, thermal, and latent energy exchange processes that take place at the soil.
An assessment of surface soil temperature products from numerical weather prediction models using ground-based measurements Thomas R. Holmes,1 Thomas J. Jackson,1 Rolf H. Reichle,2 and Jeffrey B.
Basara3 Received 10 February ; revised 21 November ; accepted 12 January ; published 25 February Cited by: The observations on soil moisture at two depths, viz. 0–25 and 0–50 cm, surface temperature, and temperatures at 1, 5 and 10 cm depths are analysed.
The relationship between the soil moisture and the temperature variability in time is examined as a Cited by: 1 An Assessment of Surface Soil Temperature Products 2 from Numerical Weather Prediction Models Using 3 Ground-based Measurements 4 5 Thomas R.H.

The range of maximum daily soil temperatures at a depth of 5 cm can be seen in Figure 3(a). The range of maximum temperatures across. soil moisture and surface temperature observations. Field measurements of surface temperature have been used for validation of satellite-retrieved surface temperatures (Lakshmi et al., ; Prince et al., ; Lakshmi and Susskind, ).
Our work is motivated by the following problem: in practice, microwave sensors that detect and retrieve. Soil temperature fluctuates annually and daily affected mainly by variations in air temperature The impact of water content upon estimated soil temperature can be observed by viewing results for this range of thermal diffusivities.
Figure 3 is based on research cited by of deVries (, Scripta Book Co., Washington, DC. Farouki, O.T. This next chart shows the results of all the temperature probes.
The erratic probe is the daily temperature fluctuations. The light blue and green curves are the ft deep probes (dry and control). These follow the air temperature the most closely, but are still very moderate compared to the air temperature fluctuations.
1 An Assessment of the Variability of Soil Temperature at the Catchment Scale Martinez, C.1, G.R. Hancock1, T. Wells1, and J.D. Kalma2 1School of Environmental and Life Sciences, The University of Newcastle, Australia 2School of Engineering, The University of Newcastle, Australia Email [email protected]  Temperature changes in the soil are essentially driven by the radiative balance, the sum of net short wave solar radiation and net long wave thermal radiation directed toward the soil surface.
This net radiation flux is distributed over 1) sensible heat from the surface into the air that is driven by the advection of turbulent air above the surface, 2) latent heat when it is used to. Soil temperature, soil moisture, skin temperature and 2-m air temperature are examined from both ground observations and the offline community land model (CLM4).
Two-layer soil moisture and three-layer soil temperature observations from six-year (–) ground measurements at the Lamont, Oklahoma site supported by the Atmospheric Radiation Measurement. HYDRUS-1D considerably underestimated the soil temperature of the upper layers in the frosty period when the average air temperature was −°C between 27/12/ and 04/01/, while the average observed and calculated T soil was − and −°C, respectively, at 5 cm depth.
During the winter period, all models overestimated the trends of temperature changes and. Observatory ) were chosen to Both snow depth and soil temperature measurements (at. The soil frost depth was estimated using a soil frost model.
Results showed that due to a. The daily soil temperature for clayey soil ranges from ℃ – ℃ with a simple mean of ℃; ℃– ℃ for sandy soil and ℃ – ℃ for loamy soil.
Song Y T, et Sci Bull March () Vol No.8 Figure 3 Changes in mean daily air and soil temperatures (C) from 23 April to 1 September (a) Air temperature at 10 cm above soil surface, (b) soil temperature at 5 cm below soil surface, and (c) soil temperature at the 2- and 5-cm depths.
The array facilitates multiple measurements of detailed temperature profiles. These measurements are capable of detecting the effect of soil conditions such as tillage, layering, or water content on the flow of heat at a resolution of centimeters.
The GLACE2 experiment. The multi-model experiment GLACE2 was designed to isolate the contribution of realistic soil moisture initialization to forecast skill of temperature and precipitation at lead-times of up to 60 days (Koster et al.

Air temperature can be used to determine soil temperature and the exchange of gasses between soil and atmosphere.soil temperature (depth of 15 cm) using the daily mean air temperature from the previous day and a cosine function of Julian date (R 2 = ; SEM =.
Variations in soil temperature at depths have been investigated in different parts of Southern Nigeria. Measurements were carried out at different lithologies and at different times with the aid of a soil thermometer over a three-week period. Readings were taken in three major lithologies which include clay, sand and sandy loam.
