Abstract The memories of soil moisture (SM) and soil temperature (ST) modulate the effect of land surface on climate prediction on monthly and longer timescales. Based on a Lagrangian‐based understanding of SM and ST memories, this study explores the characteristics of SM and ST memories using ERA5‐Land reanalysis data, observations ...

Soil atmosphere and soil temperature
1987Plant roots, soil microorganisms and fauna are consumers of oxygen and producers of carbon dioxide. This gives rise under ordinary conditions to the well known carbon dioxide concentration gradient from about 50 000 ppm (5%) in soil pores to a little over 300 ppm in the general atmosphere.

The temporal and spatial patterns of soil temperatures in Nigeria are examined. Because of the effect of latitudinal position on air temperatures, soil temperatures generally increase with increasing distance from the coast. There is however an exception to this general pattern on the Jos plateau, where, because of the significant effect of elevation ...

1. The soil temperatures in Egypt at a number of depths have been recorded by means of continuous recording thermometers. In general, the records show that the amplitude of the temperature wave at the surface of the soil is considerably greater than the air temperature wave.

ABSTRACTTwo methods are described for simulating soil temperatures in the field that have been used for student experiments in a beginning soil physics laboratory. The first involves a simple numerical procedure that assumes soil thermal properties are constant.

A soil temperature demonstration
Journal of Agronomic Education, 1980ABSTRACTAn exhibit was constructed to demonstrate the effects of soil moisture on the heat capacity and thermal conductivity of two different soils. Four soil columns were fitted with thermistors at depths of 0 to 1, 5, and 10 cm below the soil surface. Half the columns were saturated with water and the other half were left air‐dry.

This paper develops a method for computing temperatures at a point in a soil from surface temperatures. The method is adaptable to the irregular fluctuations in temperature ordinarily found in nature as well as to ideal cases. The temperature at a point in the soil is expressed as a weighted function of antecedent temperatures at the surface.
