An efficient time-dependent equation for predicting ground surface temperature devised by Bhumralkar (1975) and Blackadar (1976) is tested against a 12-layer soil model and compared with five other approximate methods in current use. It is found to be generally superior if diurnal forcing is present and very much superior to the use of the insulated surface assumption. An analogous method of predicting ground surface moisture content is presented which allows the surface to become moist quickly… 

Inclusion of a Simple Vegetation Layer in Terrain Temperature Models for Thermal IR Signature Prediction

A time-dependent energy budget model was designed to enable the prediction of the temperature of terrain scene elements that contain a simple layer of vegetation and to diagnose the effect of

Bare-ground surface heat and water exchanges under dry conditions: Observations and parameterization

A simplified land-surface parameterization is tested against bare-soil data collected during the EFEDA experiment conducted in Spain in June 1991. A complete data set, made up of soil properties as

Class—A Canadian land surface scheme for GCMS. I. Soil model

A new GCM land surface scheme is introduced, incorporating three soil layers with physically based calculations of heat and moisture transfers at the surface and across the layer boundaries.

Investigating the Sensitivity of a Land Surface Scheme's Simulation of Soil Wetness and Evaporation

A suite of sensitivity experiments focusing on leaf area index (LAI) was conducted within the GSWP framework using one land surface scheme. First, the LAI was changed from the original 1x1 resolution

A model of the ground surface temperature for micrometeorological analysis

Micrometeorological models at various scales require ground surface temperature, which may not always be measured in sufficient spatial or temporal detail. There is thus a need for a model that can

Estimation of regional surface resistance to evapotranspiration from NDVI and thermal-IR AVHRR data

Abstract Infrared surface temperatures from satellite sensors have been used to infer evaporation and soil moisture distribution over large areas. However, surface energy partitioning to latent

A Model to Predict Surface Temperatures

A model to predict the surface temperature of a variety of surfaces is described. The model solves the surface energy balance equation iteratively, using only standard meteorological data. Since

Infiltration, soil moisture, and land-use relationships with reference to surface runoff

The major development in this paper is a method for determining rates of water movement within the soil profile on watersheds under natural conditions. The method uses rainfall rates or infiltration

Radiative temperature in the heat balance of natural surfaces

A Linke-Feussner radiometer was used to measure the radiative temperature of natural surfaces, with small errors caused by the divergence of radiative flux and by its angular variation. On typical

Numerical Experiments on the Computation of Ground Surface Temperature in an Atmospheric General Circulation Model

Abstract The Rand two-level general circulation model has been integrated to compute ground surface (bare land) temperature by solving: 1) the interface heat balance equation without soil heat flux;

Momentum, mass and heat exchange of vegetation

Vegetation is treated as a complex surface roughness to which the transfer of mass or heat encounters greater aerodynamic resistance, γP, than the transfer of momentum, γD. The excess resistance (γP
