Comparisons of Interception Loss from Tropical and Temperate Vegetation Canopies
Publisher: American Meteorological Society
Abstract: A multilayer crop model is used to investigate interception loss from oak, pine, wheat and grass canopies. It is shown that the evaporative properties of the full oak canopy are similar to those of the evergreen tropical ...
Testing the Simple Biosphere Model (SiB) Using Point Micrometeorological and Biophysical Data
Publisher: American Meteorological Society
Abstract: The Simple Biosphere model (SiB) of Sellers et al. (1986) was designed for use within General Circulation Models (GCMs) of the earth's atmosphere. The main objective of SiB is to provide a biophysically realistic description ...
A Global Climatology of Albedo, Roughness Length and Stomatal Resistance for Atmospheric General Circulation Models as Represented by the Simple Biosphere Model (SiB)
Publisher: American Meteorological Society
Abstract: Components of the Simple Biosphere Model (SiB) of Sellers et al. were used to generate global monthly fields of surface albedo (0.4?4.0 ?m), roughness length and minimum surface (stomatal) resistance. SiB consists of three ...
A Simplified Biosphere Model for Global Climate Studies
Publisher: American Meteorological Society
Abstract: The Simple Biosphere Model (SiB) as described in Sellers et al. is a bio-physically based model of land surface-atmosphere interaction. For some general circulation model (GCM) climate studies, further simplifications are ...
Hemispherical Reflectance Variations of Vegetation Canopies and Implications for Global and Regional Energy Budget Studies
Publisher: American Meteorological Society
Abstract: The variations of spectral hemispherical reflectance (albedo) in vegetation canopies were studied as a function of solar zenith angle, leaf area index, led orientation distribution, and leaf and soil optical, properties. ...
A Review of Satellite Data Algorithms for Studies of the Land Surface
Publisher: American Meteorological Society
Abstract: Satellite observations are essential for the global monitoring of climatologically significant interactions between the earth's atmosphere and land surface. In practice, however, interpretation of remote-sensing data ...
A Simple Biosphere Model (SIB) for Use within General Circulation Models
Publisher: American Meteorological Society
Abstract: A simple but realistic biosphere model has been developed for calculating the transfer of energy, mass and momentum between the atmosphere and the vegetated surface of the earth. The model is designed for use in atmospheric ...
Modeling of Energy, Water, and CO2 Flux in a Temperate Grassland Ecosystem with SiB2: May–October 1987
Publisher: American Meteorological Society
Abstract: The Simple Biosphere Model, version 2 (SiB2), was designed for use within atmospheric general circulation models as a soil?vegetation?atmosphere transfer scheme that includes CO2 flux prediction. A stand-alone version of ...
Sensitivity of Climate to Changes in NDVI
Publisher: American Meteorological Society
Abstract: The sensitivity of global and regional climate to changes in vegetation density is investigated using a coupled biosphere?atmosphere model. The magnitude of the vegetation changes and their spatial distribution are based ...
