Estimates of Evapotranspiration with a One- and Two-Layer Model of Heat Transfer over Partial Canopy Cover
Publisher: American Meteorological Society
Abstract: One of the applications of remotely sensed surface temperature is to determine the latent heat flux (LE) or evapotranspiration (ET) from held to regional scales. A common approach has been to use surface-air temperature ...
Surface Water Vapor and Momentum Fluxes under Unstable Conditions from a Rugged-Complex Area
Publisher: American Meteorological Society
Abstract: Measurements were made of the profiles of mean wind velocity, of temperature, and of specific humidity in the unstable atmospheric boundary layer over macro-rough terrain; these data were obtained from radiosonde observations ...
Budgets of Water Vapor in the Unstable Boundary Layer over Rugged Terrain
Publisher: American Meteorological Society
Abstract: Inversion fluxes of water vapor are calculated for 11 clear days using profile data from a sequence of radio soundings over hilly terrain in the Pre-Alpine region of Switzerland. The relationships between the mixed layer ...
Evaporation and Humidity Profiles for Neutral Conditions over Rugged Hilly Terrain
Publisher: American Meteorological Society
Abstract: An analysis was made of vertical profiles of mean specific humidity in the hilly pre-Alpine region in Switzerland under conditions of new neutral atmospheric stability. The profile data were derived from radiosonde ...
Spatially Distributed Sensible Heat Flux over a Semiarid Watershed. Part II: Use of a Variable Resistance Approach with Radiometric Surface Temperatures
Publisher: American Meteorological Society
Abstract: Radiometric surface temperature images from aircraft observations over the Walnut Gulch Experimental Watershed, a semiarid rangeland watershed, were used with ground-based meteorological data at a reference site for ...
Estimating Spatial Variability in Atmospheric Properties over Remotely Sensed Land Surface Conditions
Publisher: American Meteorological Society
Abstract: This paper investigates the spatial relationships between surface fluxes and near-surface atmospheric properties (AP), and the potential errors in flux estimation due to homogeneous atmospheric inputs over heterogeneous ...
Impact of Using Different Time-Averaged Inputs for Estimating Sensible Heat Flux of Riparian Vegetation Using Radiometric Surface Temperature
Publisher: American Meteorological Society
Abstract: A riparian corridor along the Rio Grande dominated by the Eurasian tamarisk or salt cedar (Tamarix spp.) is being studied to determine water and energy exchange rates using eddy covariance instrumentation mounted on a 12-m ...
An Empirical Investigation of Convective Planetary Boundary Layer Evolution and Its Relationship with the Land Surface
Publisher: American Meteorological Society
Abstract: Relationships among convective planetary boundary layer (PBL) evolution and land surface properties are explored using data from the Atmospheric Radiation Measurement Program Cloud and Radiation Test Bed in the southern ...
The Soil Moisture–Atmosphere Coupling Experiment (SMACEX): Background, Hydrometeorological Conditions, and Preliminary Findings
Publisher: American Meteorological Society
Abstract: The Soil Moisture?Atmosphere Coupling Experiment (SMACEX) was conducted in conjunction with the Soil Moisture Experiment 2002 (SMEX02) during June and July 2002 near Ames, Iowa?a corn and soybean production region. The ...
