RISSimulation of Tracer Concentration Data in the Brush Creek Drainage Flow Using an Integrated Puff Model
Publisher: American Meteorological Society
Abstract: During the 1984 ASCOT field study in Brush Creek Valley, two perfluorocarbon tracers were released into the nocturnal drainage flow at two different heights. The resulting surface concentrations were sampled at 90 sites, ...
Pollutant Transport and Diffusion in Katabatic Flows
Publisher: American Meteorological Society
Abstract: The characteristics of pollutant transport and diffusion of a passive contaminant in a two-dimensional katabatic flow over a simple slope are examined using a primitive equation hydrodynamic model. It is shown that pollutants ...
Mass and Momentum Balance in the Brush Creek Drainage Flow Determined from Single-Profile Data
Publisher: American Meteorological Society
Abstract: Fluxes and flux-divergences of mass and momentum in Brush Creek Valley, computed from measurements taken by Tethersondes and Doppler sodars in the 1984 ASCOT experiment, are presented. Estimates of mass influx from open ...
A Comparison of a Hierarchy of Models for Determining Energy Balance Components over Vegetation Canopies
Publisher: American Meteorological Society
Abstract: Several methods for estimating surface energy balance components over a vegetated surface are compared. These include Penman-Monteith, Deardorff, and multilayer canopy (CANWHT) models for evaporation. Measurements taken ...
