RISSpatial Variability of Net Radiation and Soil Heat Flux Density on Two Logged Sites at Montmorency, Quebec
Publisher: American Meteorological Society
Abstract: Net radiation data from 32 sample points and soil heat flux density values from six sample points on two logged sites at Montmorency in 1979 are presented. The two sites were of different ages; one had been clearcut in ...
Evaluation of a Bowen Ratio Measurement System over Forest and Clear-Cut Sites at Petawawa, Ontario
Publisher: American Meteorological Society
Abstract: This paper reports on the features of a reversing measurement system for the determination of the Bowen ratio. Ten-junction thermopiles are used to measure wet- and dry-bulb temperature differences, and a single thermocouple ...
A Note on Temperature and Humidity Profile Measurement over Forests Using Diodes
Publisher: American Meteorological Society
Abstract: An instrument package developed for measuring six-level, dry-bulb and wet-bulb temperature profiles above forests is described. Germanium diodes, incorporated into a constant current circuit, were used as temperature ...
Comparative Performance of Two Reversing Bowen Ratio Measurement Systems
Publisher: American Meteorological Society
Abstract: This paper reports on the results of a comparative experiment between two Bowen ratio measurement systems conducted at the Petawawa National Forestry Institute, Chalk River, Ontario, in 1985. Both systems interchange the ...
Calculation of Area-Averaged Fluxes: Application to BOREAS
Publisher: American Meteorological Society
Abstract: This study estimates area-averaged fluxes over the Boreal Ecosystem?Atmosphere Study (BOREAS) region using tower and aircraft data. The dependence of the area-averaged flux on various assumptions and external flow ...
THORPEX Research and the Science of Prediction
Publisher: American Meteorological Society
Abstract: he Observing System Research and Predictability Experiment (THORPEX) was a 10-yr, international research program organized by the World Meteorological Organization?s World Weather Research Program. THORPEX was motivated ...
