Oxygen Sensitivity of Krypton and Lyman-α Hygrometers
Publisher: American Meteorological Society
Abstract: The oxygen sensitivity of krypton and Lyman-α hygrometers is studied. Using a dewpoint generator and a controlled nitrogen/oxygen flow the extinction coefficients of five hygrometers associated with the third-order Taylor ...
Predicting Regional Transpiration at Elevated Atmospheric CO2: Influence of the PBL–Vegetation Interaction
Publisher: American Meteorological Society
Abstract: A coupled planetary boundary layer (PBL)?vegetation model is used to study the influence of the PBL?vegetation interaction and the ambient CO2 concentration on surface resistance rs and regional transpiration ?E. Vegetation ...
Scintillometer-Based Estimates of Sensible Heat Flux Using Lidar-Derived Surface Roughness
Publisher: American Meteorological Society
Abstract: he estimation of sensible heat flux, H, using large aperture scintillometer (LAS) under varying surface heterogeneity conditions was investigated. Surface roughness features characterized by variable topography and vegetation ...
