Estimativa de fluxo de calor sensível com suporte de cintilometria – estudo de caso : Cidade Universitária - Ilha do Fundão/RJ
The large aperture scintillometer (CinLA) is an optical device used to estimate averaged sensible heat fluxes (H) from fluctuations in the refractive index of the turbulent atmosphere in a light beam spread between a transmitter and a receiver. The present dissertation proposes to study the …

Measuring Optical Turbulence Parameters With A Three-aperture Receiver
… to turbulence. Techniques used by two different scintillometers based on weak turbulence theory are discussed along with a method to estimate the inner scale developed by Hill. The theory and minimization algorithm used to infer the atmospheric parameters are discussed. The main focus is on the …

A multidisciplinary approach to reservoir characterization of the coastal Entrada erg-margin gas play, Utah
… panoramas of outcrops, measured sections, scintillometer measurements of field sections, facies analysis, 2D high-resolution shallow seismic surveys, porosity and permeability analysis, and sedimentary petrography. Logs from the North Hill Creek/Flat Rock gas field were analyzed and …

Understanding the Role of Vegetation Dynamics and Anthropogenic induced Changes on the Terrestrial Water Cycle
… eddy covariance and large aperture scintillometer observations. Our results indicated that the monthly precipitation and seasonal vegetation characteristics such as leaf area index, root length, and stomatal resistance are the main factors influencing ecosystem land surface energy …

Impact of time and spatial averages on the energy balance closure
… measured by an aircraft and a large aperture scintillometer (LAS). In this validation, the backward Lagrangian footprint model was used to estimate the source area of the measurement. It was found that both energy balance correction approaches did improve the agreement between time and spatial …
