Sonic Anemometer Calibrations, Michael Negale, David Cook

Michael Negale

Initial conditions and boundary conditions are important for climate and atmospheric modeling. In order to get correct initial and boundary conditions, correct measurements need to be made. The eddy correlation flux measurement system (ECOR) is one such system that measures fluxes in momentum, sensible heat, latent heat, and carbon dioxide (CO2). These fluxes are calculated using the eddy covariance technique, which involves wind components, air temperature, water vapor, and CO2 concentration. The ECOR uses a fast response three-dimensional wind sensor, sonic anemometer (SA), to measure wind components and speed of sound, which is used to derive the air temperature. The …
