About Heat, Vapor, and Carbon-Dioxide Flux
By finding the covariance between the vertical wind speed fluctuations with temperature against humidity and carbon dioxide fluctuations, the sensible and latent heat flux, as well as vapor and CO2 fluxes, can be found. Virtual sensible heat flux can be determined by finding the covariance between the sonically determined temperature and vertical wind speed fluctuations.
