The Eddy Correlation Flux Measurement system provides in situ, 30 - minute measurements of the surface turbulent fluxes of momentum, sensible heat, latent heat, and carbon dioxide. (arm.gov)
The eddy correlation (ECOR) flux measurement system provides half - hour measurements of the surface turbulent fluxes of momentum, sensible heat, latent heat, and carbon dioxide. (arm.gov)
Over land, you have a surface energy balance that includes downwelling IR, upwelling IR (Stefan Boltzmann), downwelling solar radiation minus what is reflected back from the surface, latent heat flux and sensible heat flux (these are turbulent fluxes associated with exchange with the atmosphere), and conductive flux from the ground (below the surface).
