Abstract:

Processed 10-minute surface sensible and latent heat flux measured at 215 cm above snow surface. The three eddy-covariance systems are a Campbell Scientific CSAT3 and a Krypton Hygrometer KH20, a Campbell Scientific IRGASON and a Campbell Scientific CSAT3 and a Li-COR Li-7500. The eddy-covariance systems were set up approximately 6m apart and directed into the mean wind. The processing software was TK3 from the University of Bayreuth. The timestamps indicate the middle of the 10-minute averaging period. Average variables, (co)variances, friction velocity and Monin-Obukhov stability parameter estimates are provided for convenience.
