Estimating sensible and latent heat fluxes over rice using surface renewal

Castellvi, F.; Martinez-Cob, A.; Perez-Coveta, O.

The performance of surface renewal (SR) analysis for estimating sensible (H) and latent (lambda E) heat fluxes has been analysed over a sprinkler irrigated rice. Similarity principles were not fully met during the experiment and the (H + lambda E) measured values with the eddy covariance did not close the surface energy balance. H and lambda E estimates using SR analysis were reliable and provided a reasonable energy-balance closure. The Bowen ratio was also estimated using SR analysis. Good estimates were obtained though mainly under unstable atmospheric conditions.
