Estimating sensible and latent heat fluxes over rice using surface renewal

Abstract The performance of surface renewal (SR) analysis for estimating sensible ( H ) and latent ( λE ) heat fluxes has been analysed over a sprinkler irrigated rice. Similarity principles were not fully met during the experiment and the ( H  +  λE ) measured values with the eddy covariance did not close the surface energy balance. H and λE 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.
