Estimation of the Latent Heat Flux over Irrigated Short Fescue Grass for Different Fetches

Often in agrometeorology the instrumentation required to estimate turbulent surface fluxes must be installed at sites where fetch is not sufficient for a sector of wind directions. For different integrated flux-footprints (IFFP) thresholds and taking as reference half-hourly latent heat (LE) measured with large weighing lysimeter (LELys), eddy covariance (EC) method two methods based on renewal (SR) analysis LE were tested over short fescue grass. One combined SR flux-gradient (profile) relationship, SR-P method, other dissipation SR-D method. When was estimated using traces air moisture, good performances obtained EC samples IFFP higher than 85%. However, closest estimates residual 50%, sensible flux determined performed close LELys accumulated LELys. To flux, can recommended day-to-day use by farmers because it friendly affordable.
