Field testing two flux footprint models

چکیده

Abstract. A field study was undertaken to investigate the accuracy of two micrometeorological flux footprint models for calculating gas emission rate from a synthetic 10 × m surface area source, based on vertical measured at fetches 15 50 downwind source. Calculations were made with an easy-to-use tool Kormann–Meixner analytical model and more sophisticated Lagrangian stochastic dispersion model. total 59 testable min observation periods over 9 d. On average, both underestimated actual release by approximately 30 %, mostly due large underestimates larger fetches. The calculations had period-to-period variability, no statistical differences observed between in terms overall accuracy.

Experimental Evaluation of Analytical and Lagrangian Surface-layer Flux Footprint Models

Three surface-layer flux footprint models have been evaluated with the results of an SF6 tracer release experiment specifically designed to test such models. They are a Lagrangian stochastic model, an analytical model, and a simplified derivative of the analytical model. Vertical SF6 fluxes were measured by eddy correlation at four distances downwind of a near-surface crosswind line source in a...

Comparing two testing procedures in unbalanced two-way ANOVA models under heteroscedasticity‎: Approximate degree of freedom and parametric bootstrap approach

‎The classic F-test is usually used for testing the effects of factors in homoscedastic two-way ANOVA models‎. ‎However‎, ‎the assumption of equal cell variances is usually violated in practice‎. ‎In recent years‎, ‎several test procedures have been proposed for testing the effects of factors‎. ‎In this paper‎, ‎the two methods that are approximate degree of freedom (ADF) and parametric bootstr...
