Uncertainty Due to Hygrometer Sensor in Eddy 1 Covariance Latent Heat Flux Measurements
9 Half-hour latent heat flux (LE) was measured over an early-maturing peach orchard 10 (Prunus persica L.) by two different hygrometers: 1) infrared gas analyzer (IRGA) (Li11 COR, model Li-7500); and 2) ultraviolet hygrometer (Campbell, KH20). A good 12 agreement between LE obtained with the IRGA (LEIRGA) and the KH20 (LEKH20) 13 hygrometers was observed. During rainy periods, LEIRGA and LEKH20...
متن کاملBayesian multimodel estimation of global terrestrial latent heat flux from eddy covariance, meteorological, and satellite observations
Accurate estimation of the satellite-based global terrestrial latent heat flux (LE) at high spatial and temporal scales remains a major challenge. In this study, we introduce a Bayesian model averaging (BMA) method to improve satellite-based global terrestrial LE estimation by merging five process-based algorithms. These are the Moderate Resolution Imaging Spectroradiometer (MODIS) LE product a...

متن کاملAn Empirical Orthogonal Function-Based Algorithm for Estimating Terrestrial Latent Heat Flux from Eddy Covariance, Meteorological and Satellite Observations
Accurate estimation of latent heat flux (LE) based on remote sensing data is critical in characterizing terrestrial ecosystems and modeling land surface processes. Many LE products were released during the past few decades, but their quality might not meet the requirements in terms of data consistency and estimation accuracy. Merging multiple algorithms could be an effective way to improve the ...
متن کاملAssessment of Spatial Representativeness of Eddy Covariance Flux Data from Flux Tower to Regional Grid
Combining flux tower measurements with remote sensing or land surface models is generally regarded as an efficient method to scale up flux data from site to region. However, due to the heterogeneous nature of the vegetated land surface, the changing flux source areas and the mismatching between ground source areas and remote sensing grids, direct use of in-situ flux measurements can lead to maj...
