Actual evapotranspiration (ET) is a major water use flux in a basin water balance with crucial significance for water resources management and planning. Mapping ET with good accuracy has been the subject of ongoing research. Such mapping is even more challenging in heterogeneous and data-scarce regions. The main objective of our research is to estimate ET using daily Moderate Resolution Imaging...
We propose a long-term parameterization scheme for two critical parameters, zero-plane displacement height (d) and aerodynamic roughness length (z0m), that we further use in the Surface Energy Balance System (SEBS). A sensitivity analysis of SEBS indicated that these two parameters largely impact the estimated sensible heat and latent heat fluxes. First, we calibrated regression relationships b...
• Five process-based ET models were integrated based on Gaussian process regression. regression was better than the other five machine learning methods. Integrated estimates more accurate currently available eight products. China terrestrial with a spatial and temporal resolution of 1 km 10 days is generated. Estimating evapotranspiration (ET) accurately at various scales crucial for understand...
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 ...
Evapotranspiration (ET) connects the land to atmosphere, linking water, energy, and carbon cycles. ET is an essential climate variable with a fundamental importance, accurate assessments of spatiotemporal trends variability in are needed from regional continental scales. This study compared eight global actual datasets (ETgl) average ensemble (ETens) based on remote sensing, reanalysis, land-su...
In 2015, an emergency state was declared in Bolivia when Poopó Lake dried up. Climate variability and the increasing need for water are potential factors responsible for this situation. Because field data are missing over the region, no statements are possible about the influence of mentioned factors. This study is a preliminary step toward the understanding of Poopó Lake drought using remote s...
