A Regional Land Use Drought Index for Florida

open access: yesRemote Sensing, 2015
Drought index is a useful tool to assess and respond to drought. However, current drought indices could not fully reveal land use effects and they have limitations in applications.

Validating Evapotranspiraiton Equations Using Bowen Ratio in New Brunswick, Maritime, Canada

open access: yesSensors, 2008
Three methods including the Penman-Monteith (PM), Priestley-Taylor (PT), and 1963 Penman equation (PE) for calculating daily reference evapotranspiration (ETo) were evaluated in the Maritime region of Canada with the data collected from 2004 to 2007.

Emergent constraints on the hydrological impacts of land use and land cover change

open access: yesNature Communications
Land use and land cover changes have substantial effects on the terrestrial water cycle, but their sign and magnitude remain elusive at large scales. State-of-the-art Earth system models disagree on how these changes affect terrestrial evapotranspiration.

Future exposure to moist heat extremes linked to soil dryness

open access: yesnpj Climate and Atmospheric Science
Soil moisture critically modulates moist heat via surface energy fluxes, impacting human health and ecosystems under climate change. Using CMIP6 models with or without interactive soil moisture, we dissect its global role.

A semi-empirical model of the energy balance closure in the surface layer.

open access: yesPLoS ONE, 2018
It has been hypothesized that the energy balance closure problem of single-tower eddy-covariance measurements is linked to large-scale turbulent transport. In order to shed light on this problem, we investigate the functional dependence of the normalized

PULSE: A Novel Potential Underlying Water Use Efficiency‐Based Method for Latent Heat and Surface Energy Imbalance Correction

open access: yesWater Resources Research
Evapotranspiration (ET) plays a critical role in water and energy budgets over the land surface. Eddy Covariance (EC) is the most widely used technique to measure ET at ecosystem scale, providing insights into land–atmosphere interactions and serving as ...

A Novel Framework for Estimating the Bowen Ratio Over Small Water Bodies

open access: yesHydrological Processes
ABSTRACTThe Bowen ratio, defined as the ratio of sensible to latent heat flux, is crucial for quantifying land‐atmosphere energy exchanges and evaporation rates from terrestrial surfaces. Despite extensive research on the Bowen ratio over placid water surfaces (e.g., lakes), further investigation is needed to understand its dynamics in small reservoirs
