Measuring Ecosystem Responses To Water Availability: How Dry Is Too Dry To Hinder Evapotranspiration?

Drought is one of the most devastating natural disasters that can cause serious agricultural, economic, and social impacts around the globe. Several studies project increased aridity over land and more widespread droughts associated with the changing climate, which could have profound impacts on agriculture, ecosystem service, and human welfare. Yet, most of the existing drought monitoring indices are based on drought stress derived from environmental conditions rather than actual ecosystem responses, neglecting potential feedbacks between biosphere and atmosphere. However, studies...

Surface Layer Energy And Carbon Fluxes Are Vulnerable To The Representation Of Canopy Structural And Functional Profiles

The terrestrial carbon uptake currently accounts for about one-third of the annual global carbon sink in the atmosphere; however, future projections of the terrestrial carbon cycle is uncertain due to the complex, nonlinear interactions in the earth's climate system. Studies have shown that carbon sequestration strength varies with different ecosystems, and its magnitude is greatly regulated by the amount of photosynthetic leaves inside plant canopies. Although various ecophysiological treatments have been applied in different land surface models, the amount of...
