The net ecosystem exchange (NEE) is the difference between ecosystem CO 2 assimilation
and CO 2 losses to the atmosphere. Ecosystem respiration (R eco), the efflux of CO 2 from …

Evaporation from wet canopies (E) can return up to half of incident rainfall back into the
atmosphere and is a major cause of the difference in water use between forests and short …

Terrestrial photosynthesis is the largest and one of the most uncertain fluxes in the global
carbon cycle. We find that near‐infrared reflectance of vegetation (NIRV), a remotely sensed …

Several global gross primary production (GPP) and evapotranspiration (ET) remote sensing
products exist, mainly provided by machine-learning (eg MPI-BGC) and semi-empirical (eg …

Increasing vapor pressure deficit (VPD) increases atmospheric demand for water. While
increased evapotranspiration (ET) in response to increased atmospheric demand seems …

This paper outlines a new strategy to derive evaporation from satellite observations. The
approach uses a variety of satellite-sensor products to estimate daily evaporation at a global …

The energy balance at most surface-atmosphere flux research sites remains unclosed. The
mechanisms underlying the discrepancy between measured energy inputs and outputs …

The measured net ecosystem exchange (NEE) of CO2 between the ecosystem and the
atmosphere reflects the balance between gross CO2 assimilation [gross primary production …

Terrestrial photosynthesis is the basis for vegetation growth and drives the land carbon
cycle. Accurately simulating gross primary production (GPP, ecosystem-level apparent …

Terrestrial gross primary productivity (GPP) varies greatly over time and space. A better
understanding of this variability is necessary for more accurate predictions of the future …
