Predicting evapotranspiration from drone-based thermography – a method comparison in a tropical oil palm plantation [PDF]

Biogeosciences, 2021
For the assessment of evapotranspiration, near-surface airborne thermography offers new opportunities for studies with high numbers of spatial replicates and in a fine spatial resolution.

Globally Scalable Approach to Estimate Net Ecosystem Exchange Based on Remote Sensing, Meteorological Data, and Direct Measurements of Eddy Covariance Sites

Remote Sensing, 2022
Despite a rapid development of Nature-Based Solutions (NBS) for carbon removal in recent years, the methods for evaluating NBS still have certain gaps. We propose an approach based on a combination of remote sensing data and meteorological variables to ...

Toward a consistency cross-check of eddy covariance flux–based and biometric estimates of ecosystem carbon balance [PDF]

, 2009
Quantification of an ecosystem's carbon balance and its components is pivotal for understanding both ecosystem functioning and global cycling. Several methods are being applied in parallel to estimate the different components of the CO2 balance. However,

The INFLUX network – eddy covariance in and around an urban environment [PDF]

Earth System Science Data
The eddy covariance method is used by various disciplines to measure atmospheric fluxes of both vector and scalar quantities. One long-term, multi-site urban flux network experiment was the Indianapolis Flux Experiment (INFLUX), which successfully ...

Eddy covariance fluxes over managed ecosystems extrapolated to field scales at fine spatial resolutions [PDF]

, 2023
o enable an evidence-based management of ecosystems to adapt to the climate crisis, we require fine spatiotemporal resolution estimates of carbon, water, and energy fluxes at the field scale.

Chemical sensor resolution requirements for near-surface measurements of turbulent fluxes [PDF]

Atmospheric Chemistry and Physics, 2011
Businger and Delany (1990) presented an approach to estimate the sensor resolution required to limit the contribution of the uncertainty in the chemical concentration measurement to uncertainty in the flux measurement to 10 % for eddy covariance ...

Comparison of different objective functions for parameterization of simple respiration models [PDF]

, 2008
The eddy covariance measurements of carbon dioxide fluxes collected around the world offer a rich source for detailed data analysis. Simple, aggregated models are attractive tools for gap filling, budget calculation, and upscaling in space and time.
