Standardization of KoFlux Eddy-Covariance Data Processing [PDF]

Korean Journal of Agricultural and Forest Meteorology, 2009
The standardization of eddy-covariance data processing is essential for the analysis and synthesis of vast amount of data being accumulated through continuous observations in various flux measurement networks. End users eventually benefit from the open and transparent standardization protocol by clear understanding of final products such as ...

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 ...

Eddy covariance raw data processing for CO2 and energy fluxes calculation at ICOS ecosystem stations [PDF]

, 2019
open18siThe eddy covariance is a powerful technique to estimate the surface-Atmosphere exchange of different scalars at the ecosystem scale. The EC method is central to the ecosystem component of the Integrated Carbon Observation System, a monitoring ...

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 ...

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 ...

Scaling carbon fluxes from eddy covariance sites to globe: synthesis and evaluation of the FLUXCOM approach

Biogeosciences, 2019
. FLUXNET comprises globally distributed eddy-covariance-based estimates of carbon fluxes between the biosphere and the atmosphere. Since eddy covariance flux towers have a relatively small footprint and are distributed unevenly across the world ...

Energy balance closure for the LITFASS-2003 experiment [PDF]

, 2010
In the first part, this paper synthesises the main results from a series of previous studies on the closure of the local energy balance at low-vegetation sites during the LITFASS-2003 experiment.

Upscaling fluxes from towers to regions, continents and global scales using datadriven approaches [PDF]

, 2011
Quantifying the current carbon cycle of terrestrial ecosystems requires that we translate spatially sparse measurements into consistent, gridded flux estimates at the regional scale.
