Potential evaporation at eddy-covariance sites across the globe [PDF]

Hydrology and Earth System Sciences, 2019
Potential evaporation (Ep) is a crucial variable for hydrological forecasting and drought monitoring. However, multiple interpretations of Ep exist, which reflect a diverse range of methods to calculate it.

ICOS eddy covariance flux-station site setup: a review

International Agrophysics, 2018
Abstract The Integrated Carbon Observation System Research Infrastructure aims to provide long-term, continuous observations of sources and sinks of greenhouse gases such as carbon dioxide, methane, nitrous oxide, and water vapour. At ICOS ecosystem stations, the principal technique for measurements of ecosystem-atmosphere exchange of GHGs is the eddy ...

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 ...

Towards a standardized processing of Net Ecosystem Exchange measured with eddy covariance technique: algorithms and uncertainty estimation [PDF]

Biogeosciences, 2006
Eddy covariance technique to measure CO2, water and energy fluxes between biosphere and atmosphere is widely spread and used in various regional networks. Currently more than 250 eddy covariance sites are active around the world measuring carbon exchange

Quantifying snow sublimation by Eddy covariance measurements on the High Atlas Mountain of Marrakech at Tazaghart plateau, Morocco [PDF]

Proceedings of the International Association of Hydrological Sciences
The High Atlas Mountains are a valuable source of water supply to lowland areas, in the Tensift watershed around Marrakech and play an important role in the hydrologic processes and water balance.

Urban Eddy Covariance – The INFLUX Network

Abstract. The eddy covariance method is used by various disciplines to measure surface-atmosphere fluxes of both vector and scalar quantities. However, eddy covariance observations are uncommon in urban areas. One of the few long-term and ongoing urban flux experiments is the Indianapolis Flux Experiment (INFLUX), which has successfully deployed eddy ...

Modeling Carbon and Water Fluxes of Managed Grasslands: Comparing Flux Variability and Net Carbon Budgets between Grazed and Mowed Systems

Agronomy, 2019
The CenW ecosystem model simulates carbon, water, and nitrogen cycles following ecophysiological processes and management practices on a daily basis. We tested and evaluated the model using five years eddy covariance measurements from two adjacent but ...

The Importance of Snow Sublimation on a Himalayan Glacier

Frontiers in Earth Science, 2018
Snow sublimation is a loss of water from the snowpack to the atmosphere. So far, snow sublimation has remained unquantified in the Himalaya, prohibiting a full understanding of the water balance and glacier mass balance. Hence, we measured surface latent

The characteristic of fractional uncertainty on eddy covariance measurement

Journal of Agricultural Meteorology, 2011
Micrometeorological heat, water, and CO2 fluxes have been widely monitored with the eddy covariance (EC) method. Its uncertainty information should be as important as the flux measurement itself and is indispensable to studies addressing site intercomparison, model validation, and model-data synthesis. Therefore, we estimated the fractional uncertainty

Impacts of Different Averaging Intervals on CO₂ Flux Calculation in a Moso Bamboo Forest

Atmosphere
The eddy covariance technique has become one of the most popular methods for measuring CO2 exchange between ecosystems and the atmosphere. Flux averaging intervals typically range from 15 to 60 min, with 30 min being the most commonly adopted setting ...
