inGOS Project Flux Intercomparison Campaign
Easter Bush, Edinburgh (UK)
24 - 28 June 2013
The European Infrastructure Network InGOS (Integrated non-CO2 Greenhouse gas Observing System) aims to optimise and standardise flux measurement systems for non-CO2 greenhouse gases. To support this activity, the Centre for Ecology and Hydrology (CEH) in Edinburgh (UK) hosted a major intercomparison campaign for the measurement of micrometeorological fluxes of N2O on a managed grassland for the period 3rd to 28th June 2013.
Objectives: To verify a variety of N2O flux measurement setups using eddy covariance, REA or gradient method on the same field, for a duration of 4 weeks. All instruments were running in parallel for the first few days measuring background conditions, and continued for a three week period following the fertilisation event. All system has been calibrated together with the same gas standards. There was the opportunity to interface various analysers with a common anemometer / data acquisition system or to test independent complete systems against a reference. Data analysis will be performed individually with own methodology and in parallel following a common protocol.
Results: Daniela Famulari ( Land-Atmosphere exchange group, Centre for Ecology and Hydrology NERC) presented the results of a first analysis of the eddy covariance data sets at the ACCENT + Symposium in Urbino (Semptember 19th).
