Title

Nitrous oxide fluxes from an intensively managed grazed grassland in Scotland

Abstract

This data set contains terrestrial fluxes of N2O from an intensively managed grazed grassland in Scotland measured using eddy covariance and chamber methods . The effect of a tillage event and two nitrogen fertilizer applications were investigated by comparing N2O fluxes from two adjacent intensively managed grazed grasslands , one of which was tilled. An eddy covariance system mounted at 2.4 m was used to measure fluxes of N2O, H2O and CO2 using a quantum cascade laser (QCL) gas analyser. Flux measurements were made over a six month period starting at the end of March, 2012. Chamber measurements were also made using both static and dynamic chambers. The data was collected as part of the GHG Platform project AC0116 funded by DEFRA. Full details about this dataset can be found at https://doi.org/10.5285/7f54018c-3071-4213-8cee-78f8bd57977d

Lineage

Eddy covariance raw data from the QCL and sonic anemometer was recorded in tandem using a Labview program. This data was then processed using the Eddypro software version 5.2.1. The data was filtered through a quality control system as described in Cowan, N. J., Levy, P. E., Famulari, D., Anderson, M., Drewer, J., Carozzi, M., Reay, D. S., and Skiba, U. M.: The influence of tillage on N~2~O fluxes from an intensively managed grazed grassland in Scotland, Biogeosciences, 13, 4811-4821, https://doi.org/10.5194/bg-13-4811-2016, 2016. Raw concentration data for the chamber methods was processed to calculate fluxes. These fluxes were calculated using the HMR package in the statistical environment R. Met data from the Easter Bush site was collected in 2012 by various methods and quality control was carried out by comparison with nearby met stations.
