Susquehanna Shale Hills Critical Zone Observatory (CZO) - Soil Surface N2O & CO2 Gas Flux Data for 2013, 2014, June 2016 (Pennsylvania, USA)
Soil surface N2O & CO2 (for 2013 & 2014) gas measured in situ using a Model 1412 Infrared Photoacoustic Spectroscopy (PAS) gas analyzer powered by a model EU1000i portable electric Honda generator. Soil surface N2O & CO2 (for June 2016) gas measured by collecting soil gas every 15 minutes for 1 hour into exetainer vials, returning the vials to the lab, and analyzing the sample gases on a gas chromatograph (GC). Flux determined by measuring gas concentration change over time based on the steady state chamber collar method. All gas flux sampling took place between 09:00 and 13:00 hours – the time of lowest diurnal temperature variability.
