Carbonyl sulfide fluxes and concentrations from midwestern US (Bondville, FermiLab and Chicago)

This data package includes measurements of carbonyl sulfide (OCS) fluxes and concentrations from flux towers in the midwestern US. The measurements were made at AmeriFlux towers and thus the data package also includes a subset of the standard eddy covariance and meteorological data (e.g. VPD and NEE) that are also available from the AmeriFlux portal. The measurements presented here were made to provide an independent constraint on whole ecosystem stomatal conductance from these ecosystems with the goal of testing how the relationship between gross primary production and stomatal conductance varies through the growing season. Furthermore, we derived whole canopy nighttime stomatal conductance estimates to test how stomatal conductance varies between native prairie and maize ecosystems. All data presented here were discussed in the publication "Seasonal evolution of canopy stomatal conductance for a prairie and maize field in the midwestern US from continuous carbonyl sulfide fluxes" in Geophysical Research Letters (doi: 10.1029/2019GL085652).
