I'm using the "GEIA ocea" N2O data formerly available via http://geiacenter.org/presentData/n2o.html as part of an ensemble of gridded EIs (GEIs) providing input to a simulation of atmospheric N2O over North America. Fortunately, I have the data saved locally. I would prefer also to provide a valid source URI (or other identifier) for the data as part of the documentation for my project.
