Inorganic nitrogen over the Western North Atlantic Ocean
The concentrations of the reactive nitrogen species NO2, NOx(= NO + NO2), NOy (the sum of all compounds of nitrogen and oxygen with the exception of N2O), particulate NO3 −, and volatile NO3 − were measured from ship and aircraft platforms over the western North Atlantic Ocean as part of the GCE/CAS...
