...) is operationally providing forecast and reanalysis products of air quality and atmospheric composition. In this article, we present an extended evaluation of the CAMS global reanalysis data set of four reactive gases, namely, ozone (O 3 ), carbon monoxide (CO), nitrogen dioxide (NO 2 ), and formaldehyde (HCHO...

... present a characterization of reactive gases (RG: O 3 , NO, NO 2 ,SO 2 , CO) and methane (CH 4 ) variability in the central Mediterranean basin,analyzing in situ measurements at three new permanent WMO/GAW Observatories in Southern Italy: Capo Granitola – CGR (Sicily), Lamezia Terme – LMT (Calabria...

...; Christoph Zellweger; Michael E. Chang; Frank Flocke Long-term observations of reactive gases in the troposphere are important for understanding trace gas cycles and the oxidation capacity of the atmosphere, assessing impacts of emission changes, verifying numerical model simulations, and quantifying...
