Short summary
We report an efficient method to collect atmospheric NO2 adapted for multi-isotopic analysis and present the first NO2 triple oxygen and double nitrogen isotope measurements. Atmospheric samplings carried out in Grenoble, France, highlight the NO2 isotopic signature sensitivity to the local NOx emissions and chemical regimes. These preliminary results are very promising for using the combination of Δ17O and δ15N of NO2 as a probe of the atmospheric NOx emissions and chemistry.
