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 NO_x 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 NO_x emissions and chemistry.
