Short summary

In this field study at Dome C, Antarctica, we investigated the effect of solar UV photolysis on the stable isotopes of nitrate in snow via comparison of two identical snow pits while exposing only one to solar UV. From the difference between the average isotopic fractionations calculated for each pit, we determined a purely photolytic nitrogen isotopic fractionation of -55.8‰, in good agreement with what has been recently determined in a laboratory study.
