Evidence for winter/spring denitrification of the stratosphere in the nitrate record of Antarctic firn cores
A firn core from within the polar vortex in the Weddell Sea sector of Antarctica shows nitrate peaks that occur in the spring or early summer. They are far less prominent in two other cores from sites that are further north. Although other data are needed, circumstantial evidence suggests that the p...
