TL;DR: In situ measurements of nitric acid (HNO 3 ), reactive nitrogen (NO y ), nitric oxide (NO), and ozone (O 3 ) made in the upper troposphere (UT) and lower stratosphere (LS) between 29° and 33°N latitudes during September 1999 are used to examine NO y partitioning and correlations between the measured species in these regions.
