GLORIA data for: Biomass burning pollution in the South Atlantic upper troposphere: GLORIA trace gas observations and evaluation of the CAMS model

We present high resolution measurements of pollutant trace gases in the South Atlantic Upper Troposphere and Lowermost Stratosphere (UTLS) from the Gimballed Limb Observer for Radiance Imaging of the Atmosphere (GLORIA) during the SouthTRAC (Transport and Composition in the Southern Hemisphere Upper Troposphere/Lower Stratosphere) campaign with bases in Oberpfaffenhofen, Germany, and Rio Grande, Argentina, on board the German High Altitude and Long range research Aircraft (HALO), 2019.

Measurements of peroxyacetyl nitrate (PAN), ethane (C$_2$H$_6$), formic acid (HCOOH), methanol (CH$_3$OH), and ethylene(C$_2$H$_4$) show strong local enhancements up to altitudes of 14 km. More than 1000 pptv of PAN, more than 1400 pptv of C$_2$H$_6$, more than 600 pptv of HCOOH, more than 4000 pptv of CH$_3$OH, and more than 200 pptv of C$_2$H$_4$ are observed.
