Transport processes regulating the lowermost stratospheric ozone reservoir (C05)

• Subject Area: Atmospheric Science
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 428312742

We will combine state-of-the-art reanalysis data (ERA-5, MERRA-2) and comprehensive measurements of ozone in the UTLS to determine the dynamical processes controlling the ozone budget in the UTLS. We will use the IAGOS-CARIBIC data set from 2004 until 2020 and which includes ozone in combination with transport relevant species. The combination of rea-nalysis data interpolated along the flight track with in-situ observations will allow us to disentangle different transport processes relevant for LMS ozone in different regions of the Northern Hemisphere. We will apply a tropopause referenced adiabatic coordinate framework allowing to account for the jet- and tropopause based variability.
