Convective transport of tropospheric trace gases, aerosols, cloud particles and precursors of these in the tropics can extend into the lowermost stratosphere during deep convective events. Examples of these include tropical cyclones and mesoscale convective systems over water, and invigorated convection over land. Once transported into the stratosphere, particles and many trace gases have relatively long lifetimes. Many global-scale models do not represent disequilibrium, intermittent deep convective events accurately, and therefore underestimate their impact on lower stratospheric composition. In situ observations to examine transport across the tropopause are difficult or impossible to obtain in the tropical UT/LS, particularly in active deep convective systems. Instead we present evidence that we can use high-resolution space-based Radar/Lidar observations combined with model-level ERA5 reanalysis data to better characterize transport of tropospheric chemicals and aerosols to the lower stratosphere in the tropics during deep convective events.
