Short summary

This study presents novel observations of the very short lived substances (VSLSs) bromoform, dibromomethane and methyl iodide with high-resolution meteorological measurements and Lagrangian transport in the Peruvian upwelling. With a simple source–loss estimate we identified VSLS abundances below the trade inversion to be significantly influenced by advection of regional sources, underscoring the importance of oceanic upwelling and trade winds on the atmospheric distribution of VSLS emission.
