CAFE-Brazil

Chemistry of the Atmosphere - Field Experiment in Brazil

Dec. 2022 - Jan. 2023

CAFE-Brazil was a HALO mission conducted out of Manaus, Brazil. It focused on tropospheric oxidant photochemistry in combination with particle formation and growth mechanisms under clean, pristine conditions over the Amazon rainforest.

It was funded by the Max Planck Society and the DFG (HALO-SPP 1294).
