METAS Lab calibration workshop
METAS, with the support of STANBC partners and stakeholders, organized a successful calibration workshop at the METAS lab facilities (24/04-24/05/2024). The workshop focused on the comparison of filter-based absorption photometers using different aerosol mixtures to mimic fresh and aged soot particles under various environmental conditions. During the METAS campaign, a 1-day training workshop was held on April 25, 2024, for consortium members and stakeholders. This workshop focused on the generation of reference carbonaceous aerosols, with an emphasis on the use of the OCU oxidation flow reactor.
