ERB is participating in, and supporting, several airborne field campaigns in 2022 and 2023 including SABRE
, and ACCLIP
. These projects are designed to improve understanding of the stratospheric aerosol layer, how particles formed from ocean emissions of gases affect the reflectivity of marine clouds, and how particles from different sources scatter and absorb sunlight. Measurements of aerosol extinction and absorption and of the number of aerosol particles as a function of their size, are vital to understanding all of these processes. These measurements are considered mission-critical for the planned field campaigns. This project provides continued airborne field campaign support for these measurements by hiring additional staff to improve and test instruments, install them on the research aircraft, participate in field measurements, and lead analysis, interpretation, and publication of the results.
