Abstract
A major marine cloud brightening campaign was planned to take place during Mid-February to early April 2023, described fully in this session by the presentation of the project’s Chief Scientist, Daniel Harrison. A central element of the campaign is spraying fine sea spray aerosols for enhancing CCN concentrations, and measuring the effects on marine boundary layer clouds with a cloud physics aircraft. This presentation will focus on observational evidence that the hypothesis that shipborne generated fine sea spray aerosols produce larger number of smaller cloud droplets that reflect more solar radiation will be tested along with the magnitude of this effect. In addition, the cloud effects of coarser sea spray aerosols optimized at maximizing the direct radiative effects will have been tested and will be reported. Satellite microphysical retrievals of the February 2022 campaign, which had no within cloud aircraft measurements, show already tantalizing indications in support of the hypothesis. Satellite retrievals of the seeding effects in the 2023 campaign will complement the aircraft measurements on the seeding effects, are presented in this session by Guy Pulik.
