Spring-summer atmospheric circulation and boundary layer processes modulating aerosol and cloud characteristics over the coastal Northeast Pacific during EPCAPE

Abstract. Observations from the ARM Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE) spanning April to October 2023 at Scripps Pier, La Jolla, California (32.8663° N, 117.2546° W) were used to investigate the regional-scale atmospheric factors that control the vari...

Observations show increased nitrate in coastal cloud droplet residuals from large-particle activation and N 2 O 5 hydrolysis

Clouds change the chemical composition of aerosols, yet observations characterizing these processes are quite limited. Ground-based in-cloud measurements in coastal Southern California show that the highest nitrate to sulfate ratio (2.5 ± 1.7) in droplet residuals is near cloud b...
