Abstract
The Southwest Monsoon is an important synoptic scale forcing that modulates precipitation and air quality throughout Southeast Asia. Diverse aerosol sources exist throughout the region. Understanding interactions between these particles and clouds is important for future climate predictions and societal response to more frequent periods of extreme flood and drought. Here we present airborne observations made in support of the NASA CAMP2Ex (Cloud and Aerosol Monsoonal Processes-Philippines Experiment) mission aboard the Wallops Flight Facility P-3 research aircraft, based at Clark International Airport in the Luzon region of Northern Philippines. Nineteen research flights were conducted in August-October of 2019.
An extensive suite of aerosol microphysical, optical, and chemical instrumentation was deployed, along with trace gas and remote sensing measurements, to characterize aerosol emissions and their vertical/spatial variability associated with moderately convective marine cloud systems in the region. Analysis will focus on the evolution of aerosols from Indonesian agricultural biomass burning activities, compared with urban emissions from the megacity Manila and transported air masses from mainland Asia. Dry mass scattering and absorption efficiencies are derived to assess optical treatments by global circulation models in this complex meteorological environment.
