7 South East Asian Studies / Biomass-burning, Aerosols, and Stratocumulus Environment: Lifecycles and Interactions Experiment

Date Range: 

Friday, February 1, 2013 to Sunday, April 19, 2015

7-SEAS/BASELInE focuses on addressing the following key questions: 1) What processes, interactions, and feedbacks control the lifecycle of biomass-burning aerosols from source to receptor regions in boreal spring Southeast Asia? 2) How do droplet nucleation and the resulting products (e.g., cloud albedo, water con-tent, precipitation efficiency, etc.) of warm rain processes in the cloud-resolving model simulations respond with respect to key aerosol physicochemical observables (e.g., number/mass concentration, size/shape distribution, and chemical composition) over a regional scale? 3) How do changes to aerosol-cloud interactions in boreal spring Southeast Asia provide feedbacks to regional climate through exchanges of energy, water, gases, and particulate matter between the surface and troposphere? 

7-SEAS/BASELInE deployment domain and distribution of supersites (red circles), satellite sites (blue circles), and AERONET sites (yellow circles) are shown below. Along the “river of smoke aerosols,” there are five supersites (near source regions at Doi Angkhang, Thailand; long-range transport at Son La, Vietnam; aerosol-cloud interactions at Yen Bai, Vietnam; near sink areas at sea-level of Hengchun, Taiwan and at free-troposphere of Lulin Atmospheric Background Station, LABS, Taiwan). Within the deployment domain, seven operational AERONET sites will provide continuous sunphotometry measurements and retrievals. Furthermore, eight AERONET sites equipped with additional remote sensing and/or in-situ instruments are classified as the satellite sites.
