A41E:
Multisensor, Model, and Measurement Synergy: Aerosol Sources and Their Environmental Effects I


Submit an Abstract to this Session


Session ID#: 58464

Session Description:
Aerosols perturb Earth’s radiation budget and hydrological cycles, impact climate air quality, and health. Changing land-cover, wildfire occurrence, agricultural practice, and fuel consumption, alter aerosol concentrations and composition.  In places, efforts aim at reducing aerosol loading; in others, loading is increasing due to drought, desertification, over-grazing, deforestation, and expanding industrialization.

Characterizing aerosol sources is a prerequisite for representing them in climate and air quality models.  Diverse measurement techniques have been applied for this purpose, along with methods that combine measurements and models. Yet, adequately prescribing aerosol source strength, injection height, and microphysical and chemical properties remains a forefront area of research.Additionally, spatial sampling mismatch between measurements and models creates discrepancies that require attention.

We welcome presentations discussing synergies among measurement techniques and/or models, that characterize aerosols and their environmental effects on regional-to-global scales. This year we are placing special focus on representing aerosol sources, past, present, and/or future.
