COALA (Characterizing Organics and Aerosol Loading over Australia) is a broad project designed to study the emissions and atmospheric chemistry of Australian biogenic species in pristine conditions and as they interact with anthropogenic pollution. Recent technological developments now make it possible to study in unprecedented detail the reactive carbon budget for isoprene, monoterpenes and sesquiterpenes, including quantifying emissions, transformations and deposition. These new developments will allow us to address specific questions related to a major uncertainty associated with climate forcing: knowing how emissions were processed in a pristine environment representative of pre-industrial conditions. The isolated urban areas of Australia, located close to pristine forests, will also allow us to quantify the impact of isoprene, monoterpenes and sesquiterpenes on urban air quality, and to address questions associated with the emerging science of lower NOx regimes in the mature industrialized world of the Northern Hemisphere.

COALA is an international collaboration bringing together resources and facilities from Australia (multiple funding sources), US (NSF), and the UK (NERC). COALA is the “umbrella” for three main projects:
JOEYS: Joint Organic Emissions Year-round Study (primarily Australian funding)
BAIR: Biogenic Anthropogenic Interactions Research (primarily US NSF funding)
TALENT: Testing Analogues for the Low Emission of NOx Transition (primarily UK NERC funding)
Each project is designed as a standalone effort with specific addressable science questions but each will be greatly enhanced by the complementary measurements of the other projects. COALA’s main purpose is to ensure that the objectives of the individual projects are coordinated. An intensive COALA field phase will be held in January-February 2020 focused on Sydney and the surrounding areas in southeastern Australia.

A white paper describing COALA is available. We welcome comments and suggestions on the white paper and invite community collaboration of the development of a proposal and facility request to NSF for the NCAR/EOL Integrated Surface Flux System, as well as ground-based chemistry measurements.  Please send comments to any member of the COALA Steering Group.

There is also opportunity to propose sampling from the Research Vessel Investigator.

A side meeting on COALA was held at the IGAC conference in Breckenridge Sep 29, 2016 (presentation slides).
