Bounding the role of aerosols on the Arctic climate with in situ observations

During this year’s ASSW meeting in Fairbanks, Alaska, the air Pollution in the Arctic: Climate, Environment and Societies(PACES) project will hold a meeting entitled “Arctic air pollution: A collaborative framework for natural and social science”.

The IASOA working group on Aerosols has summarized the Arctic black carbon science questions...

The Atmospheric Working Group of the International Arctic Science Committee (IASC) and the IGBP core project International Global Atmospheric Chemistry (IGAC) are co-sponosoring a workshop this spring on Future Directions for Arctic Air Pollution Research.  Invitees will represent research conducted at the long-term Arctic surface sites, Arctic field campaigns, and the modeling community.  


IASOA black carbon experts contributed to the 2013 Arctic Report Card.

Most IASOA observatories are measuring aerosols. Some instruments, like the aethalometer, specifically target equivalent black carbon.

This presentation was given at the first IASOA Equivalent Black Carbon workshop in Vancouver, CA. It presents proposed steps forward for utilizing the historical records of aethalometer data to begin to bound the impact of Arctic Black Carbon.

Seven IASOA observatories (Alert, Barrow, Pallas, Summit, Tiksi, Station Nord and Ny-Ålesund) monitor aerosol optical properties including concentrations of absorbing equivalent black carbon.  Despite the unique and exciting analysis opportunities afforded to scientists by an Arctic-wide EBC measurement network, comparing data across stations requires caution because diverse filter-based instruments have been deployed.

This study examined the information preferences of a range of Arctic Black Carbon information stakeholders.

The IASOA Black Carbon working group is closely coordinated with the Global Atmosphere Watch (GAW) Aerosol program.
