Aerosols

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

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

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.

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.
