CIRPAS Twin Otter Aerosol Particle Soot Photometer Data

Airborne measurements of particle light absorption coefficient were measured using the Twin Otter aircraft during ACE-Asia. Measurements were made using a Particle Soot Absorption Photometer (Radiance Research, Seattle WA) located onboard a modified De Havillan DHC-6 Twin Otter aircraft operated by the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS). A total of 19 Research Flights were conducted between March 31 and May 1, 2001. The files are in .txt format.
