Absorption and Scattering of Aerosol measured onboard R/V Gisang1 over the Yellow Sea
Abstract
Absorption and scattering coefficient were measured onboard RV Gisang 1 over the Yellow Sea (covering 124° 127°E, 31° 38°N) during May June, 2016. BC concentration was analyzed at seven wavelengths (370, 470, 520, 590, 660, 880, and 950nm) every 1 minute by Aethalometer. Scattering coefficient was measured at three wavelengths (450, 550, and 750nm) every 5 minutes with Nephelometer. The mean absorption coefficient was 1.2 Mm-1 at 880nm and the mean scattering coefficient was 116Mm-1 at 550nm. Single scattering albedo(SSA) reached the maximum value of 3.0 at 700nm. The calculated mean scattering angstrom exponent(SAE) was 1.6 and absorbing angstrom exponent(AAE) was 1.1. The AAE and SAE were higher in aged Chinese plume.
