Multispectral BC Comparison to Continuous Mass Measurement of Wide-Ranging Aerosols

摘要

1. Linear relationship between BC(880), BC(370) and mass at low mass concentrations (＜100 g/m~3). 2. Roll off at higher concentrations 3. Results of linear regression indicate that BC(880) comprises～0.5% of total mass 4. Results of linear regression indicate that BC(370) is ～18% of total mass. 5. Smoke chamber results for BC(370) vs. BC(880) could indicate enhanced absorption or scattering. 6. Field test results are consistent with only BC present. 7. Low-modest correlation between mass and BC 8. Good comparison with collocated TAPI-633.
