ASSOCIATED_DATA: N/A
INSTRUMENT_INFO: WPI LWCC and Ocean Optics USB4000 spectrometer
DATA_INFO: Filters were first extracted in 15 ml of water, dried and then extracted again using 15 ml of methanol. Each extract was filtered with a 0.45 um pore size syringe filter and then injected through a 2.5 m path length LWCC and light absorption measured by Ocean Optics USB4000 spectrometer. Absorption from 300 to 700 nm were recorded. Absorption of pure solvent was subtracted from the sample. Raw absorption data were processed by the equation Abs=Raw*(Volume of extraction liquid)/(Volume of air collected at STP)/(Optical Path Length, 2.5m here)*ln(10). Brown carbon absorption was determined by absorption at 365 nm. Data reported here were averaged over 20 nm wavelength intervals. i.e. absorption at 400 nm were average by absorption data between 390 nm to 410 nm. Absorption data have been blank corrected by averaging all blank filter in this mission (2-3 blank filters per flight). Limit of detection (LOD) was determined by three times standard deviation of blank data. STP is T=273K & p=1013 mb).
