The data tables in this file were used to generate the figures in the manuscript, "Summertime organic carbon absorption and sources at a southeastern U.S. location - dominance of secondary organic aerosol". Light-absorbing organic carbon, i.e. brown carbon, has been intensively investigated in atmospheres impacted by biomass burning impacted atmospheres. However, other brown carbon sources have been rarely studied in ambient aerosols. This data set includes forty-five PM2.5 filter samples that were collected in Research Triangle Park (RTP), NC, USA from June 1st to July 15th, 2013. The bulk carbonaceous components, including organic carbon, elemental carbon, water soluble organic carbon, and an array of organic molecular markers were measured; an ultraviolet (UV)/visible (Vis) spectrometer was used to measure the light absorption of methanol and water extractable organic carbon. A complete description of how the data was acquired and and analyzed is provided in the manuscript. A description of each parameter presented is provided in the file in the Data Dictionary.
