The dataset includes composition-resolved size distributions the integrated mass of sulfate, organics, nitrate, sea salt, dust, black carbon, and other compounds in coarse and fine fractions; extinction and absorption coefficients from each species at both dry and ambient conditions; asymmetry parameters; Angstrom exponents; and fitted lognormal functions to describe the size distribution. Optical parameters are calculated for 10 wavelengths from the near UV to the near IR, and size distributions range from 3 nm to 50 um in diameter. One file contains these data at 1-minute time intervals. Another file contains a subset of these data averaged into 1 km vertical bins for each vertical profile the aircraft made, as well as composition-resolved integrated aerosol optical depth derived from each profile. The concentration of cloud condensation nuclei is calculated for 5 supersaturations}, publisher={ORNL Distributed Active Archive Center}, author={Brock, C.A. and Froyd, K.D. and Dollner, M. and Williamson, C.J. and Schill, G.P. and Murphy, D.M. and Wagner, N.L. and Kupc, A. and Jimenez, J.L. and Campuzano-Jost, P. and Nault, B.A. and Schroder, J.C. and Day, D.A. and Price, D.J. and Weinzierl, B.B. and Schwarz, J.P. and Katich, J.M. and Wang, S. and Zeng, L.H. and Weber, R. and Dibb, J.E. and Scheuer, E. and Diskin, G.S. and DiGangi, J.P. and Bui, T.P. and Dean-Day, J.M. and Thompson, C.R. and Peischl, J. and Ryerson, T.B. and Bourgeois, I. and Daube, B.C. and Commane, R. and Wofsy, S.C.}, year={2021}, language={en}, }
