The reactivities were modeled by six global 3D atmospheric chemistry models (UCAR, GEOS-Chem, GISS-E2l, GMI, and UCI) and F0AM, a photochemical box model. The reactivities are based on the ATom-1 Modeling Data Stream (MDS) constructed from the 10-second merged ATom-1 observations with interpolation and fill values. The air parcels were constructed by each model with MDS initialization values for the core set of species that control the primary reactivity of the remote troposphere plus temperature and water vapor. Each model derived reactivities for five days (24 hrs) in August (1, 6, 11, 16, and 21) to sample different weather and cloud patterns over the month. For the 3D models, average reactivities and J-values of the five daily values and standard deviations are reported for each parcel. For F0AM, the box model, only a mean is given. Each model provides data for one representative year between 1997-2016. These respective profiles of modeled reactivity data streams (RDS) will provide critical information for validation of satellite data, particularly in remote areas where in situ data is lacking.}, publisher={ORNL Distributed Active Archive Center}, author={Flynn, C.M. and Prather, M.J. and Strode, S.A. and Steenrod, S.D. and Emmons, L. and Lacey, F. and Murray, L.T. and Wolfe, G.M. and Kim, M.J. and Crounse, J.D. and Diskin, G.S. and DiGangi, J.P. and Daube, B.C. and Commane, R. and McKain, K. and Ryerson, T.B. and Thompson, C.R. and Hanisco, T.F. and Blake, D.R. and Blake, N. and Apel, E. and Hornbrook, R.S. and Elkins, J.W. and Hintsa, E.J. and Moore, F.L. and Wofsy, S.C.}, year={2019}, language={en}, }
