e6193 Aug 2004 redo 619 with fixed 1979 source gases. (b55_50yr winds) The same as e619 except the source gases are fixed to 1979 levels.

- running
e6194 Sept 2005 redo 619 with fixed 1960 source gases. (b55_50yr winds) Implemented as e619 except the source gases are fixed to 1960 values. Initial restart file used was experiment 619 19730201 and all chlorine fields were adjusted to 1960 values, except for ch3cl which was untouched. Two year spin up using 1977, 1978 met fields to allow chlorine values to reach equilbrium.

e6195 Feb 2007 redo 619 with an initial pulse of f11 in all gridboxes (1.8e-10 extra) and thereafter holding the surface level of f11 constant For purposes of studying Alpha

e6196 Feb 2007 redo 619 with an initial pulse of h12_24 (halon 1211 and halon 2402) in all gridboxes (8e-12 extra) and thereafter holding the surface level of h12_24 constant For purposes of studying Alpha

e719 25 Jan 2008 rerun 20 years of 619 on the NCCS Linux Networx Cluster (discover) see details of e619

e720 6 Mar 2008 same as e719, except that polar chemistry was disabled Zeroed out heterogeneous rate coefficients for: ClONO2+H2O, ClONO2+HCl, N2O5+HCl, HOCl+HCl, BrONO2+H2O (N2O5+H2O rate was preserved). For all other details see e619.
