% [T,XN,XS,EN,ES,SCALE]=CFC11ATMHIST05 Returns columnn vectors of:
% T     = Time (mid year)
% XN    = Mixing ratio in N. hemisphere [ppt]
% XS    = Mixing ratio in S. hemisphere [ppt]
% EN    = Uncertainty in N. hemisphere mixing ratio [ppt]
% ES    = Uncertainty in S. hemisphere mixing ratio [ppt]
% SCALE = Ascii name of calibration scale
%
% All concentrations are on the SIO-2005 calibration scale
%
% Atmospheric lifetime assumed to be  45.0 years
