NGeo2017_plots.m

The code in NGeo2017_plots.m will generate the plots in the main body of the paper Linz et al. 2017 "The strength of the meridional overturning circulation of the stratosphere". The N2O data set starts in late 2004 and is derived from the GOZCARDS data product and the Mauna Loa N2O time series. The tropical heights were determined using the MIPAS temperature and pressure. WACCM SF6 age is a shorter time series than WACCM ideal age because the earlier years were removed so as to avoid extrapolating the reference time series backwards in time. The ERA-I timeseries of overturning circulation strength is also included.
