# ** species-directory take hyphens instead of underscores previously;
# ** likewise for species names within filenames;
# ** variable names stay with underscores.

#--v3 of my script to extract global mean and put to IGCM format

#--according to Malte Meinsheausen two options are possible 
#    CFC11=CFC11eq and CCFC12=CFC12
# or CFC11=HFC134a-eq * (0.0100/62.7)/(0.062/238) [values from AR5] and CFC12=CFC12eq 
# in the second case the HFC134a-eq is converted into CFC11eq using RF efficiencies from AR5 in Wm-2pptv-1 

#--11/10/2016 New format for the data, now global, NH and SH means are in a sector dimension
#--hence I parse the first value from the cdo outputf to get the global mean
#--outputf is used with format %12.4e to make sure there is a space between values and 3 values per line

#--dir for annual mean data
