The file "contr_global.nc" shows you the basic simulation. The rest is named as in your slides "contr_??.nc". They are averaed over two years long simulations. Variables in the files are: flight_dist_acc: flight distance of the AEDT 2006 inventory for all levels in km/(s*m2) used in the certain simulation cover_tot: cover due to contrail cirrus of all ages and all optical depth, overlapped with the maximum random overlap scheme cover_tot_tau1: cover due to contrail cirrus of all ages and optical depth above 0.02, overlapped with the maximum random overlap scheme cover_tot_tau2: cover due to contrail cirrus of all ages and optical depth above 0.05, overlapped with the maximum random overlap scheme sradt2: SW forcing due to contrail cirrus tradt2: LW forcing due to contrail cirrus sradt2_2: net forcing due to contrail cirrus
