+9) gencol.e : compute column densities from concentration, mass and
+              volume ratios
+--------------------------------------------------------------------
+
+Program to compute the column density (kg/m²) from the aerosol mass
+mixing ratios (kg/kg), volume mixing ratio (mol/mol) or concentration
+(cm-3).
+The user provides the input file, from which the routine list all
+relevant tracers. The user then provides the tracers to compute.
+The resulting column densities are stored in a new file.
+
+NB: to compute column density from volume mixing ratiors, the
+atmospheric molecular weigth is required. Be aware that if it is
+impossible to read or compute the local molecular weight, a mean
+will be used.
+
+input : diagfi.nc  / concat.nc / stats.nc kind of files
