 A little more on preparations of these input files, particularly for aquaplanet slab ocean.
 
-- The 'qlfx' file is normally obtained by first running a slab ocean aquaplanet with zero flux correction in order to get the climatological SST. The SST is then used to run a pure aquaplanet run with prescribed SST so that we can then compute the surface flux. This surface flux then requires post-processing to get a climatological (12 months) zonally invariant and hemispherically symmetric flux file, that is then used as an input to the slab ocean part.
 - Ozone file needs a vertical profile to ensure radiative properties of the stratosphere and troposphere, but for an aquaplanet slab ocean, we would need zonally invariant and hemispherically symmetric ozone concentrations. 
 - Solar irradiance must have no seasons. Here, we ensure eccentricity and obliquity is also set to zero. However, all these do not account for varying zenith angle of the sun. 
+- 'qfl' file: The simplest option is to use no correction 'qflx=0' everywhere. Here, the system would respond to the forcing and can arrive at a different mean state climate, fully free to evolve. 
+- 'qflx' file to constrain to the same climate mean state. Here, the 'qlfx' file is normally obtained by first running a slab ocean aquaplanet with zero flux correction in order to get the climatological SST. The SST is then used to run a pure aquaplanet run with prescribed SST that has been post-processed (i.e. climatological mean, zonally averaged, hemispherically symmetric) for about 20 years, and from which we can get the surface flux associated with the mean climate state. This surface flux then requires post-processing to get a climatological mean, zonally invariant and hemispherically symmetric flux file, that is then used as the 'qflx' file input to the actual aquaplanet slab ocean run.
