Dear Dr. Wolf,

I now have two second reviews. Both identify substantial remaining concerns with technical aspects of the paper and the discussion of the microphysics, concerns that I share myself. I believe that each of the concerns raised can be relatively easily addressed without taking away from the substantial observational contribution of what is currently described.

My own particular concern is an apparent treatment of cirrus cloud particles as passive tracers. This may be true to some extent if the particles are large enough to precipitate, but in the growth phase, clouds are constantly decay and regenerating in buoyant updrafts, interacting with their environment such that their "memory" of their initial conditions decays rather rapidly with time.

Regards,

Tim Garrett
