Dear Alejandro,
just one small comment.
We had recently a long discussion concerning wording of a few aerosol variables,
and some results of that discussion would also be relevant for your proposed
variable. You should probably substitute "cloud" with "cloud_particles".
Otherwise, it isn't clear whether you refer only to the cloud particle phase, or
to the whole system of particles and air. Also, you probably want to require a
co-ordinate variable "wavelength" in the definition.
Best regards,
Markus

"Extinction" is the term most commonly used at optical wavelengths whereas "attenuation" is more often used at radio and radar wavelengths. "Cloud" means suspended liquid or ice water droplets.
