standard_name :: mass_fraction_of_cloud_liquid_water_in_air
long_name :: Mass Fraction of Cloud Liquid Water
comment :: Includes both large-scale and convective cloud. Calculate as the mass of cloud liquid water in the grid cell divided by the mass of air (including the water in all phases) in the grid cells. Precipitating hydrometeors are included ONLY if the precipitating hydrometeors affect the calculation of radiative transfer in model.

history :
Model output postprocessed with Afterburner and CDO (https://code.zmaw.de/projects) 2011-12-05T01:38:45Z CMOR rewrote data to comply with CF standards and CMIP5 requirements.
comment :
Equilibrium reached after more than 1500-year spin-up at pre-industrial GHG concentrations after which data were output with nominal date of January 1850.
