BackForward Variable: Aerosol volcanic ash

Full name Aerosol volcanic ash
Definition 3D field of mass mixing ratio of volcanic ash
Measuring Units g/kg Uncertainty Units %
Horizontal Res Units Vertical Res Units
Stability Units % (Stability /decade)


Comment: "Volcanic ash" is a required component of the pre-defined set of aerosol classes from which the aerosol type is chosen. The value reported for "volcanic ash" is the aerosol mass mixing ratio multiplied by the mass fraction of volcanic ash in the aerosol class chosen as the aerosol type.
