GRIB:

the aerosol optical property of asymmetry factor (ratio of forward to backward scattered energy) for our benchmark radiative transfer calculations. If the variable with short name "aerext" is "spectral_volume_extinction_coefficient_in_air_due_to_ambient_aerosol_particles", then we would propose naming this variable "spectral_volume_asymmetry_factor_in_air_due_to_ambient_aerosol_particles". (In our original request, this variable was specified by the Short name "aerasym".)

GRIB:

The specification of a physical process by the phrase "due_to_" process means that the quantity named is a single term in a sum of terms which together compose the general quantity named by omitting the phrase. "Aerosol" means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself. "Ambient_aerosol" means that the aerosol is measured or modelled at the ambient state of pressure, temperature and relative humidity that exists in its immediate environment. "Ambient aerosol particles" are aerosol particles that have taken up ambient water through hygroscopic growth. The extent of hygroscopic growth depends on the relative humidity and the composition of the particles. To specify the relative humidity and temperature at which the quantity described by the standard name applies, provide scalar coordinate variables with standard names of "relative_humidity" and "air_temperature".

The asymmetry coefficient is the ratio of forward to backward scattered radiative flux. The asymmetry coefficient is assumed to be an integral over all wavelengths, unless a coordinate of radiation_wavelength is included to specify the wavelength.

The term "shortwave" means shortwave radiation. The asymmetry factor is the angular integral of the aerosol scattering phase function weighted by the cosine of the angle with the incident radiation flux. The asymmetry coefficient is assumed to be an integral over all wavelengths, unless a coordinate of radiation_wavelength is included to specify the wavelength. "Aerosol" means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself.
