Absorbance is defined as "the logarithm of the ratio of incident to transmitted radiant power through a sample. Absorbance 260nm describes the absorbance at a wavelength of 260 nm.

"Equivalent reflectivity factor" is the radar reflectivity factor that is calculated from the measured radar return power assuming the target is composed of liquid water droplets whose diameter is less than one tenth of the radar wavelength, i.e., treating the droplets as Rayleigh scatterers. The actual radar reflectivity factor would depend on the size distribution and composition of the particles within the target volume and these are often unknown.

equivalent_reflectivity_factor, unit is dBz - and please note that 'reflectivity' itself would not be appropriate here. In addition the description there relates to the unit. This has to be changed there

The movement velocity is the speed of an object derived from the change in its position over time.

No provenance found. This velocity comes for example from GPS data.

Number concentration of aerosol particles in air

# data[].attributes.definition
"Number concentration" means the number of particles or other specified objects per unit volume. "Aerosol" means the system of suspended liquid or solid particles in air (except cloud droplets) and their carrier gas, the air itself.

Specific Differential Phase (KDP) is a derived product that shows the gradient, or change, in Differential Phase Shift (ΦDP). Positive KDP values indicate greater phase shift in the horizontal than the vertical.
Increasing KDP is an indication of an increase in the size and concentration of rain drops, and thus, an increase in rain rate. This means that KDP is useful for pinpointing areas where the heaviest rainfall is occurring.

Radial velocity of scatterers, away from instrument

# data[].attributes.definition
A velocity is a vector quantity. "Radial velocity away from instrument" means the component of the velocity along the line of sight of the instrument where positive implies movement away from the instrument (i.e. outward). The "instrument" (examples are radar and lidar) is the device used to make the observation. The "scatterers" are what causes the transmitted signal to be returned to the instrument (examples are aerosols, hydrometeors and refractive index irregularities), of whatever kind the instrument detects. A standard name referring to radial velocity "toward_instrument" should be used for a data variable having the opposite sign convention.

The ratio of the mass of a variable atmospheric constituent to the mass of dry air.

# data[].attributes.note
common unit is g/kg even though this would be dimensionless, entry in cf-conventions list: 'humidity_mixing_ratio' (Humidity mixing ratio of a parcel of moist air is the ratio of the mass of water vapor to the mass of dry air) is a good description, but the expressing humidity mixing ratio' is hardly in use
