If 'moderate snow' is going out on the ATIS, its the intensity of the current precipitation that is being reported, not the physical amount/volume of snow. The report is created by the use of a combination of semi-automated weather monitoring system, plus a good ol' Mk1 Eyeball observation by the VCR ATSA - all done as per the local instructions/Met Office reporting criteria.
When there really is 'buckets of snow' on the ground, then it is the responsibility of the Airfield Operator to advise the VCR ATSA of the constitution and depth of snow, and the braking action, both of which will then be included in the ATIS broadcast.
