Properties:
| Properties | Definition | Type |
|---|---|---|
| DRIZZLE | Fairly uniform precipitation in very fine drops of water (diameter less than 0.5 mm) very close to one another, falling from a cloud. |
enum value |
| UNKNOWN | Unknown precipitation. |
enum value |
| UNIDENTIFIED | Unidentified precipitation. |
enum value |
| SUPERCOOLED_LARGE_DROPLET | Liquid droplets with diameters greater than 0.05 mm (50 microns) at temperatures less than 0�C, i.e., freezing rain or freezing drizzle. Due to their relatively large size and high mass, SLD are particularly hazardous to aircraft, since they can impact the aircraft surfaces outside the ice-protected regions. |
enum value |
| SNOW_PELLETS | Precipitation of white and opaque ice particles, which fall from a cloud and which are generally conical or rounded, with diameters attaining as much as 5 mm. |
enum value |
| SNOW_GRAINS | Precipitation of very small opaque white particles of ice which fall from a cloud and which are fairly flat or elongated with diameters generally less than 1 mm. |
enum value |
| SNOW | Precipitation of ice crystals, isolated or agglomerated, falling from a cloud. |
enum value |
| SMALL_HAIL | Precipitation of translucent ice particles, which falls from a cloud. These particles are almost always spherical and sometimes have conical tips. Their diameter may attain or even exceed five millimetres. |
enum value |
| RAIN | Precipitation of liquid water particles, either in the form of drops of more than 0.5 mm in diameter, or of smaller widely scattered drops. |
enum value |
| ICE_PELLETS | Precipitation of transparent particles of ice which are spherical or irregular, rarely conical, and which have a diameter of 5 mm or less. |
enum value |
| ICE_CRYSTALS | Any one of a number of macroscopic crystalline forms of ice including hexagonal columns and platelets, dendritic crystals, ice needles and their combinations. |
enum value |
| HAIL | Precipitation of either transparent, or partly or completely opaque particles of ice (hailstones), usually spheroidal, conical or irregular in form and of diameter very generally between 5 and 50 millimetres, which falls from a cloud either separately or agglomerated into irregular lumps. |
