Properties:
| Properties | Definition | Type |
|---|---|---|
| DUST | Earth or other solid matter in a minute and fine state of subdivision, so that the particles are small and light enough to be easily raised and carried in a cloud by the wind; any substance comminuted or pulverized; powder. |
enum value |
| VOLCANIC_ASH | Extremely fine particles of pulverized rock, the composition of which, generally speaking, is comprised predominantly of silica (> 50 per cent), together with smaller amounts of the oxides of aluminium, iron, calcium and sodium. |
enum value |
| UNIDENTIFIED | That has not been identified; of which the identity has not been established. |
enum value |
| SPRAY | Ensemble of water droplets torn by the wind from the surface of an extensive body of water, generally from the wave crests, and carried up a short distance into the air. |
enum value |
| SMOKE | Suspension in the atmosphere of small particles produced by combustion. |
enum value |
| SAND | A material consisting of comminuted fragments and water-worn particles of rocks (mainly silicious) finer than those of which gravel is composed. |
enum value |
| MIST | Suspension in the air of microscopic water droplets or wet hygroscopic particles which reduce the visibility at the Earth's surface. |
enum value |
| HAZE | Suspension in the atmosphere of extremely small, dry particles which are invisible to the naked eye but numerous enough to give the sky an opalescent appearance. |
enum value |
| FOG | A suspension of very small, usually microscopic water droplets in the air, reducing visibility at the Earth's surface. |
enum value |
