ACTRIS Vocabulary
The aerosol particle phase is comprised of liquid or solid particles, or of liquid particles with a solid core, or of bulk solid material, where the particles are suspended in a gas. The aerosol particle phase excludes the carrier gas. In liquids, molecules flow easily around each other but are held together by attractive forces. In solids, molecules are arranged in a regular pattern, firmly held in place and only able to vibrate within a limited space. A layer has upper and lower boundaries, expressed in some vertical coordinate, where a variable differs significantly from its values outside the layer. Top is the upper boundary of a layer. Altitude is the vertical distance above the geoid.
