Temperature to which a specified parcel of air must cool, at constant pressure and water-vapor content, in order for saturation to occur. The dew point is always lower than the wet-bulb temperature, which is always lower than the dry-bulb temperature, except when the air is saturated and all three values are equal. Fog may form when temperature drops to equal the dew point. 

Order given to the airtanker pilot to pick up another load of fire retardant or water and return to the fire.

Assistance in firefighting or investigation by fire agencies, without regard for jurisdictional boundaries.

To search for a small fire by systematically traveling over an area on parallel courses or gridlines.

Any light, mobile unit with limited pumping and water capacity.

Dropping by an airtanker of its entire load of fire retardant at one time.

The place where plant communities meet or where successional stages or vegetative conditions within plant communities come together.

A manufactured unit consisting of five interconnecting tanks, a control pallet, and a nozzle pallet, with a capacity of 3,000 gallons, designed to be rapidly mounted inside an unmodified C-130 (Hercules) cargo aircraft for use in cascading retardant chemicals on wildfires. 

The final phase of combustion following flaming and smoldering phases.

The process of oxidation of solid fuel accompanied by incandesence. All volatiles have already been driven off, oxygen reaches the combustion surfaces, and there is no visible smoke. This phase follows the smoldering combustion phase and continues until the temperature drops below the combustion threshold value, or until only non-combustible ash remains.
