Aspirating Radiation Shield

A device used to shield a sensor such as a temperature probe from
direct and indirect radiation and rain while providing access for
ventilation.

Barometric Pressure

The pressure exerted by the atmosphere as a consequence of
gravitational attraction exerted upon the "column" of air lying directly
above the point in question.

Celsius Temperature Scale

A temperature scale with the ice point at 0 degrees and the boiling point
of water at 100 degrees.

Density Altitude

Density altitude is a meteorological variable that is important to pilots,
especially during the summer. The density altitude is the altitude in a
standard atmosphere where the density is the same as the given
atmospheric density. During a hot muggy summer day, a pilot begins
take off from an airport with an elevation of 2500 feet. Because of the
warm temperature and the moisture in the air, the airplane has to work
as if it was taking off at an airport at an elevation of 6000 feet resulting in
the plane needing more power and a longer roll down the runway to take
off.
Dew Point
The temperature to which a given parcel of air must be cooled at
constant pressure and constant water-vapor content in order for
saturation to occur. When this temperature is below 0°C, it is sometimes
called the frost point.
Fahrenheit Temperature Scale
A temperature scale with the ice point at 32 degrees and the boiling point
of water at 212 degrees.
