Industry:Weather
The quantity to be measured (or modulated, or detected, or operated upon) that is received by an instrument. Thus, for a thermometer, temperature is the input quantity.

Industry:Weather
A general term for instruments that sample particles suspended in the atmosphere by impaction. This instrument is based on the principle that particles in an airstream will continue in a straight line due to their inertia when the flow of the air bends sharply; if a surface to which they can adhere is present, they will strike it and may stick. See cascade impactor, rotating multicylinder; compare collector.

Industry:Weather
The boundary surface in the atmosphere between a haze layer and the relatively clean, transparent air above; the top of a haze layer. This “line” usually exists near the base of a temperature inversion that prevents the upward spreading of the haze particles. It is frequently a very distinct discontinuity and is particularly striking when viewed from an aircraft that is either just passing through it or is flying high aloft with the sun above the horizon. In the latter case, glare due to the upward scattering of sunlight from the haze can produce a very limited cone of visibility. See also haze horizon.

Industry:Weather
A line drawn through all points on the earth's surface having the same magnetic inclination. The particular isoclinic line drawn through points of zero inclination is given the special name of aclinic line. Compare isogonic line, isocline.
Industry:Weather
A loop in the path of a parcel in inertial flow, which is approximately circular if the latitudinal displacement is small.
