Same as Aeolian.

Extended Binary Coded Decimal Interchange Code. A standard code used to represent data using 8 bits per character.

A component of the wind (often using Cartesian coordinates. i.e. X and Y wind vectors). Also, an arrow representing wind velocity, drawn to point in the direction of the wind and with a length proportional to wind speed.

Formation of a single water drop by the union of two or more colliding drops.

An instrument which measures the spectral distribution of the intensity of direct solar radiation.

Eluding precise prediction, completely irregular.

In general, solar radiation received at the earth's surface. Contracted from incoming solar radiation.

A type of anemometer in which the rotation of an element serves to measure the wind. Rotation anemometers are divided into two classes; those in which the axis of rotation is horizontal, such as the windmill anemometer, and those in which the axis of rota ...

Difference between the instantaneous wind velocity at a point and the mean wind velocity taken over a given time interval. Also called fluctuation velocity.

The smallest change in the environment that causes detectable change in the indication of an instrument. Compare to sensitivity.

Pertaining to measurements or devices in which the output vanes in discrete steps, i.e. on-off or pulse signals. Compare to analog.

Same as water year.

An apparatus, used in studying soil temperatures, for measuring the total supply of heat during a given period.

A common unit used in measurement of atmospheric pressure. Defined as that pressure exerted by a one-inch column of mercury at standard gravity and a temperature of 0'C.

The cardinal points of the compass, i.e. north, south, east, west.

Downward-facing pyranometer used for measuring reflected solar radiation.

A temperature telemeter.

An air-launched balloon designed to be released in the eye of a tropical cyclone, float within the eye at predetermined levels, and transmit radio signals for RDF positioning.

Same as dew-point hygrometer.

A unit of energy equal to 101 ergs or to 0.2389 calories.
