DEFINITION

Classification: 73/170.16

METEOROLOGY:

(under the class definition) Subject matter comprising an apparatus or method for determining an atmospheric phenomenon or a weather condition.

(1) Note. This subclass generally contains subject matter drawn to the measurement of plural meteorological conditions. However, the measurement of a single meteorological condition, not provided for elsewhere, is also found here.

SEE OR SEARCH THIS CLASS, SUBCLASS:

28.01, for measuring solids in the atmosphere other than micrometeorites.

29.02, for a hygrometer, per se.

31.02, for testing for impurities of the air.

170.01+, for a meteorological apparatus or process combined with wind direction determining. 384+, for a barometer.

861.79, for an anemometer, per se.

863+, for a sampler, per se, which may obtain a sample of the atmosphere.

116, Signals and Indicators,

69, for a mechanical alarm or indicator, per se, providing a humanly perceptible signal in response to a predetermined rain condition and subclasses 264+ for a mechanical indicator providing a humanly perceptible signal in response to the presence or absence of fluid flow.

244, Aeronautics,

134, for the prevention of ice on aircraft structure.

340, Communications: Electrical,

580+, for an electrical indicator which produces a humanly perceptible signal in response to the attainment of a predetermined icing condition.

342, Communications: Directive Radio Wave Systems and Devices (e.g., Radar, Radio Navigation),

26, for weather radar, per se. 364, Electrical Computers and Data Processing Systems,

420, for an electrical computer data processing system applied to the weather.

374, Thermal Measuring and Testing, appropriate subclass for atmospheric temperature measuring, per se,

109, for temperature combined with another atmospheric condition (e.g., discomfort index, windchill factor) and subclass 143 for significant temperature measuring combined with nonmeteorological pressure measuring.
