Definition statement

This subclass covers:

Measurement of certain ambient atmospheric conditions.

Adaptations of balloons, missiles, or aircrafts for meteorological purposes.

Radiosondes.

Devices for predicting weather conditions.

Weather houses or similar ornamental devices for indicating humidity.

Sunshine-duration recorders.

Rainfall or precipitation gauges.

Measuring atmospheric potential differences, e.g. due to electrical charges in clouds.

Catathermometers for measuring "cooling value" related either to weather conditions or to comfort of other human environment.

Testing or calibrating meteorological apparatus.

Relationship between large subject matter areas

Instruments for measuring single physical variables, e.g. temperature, pressure or wind speed, should be classified in the appropriate subclasses of class G01, e.g. G01KG01Lor G01P whereas G01Wshould be used for the classification of instruments specializing or combining those measurements for the purpose of deducing, indicating or forecasting weather conditions or meteorological information.

This subclass does not cover:

Radar, sonar, lidar or analogous systems, designed for meteorological use
