METEOROLOGY (influencing weather conditions A01G15/00; dispersing fog E01H13/00; instruments for measuring single variable in general, see the appropriate subclass of G01, e.g. G01K, G01L; obtaining meteorological information by radar G01S13/95)
Definition statement
This subclass/group 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. G01K, G01L or G01P whereas G01W should 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.
