METEOROLOGY (radar, sonar, lidar or analogous systems, designed for meteorological use G01S13/95, G01S15/88, G01S17/95)

Introduced: September 1968

Description

G01W covers instruments and methods for measuring meteorological phenomena and atmospheric conditions. This includes devices for measuring temperature, humidity, atmospheric pressure, wind speed and direction, precipitation, cloud formation, and other weather-related parameters. The classification encompasses weather stations, radiosondes, barometers, anemometers, rain gauges, and associated data collection systems used in meteorological observation and forecasting. Applications extend from basic weather monitoring to climate research and atmospheric science studies.
