WFS International meteorological monitoring tracks key atmospheric parameters. Basic parameters: temperature, humidity, air pressure, and wind speed and direction. Precipitation and radiation: rainfall, snowfall, solar irradiance, and UV index. Extreme weather indicators: lightning, visibility, PM2.5, and other pollutants. Main devices: weather stations with integrated radiation sensors, wind monitoring sensors, and temperature, humidity, and pressure sensors, plus satellites and LiDAR. Applications include disaster alerts, tracking typhoons and rainstorms; agricultural optimization, guiding planting and harvesting with climate data; urban air quality management, helping mitigate smog and heat islands (for example, Beijing air quality management); and energy management, supporting wind and solar farm operations (for example, Xinjiang wind power bases).
