Instruments
Typical weather stations have the following instruments:
- Thermometer for measuring air and sea surface temperature
- Barometer for measuring atmospheric pressure
- Hygrometer for measuring humidity.
- Anemometer for measuring wind speed
- Rain gauge for measuring liquid precipitation over a set period of time.
In addition, at certain Automated airport weather stations, additional instruments may be employed, including:
- Present Weather/Precipitation Identification Sensor for identifying falling precipitation
- Disdrometer for measuring drop size distribution
- Transmissometer for measuring visibility
- Ceilometer for measuring cloud ceiling
More sophisticated stations may also measure the ultraviolet index, solar radiation, leaf wetness, soil moisture, soil temperature, water temperature in ponds, lakes, creeks, or rivers, and occasionally other data.
