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.

Famous quotes containing the word instruments:
“Water, earth, air, fire, and the other parts of this structure of mine are no more instruments of your life than instruments of your death. Why do you fear your last day? It contributes no more to your death than each of the others. The last step does not cause the fatigue, but reveals it. All days travel toward death, the last one reaches it.”
—Michel de Montaigne (1533–1592)
“The worth of a State, in the long run, is the worth of the individuals composing it ... a State which dwarfs its men, in order that they may be more docile instruments in its hands even for beneficial purposes—will find that with small men no great thing can really be accomplished.”
—John Stuart Mill (1806–1873)
“Being the dependents of the general government, and looking to its treasury as the source of all their emoluments, the state officers, under whatever names they might pass and by whatever forms their duties might be prescribed, would in effect be the mere stipendiaries and instruments of the central power.”
—Andrew Jackson (1767–1845)
