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:
“I rejoice that America has resisted. Three millions of people, so dead to all the feelings of liberty, as voluntarily to submit to be slaves, would have been fit instruments to make slaves of the rest.”
—William Pitt, The Elder, Lord Chatham (1708–1778)
“The form of act or thought mattered nothing. The hymns of David, the plays of Shakespeare, the metaphysics of Descartes, the crimes of Borgia, the virtues of Antonine, the atheism of yesterday and the materialism of to-day, were all emanation of divine thought, doing their appointed work. It was the duty of the church to deal with them all, not as though they existed through a power hostile to the deity, but as instruments of the deity to work out his unrevealed ends.”
—Henry Brooks Adams (1838–1918)
“I lay my eternal curse on whomsoever shall now or at any time hereafter make schoolbooks of my works and make me hated as Shakespeare is hated. My plays were not designed as instruments of torture. All the schools that lust after them get this answer, and will never get any other.”
—George Bernard Shaw (1856–1950)
