Unreferenced stub auto yes date December 2009 Image Disdrometer.jpg thumb A disdrometer in place in the Everglades . A disdrometer is an instrument used to measure the drop size distribution and velocity of falling precipitation meteorology hydrometeors . Some disdrometers can distinguish between rain , graupel , and hail . The uses for disdrometers are numerous. They can be used for traffic control , scientific examination, airport observation systems, and hydrology . The latest disdrometers employ microwave or laser technologies. 2D video disdrometers can be used to analyze individual snowflake s.

- SCR-658 radar
The SCR 658 radar was developed in conjunction with the SCR 268 radar . It was preceded by the SCR 258. Its primary purpose was to track weather balloons. Prior to this it was only possible to track weather balloons with a theodolite , causing difficulty with visual tracking in poor weather conditions. The set is small enough to be portable and carried in a Ben Hur trailer .

- Weather station
Image Mildura Airport Weatherstation.jpg right thumb Weather station at Mildura Airport , Victoria, Australia . A weather station is a facility, either on land or sea, with instruments and equipment for observing Earth s atmosphere atmospheric conditions to provide information for weather forecasting weather forecasts and to study the weather and climate . The measurements taken include temperature , barometric pressure , humidity , wind speed , wind direction , and precipitation meteorology precipitation amounts. Wind measurements are taken as free of other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation . Manual observations are taken at least once daily, while automated observations are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature , wave height, and wave period. Drifting weather buoy s outnumber their moored versions by a significant amount. 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 station s, 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. Exposure Except for those instruments requiring direct exposure t ... more details
