A '''measurement tower''' or '''measurement mast''', also known as '''meteorological tower''' or '''meteorological mast''' ('''met tower''' or '''met mast'''), is a free standing [[tower]] or a removed [[:wikt:mast|mast]], which carries measuring instruments with [[meteorological]] instruments, such as [[thermometers]] and [[Anemometer|instruments to measure wind speed]]. Measurement towers are an essential component of [[rocket]] launching sites, since one must know exact wind conditions for an execution of a rocket launch. Met masts are crucial in the development of [[wind farms]], as precise knowledge of the wind speed is necessary to know how much energy will be produced, and whether the turbines will survive on the site. Measurement towers are also used in other contexts, for instance near nuclear power stations, and by [[Automated Surface Observing System|ASOS]] stations.
