The Mount Washington Observatory (MWObs) is a private, non-profit scientific and educational institution organized under the laws of the state of New Hampshire. The weather observation station is located on the summit of Mount Washington in New Hampshire. The first regular meteorological observations on Mount Washington were conducted by the U.S. Signal Service, a precursor of the Weather Bureau, from 1870 to 1892.




History



The U.S. Signal Service, a predecessor to the Weather Bureau, occupied the summit and kept records from 1870 to 1892. Starting in 1932, the current observatory began keeping records. On April 12, 1934, the observatory staff recorded a wind gust of 231 mph that at the time was the highest recorded wind speed in the world, a record that was held until 1996. The observatory's weather data have accumulated into a valuable climate record since. Temperature and humidity readings have been collected using a sling psychrometer, a simple device containing two mercury thermometers. Where most unstaffed weather stations have undergone technology upgrades, consistent use of the sling psychrometer has helped provide scientific precision to the Mount Washington climate record.
The observatory makes prominent use of the slogan "Home of the World's Worst Weather", a claim that originated with a 1940 article by Charles Brooks (the man generally given the majority of credit for creating the Mount Washington Observatory), titled "The Worst Weather In the World" (even though the article concluded that Mt. Washington most likely did not have the world's worst weather). The Sherman Adams summit building, named for the 67th Governor of New Hampshire, houses the observatory; it is closed to the public during the winter and hikers are not allowed inside the building except for emergencies and pre-arranged guided tours.

Partners


The Mount Washington Observatory receives much of its support from contributing members. However, over the years the MWObs has also come to receive support from several company and organizational partners, including L.L. Bean, Eastern Mountain Sports (EMS), Cranmore Mountain Resort, the Mt. Washington Auto Road, and the Mt. Washington Valley Chamber of Commerce. In 2011, EMS replaced L.L. Bean as the official outfitter of the Observatory.
The United States Postal Service maintains a small post office for outgoing mail, located in the Sherman Adams building at the summit; the ZIP Code is 03589.
