The Royal Meteorological Society is a long-established institution that promotes academic and public engagement in weather and climate science. Fellows of the Society must possess relevant qualifications, but Associate Fellows can be lay enthusiasts. Its Quarterly Journal is one of the world's leading sources of original research in the atmospheric sciences. The chief executive officer is Liz Bentley. Constitution The Royal Meteorological Society traces its origins back to 3 April 1850 when the British Meteorological Society was formed as "a society the objects of which should be the advancement and extension of meteorological science by determining the laws of climate and of meteorological phenomena in general". Along with nine others, including James Glaisher, John Drew, Edward Joseph Lowe, The Revd Joseph Bancroft Reade, and Samuel Charles Whitbread, Dr John Lee, an astronomer, of Hartwell House, near Aylesbury, Buckinghamshire founded in the library of his house the British Meteorological Society, which became the Royal Meteorological Society. It became The Meteorological Society in 1866, when it was incorporated by Royal Charter, and the Royal Meteorological Society in 1883, when Her Majesty Queen Victoria granted the privilege of adding 'Royal' to the title. Along with 74 others, the famous meteorologist Luke Howard joined the original 15 members of the Society at its first ordinary meeting on 7 May 1850. As of 2008 it has more than 3,000 members worldwide. The chief executive of the Society is Professor Liz Bentley. Paul Hardaker previously served as chief executive from 2006 to 2012.
