Abstract

Major astronomical observatories operating in the visible/infrared spectrum are often equipped with weather stations to monitor key parameters that affect the quality of the observations obtained. Most of these monitoring efforts have now spanned a 30-year timeframe, making it possible to investigate whether there are climatic variations in the data. The study was therefore conducted at numerous sites, particularly at the Cerro Paranal Observatory (Chile), home to the Very Large Telescope, and the Mauna Kea Observatory (Hawaii), home to the Canada-France-Hawaii Telescope. However, an astronomical observatory is more than just a set of physical quantities; one must also take into account the entire ecosystem that enables an observatory to operate effectively…
