Measurement and statistical analysis of those parameters related with the atmospheric turbulence are crucial for the selection and characterization of best astronomical observing sites. These parameters require continuously monitoring and updating.

The Instituto de Astrofísica de Canarias (IAC) has long been aware of the importance of promoting initiatives for the characterization and protection of the Observarorio del Roque de los Muchachos (ORM) on La Palma, and the Observatorio del Teide (OT) on Tenerife. For this purpose, in the late 80's a Sky Quality Group ( This e-mail address is being protected from spam bots, you need JavaScript enabled to view it ) was created as well as a technical office for sky protection (OTPC).

This website has been set up to provide detailed information and statistics about meteorological and seeing data at different locations at the Canarian Observatories, by means of different instruments and campaigns. Data files and charts are also available, as well as other related information.

 The Site Characterization study is funded by the IAC and co-funded by EECC FP6 programme (ELT telescope design study, also IAC Web Page ) , Opticon (Optical Infrared Co-ordination Network for Astronomy), Co-ordination and Integration of ENO facilities.
