The Sky Quality Meter (SQM) is a small device used to measure the luminance of the night sky. The IAC has installed two of them (SQM-L model) at El Teide (Tenerife) and Roque de los Muchachos (La Palma) observatories, Canary Islands (Spain).

Daytime extinction
We aim at providing a database of diurnal atmospheric extinction data measured using the instrument MARK-I, located at the Observatorio del Teide. Mark-I is a full disk resonant scattering spectrometer providing radial velocity measurements of the Sun at the Potassium KI 769.9 nm line, primarily used to study the solar seismology. Since it is continuously […]
