The Institut de radioastronomie millimétrique (IRAM) operates two observatories at millimetre wavelengths, which are open to the international astronomical community: The 30-m single-dish telescope on Pico Veleta (2850 m), located in Sierra Nevada (Spain), and the six-antenna interferometer on the Plateau de Bure (2550 m) in the French Alps. Both sites are at high altitude to reduce the absorption by water vapour. The observatories are supported by the IRAM offices and laboratories in Granada and Grenoble. IRAM, which is directed by Pierre Cox, has its headquarters in Grenoble.
