Cerro Chajnantor
The candidate site for CCAT is at 5612 m altitude about 200 m ENE and 50 m below the summit of Cerro Chajnantor. To evaluate environmental and observing conditions there, a weather station and other instrumentation were deployed in 2006 May. The meteorological data are available here in graphic and in text files.
Other locations
In the past, weather stations have been deployed at several other sites of interest. Data from those stations are also available.Cerro Negro
