ILLIMANI Weather Station configuration

Location: 1639' S; 6747' W at 6265 m (20,555 ft)

A comprehensive discussion of the Sajama station's design and configuration has been published, and is available on-line from the American Meteorological Society. The instrumentation on the Illimani station is somewhat reduced, but quite similar:

Hardy, D.R., M. Vuille, C. Braun, F. Keimig, and R.S. Bradley, 1998: Annual and daily meteorological cycles at high altitude on a tropical mountain. Bulletin of the American Meteorological Society, v. 79, p. 1899-1913.

The Illimani weather station is designed and equipped for year-around data collection at the summit of this Andean peak. It was installed 17 July 1997 near the summit of Illimani by a team from the Climatology Lab (C. Braun and M. Vuille), with assistance from Carlos Escobar and his agency 'Nuevos Horizontes'. All measurements are stored in digital form on-site in two independent locations, and transmitted to the University of Massachusetts via GOES satellite. The station was serviced and upgraded in May of 1998.
