Chacaltaya observatory is located in the Andes, at an altitude of 5220 m a.s.l. The observatory has gained worldwide recognition for the observations of cosmic rays since the 1940s.

Since 2012, Chacaltaya is also a station in the Global Atmosphere Watch (GAW) network.

The extreme altitude make the observatory predestined to measure atmospheric composition as representative for the south hemispheric background.

Chacaltaya observatory is operated by the Universidad Mayor San Andrés (UMSA), La Paz, Bolivia.

However, there is considerable international cooperation with researchers from France, Sweden, Germany, Italy, Switzerland, and the USA.
