ITP has three campuses in Lhasa, Beijing and Kunming, respectively. It also operates the Tibetan Observation and Research Platform (TORP), which comprises five field stations on the Tibetan Plateau. They are: the Namco Monitoring and Research Station for Multispheric Interactions; the Southeast Tibet Observation and Research Station for the Alpine Environment; the Qomolangma Atmospheric and Environmental Observation and Research Station; the Muztagh Ata Westerly Observation and Research Station; and the Ngari Desert Observation and Research Station. These facilities make long-term, continuous observations of geophysical, atmospheric and tectonic phenomena to understand land surface processes and environmental changes on the Tibetan Plateau. In addition, ITP has a field network to monitor persistent organic pollutants, one to study stable isotopes in precipitation, and a seismic network to study the deep structure of the Earth and seismicity across the Tibetan Plateau.
