During the second half of 2020, TBI installed two Purple Air sensors, one at TBI-Ileret and the other at TBI-Turkwel. These sensors measure smoke, dust, and other particulate air pollution, as well as keeping track of local temperature. By installing these sensors, TBI’s facilities will join an international, open-source air quality monitoring network facilitated by the Purple Air platform.

The sensors measure PM2.5 and PM10 – particulates of 2.5 and 10 micrometers or less respectively. The concentration of these particulates has implications for climate change and health, and is influenced by local factors such as localized combustion, as well as global trends in air quality.
