Pandonia Global Network (PGN)

Pandonia Global Network (PGN)

In 2005 NASA initiated an effort at Goddard Space Flight Center (GFSC) to address the gap in validation measurements by developing a cost-effective, easily deployable, ground-based spectrometer called Pandora.

NASA and the European Space Agency (ESA) collaborated to coordinate and facilitate an expanding global network of standardized, calibrated Pandora instruments focused on air quality and atmospheric composition. The creation of this network ensures systematic processing and dissemination of data to the greater global community in support of in-situ and remotely sensed air quality monitoring. This effort is known as the Pandonia Global Network (PGN), consisting of SciGlob’s Pandora instruments at the locations shown on the map above.

The first deployment of SciGlob’s Pandora Spectrometer took place in 2005 in Greece. Its success led to the official launch of the PGN in mid-2019, resulting in the establishment of fixed long-term Pandora installment locations. These installments focused on providing long-term quality observations of the total column and vertically resolved concentrations of a range of trace gases. As of 2021, over 100 Pandora Spectrometers have been deployed globally, and PGN has and continues to provide real-time air quality data.
