The Pandonia Global Network

The launch

of PGN in mid-2019 represents a programmatic shift by NASA and ESA towards establishing long-term fixed locations focused on providing long-term quality observations of total column and vertically resolved concentrations of a range of trace gases. A major joint objective is to support the validation and verification of more than a dozen low-earth orbit and geostationary orbit based UV-visible sensors.


provides real-time, standardized, calibrated and verified QA/QC AQ data. PGN also seeks to coordinate and implement network standards regarding common algorithms and data processing, instrument operating routines, QA/QC, real-time data processing and data archiving. PGN participants are primarily comprised of governmental and academic researchers and technicians.
