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.
