Taxiing aircraft, auxiliary power units (APUs), and ground support equipment generate concentrated NO₂ and ultrafine particle spikes near gates, aprons, and terminals. These events are short-lived, highly localised, and completely invisible to background monitoring stations positioned away from airside activity. Without continuous, location-specific data, it is impossible to identify hotspots, protect ground crews, manage peak exposure, or demonstrate environmental progress to regulators and surrounding communities.

THE CHALLENGE

Aircraft operations create rapid, localised pollution spikes that standard background monitoring misses entirely.

Aircraft operations create rapid, localised pollution spikes that standard background monitoring misses entirely.

Persium deploys sensor networks around runways, aprons, gates, terminals, and site perimeters, capturing real-time data on aviation-related pollutants as operations happen. Wind data from every sensor adds spatial context, showing how emissions build up, where they disperse, and how conditions change across the day. All data streams into Persium's Dashboard and MapView, giving airport teams a live, connected view of airside environmental conditions they can act on immediately.

WHAT PERSIUM DOES

Continuous, airside-level monitoring, from runway to community boundary.

Continuous, airside-level monitoring, from runway to community boundary.

Airside emissions monitoring

Continuous visibility into take-off, taxiing, and ground operations, across runways, aprons, and taxiways. Real-time data that shows how aviation activity drives pollutant concentrations across the airside environment throughout the day.


Ultrafine particle (UFP) exposure management

Aircraft take-offs can drive ultrafine particle concentrations up to 100x above background levels. Persium measures PM0.3 near runways and terminals, the ultrafine fraction most relevant to jet engine activity, and the one most standard sensors miss entirely.


Gate and ground operations insight

Real-time monitoring near gates captures pollution from APUs and ground support equipment during peak departure windows, enabling operational teams to understand when and where ground-level exposure is highest.

Ground staff and passenger protection

Hyperlocal data identifies the highest-exposure zones for airside crews and terminal staff, providing the evidence needed to implement safer working practices, adjust scheduling, and demonstrate duty of care.

Boundary and community impact monitoring

Perimeter sensors show how airport emissions affect surrounding residential areas and communities, supporting transparent engagement with regulators, local authorities, and the public.

Airport Monitoring Applications

What airports use Persium for.

What airports use Persium for.

Airport air pollution now carries measurable health and financial costs, with mandatory monitoring and reporting requirements expanding across Europe from 2025–2026. NO₂ at gates can exceed 200% of safe limits during peak departure periods.


Ultrafine particles from take-offs are increasingly scrutinised by health regulators. Airports that invest in continuous monitoring now build the evidence base, and the relationships with regulators, that compliance will require. Persium data is time-stamped, exportable, and audit-ready from day one.
