Air quality monitoring for industrial sites
Industrial sites generate complex and variable emission profiles that cannot be understood through periodic sampling alone.
Aernode provides continuous, multi-pollutant monitoring across site boundaries and operational areas, creating structured data for day-to-day oversight, event investigation, documented response and environmental reporting workflows.
Continuous insight for proactive emission management
Continuous operational monitoring shows how air quality changes across the site during day-to-day operations, making short-lived events, recurring patterns and emerging deviations visible as they occur. Used alongside periodic measurements and regulatory sampling, it adds the continuous, high-frequency context that those methods cannot provide between campaigns, without replacing their formal role.
With nodes positioned along the site perimeter and around relevant operational areas, the network helps relate air-quality changes to plant activity and local meteorology, investigate abnormal events and complaints, and act before emerging issues become harder to manage. It creates a persistent layer of environmental oversight for individual facilities and multi-site operations.
Operational value of continuous air quality monitoring
A high-frequency network complements scheduled sampling and regulatory monitoring with continuous visibility across day-to-day site operations.
Continuous monitoring across the site
A distributed network provides a permanent monitoring presence across the facility, revealing short peaks and recurring patterns that periodic campaigns may not capture.
Proactive communication with communities and stakeholders
Continuous site data builds an internal evidence base, relating observed conditions to meteorology and plant activity so teams can explain events, respond to concerns and communicate proactively with external stakeholders.
Active monitoring with configurable alerts
Configurable thresholds and alerts highlight deviations linked to process upsets, loading, maintenance or equipment faults, helping teams investigate and respond before conditions escalate.
Clearer identification of hotspots and plume pathways
Perimeter and source-area nodes show where conditions change and how pollutants move, supporting more targeted inspections, maintenance and mitigation.
Structured data for ESG and management reporting
Consistent time-series records strengthen environmental governance, sustainability disclosures and comparison across sites or reporting periods.
A monitoring network designed around your site
Each deployment is configured around the facility layout, relevant emission sources, exposed receptors and the operational questions the monitoring network must answer.
Define the monitoring objectives
Establish what the network must explain, from boundary conditions and recurring emission patterns to source-area events, abnormal episodes and stakeholder concerns.
Configure and position the network
Select pollutants, meteorological measurements and node locations according to source areas, prevailing winds, exposed receptors and site access conditions.
Establish the operational workflow
Connect measurements to dashboards, alerts, investigation procedures and reporting outputs so that site teams can use the network as an ongoing operational tool.
Pollutants commonly monitored across industrial sites
| Pollutant | Why it matters on industrial sites |
|---|---|
|
PM₂.₅ / PM₁₀
Particulate matter
|
Generated by material handling, crushing, stockpiles, unpaved roads and internal traffic. Distributed PM monitoring helps identify dust peaks, understand local variations and assess how operational activities affect conditions across the site and at its boundary. |
|
VOCs
Volatile organic compounds
|
Associated with solvents, coatings, chemical storage, fuel handling and process releases. Continuous VOC monitoring supports the detection of changing conditions around source areas and the investigation of odour or emission events. |
|
SO₂
Sulphur dioxide
|
Associated with the combustion of sulphur-containing fuels and selected industrial processes. Continuous monitoring helps identify variations around boilers, furnaces and process areas, relate peaks to operating conditions and assess how concentrations change across the site and at its boundary. |
|
H₂S
Hydrogen sulphide
|
Relevant around effluent systems, wastewater processes, waste streams and other decomposition-related sources. Even short variations can be important when investigating odour complaints and relating events to plant activity and wind conditions. |
|
NO₂ / NOx
Nitrogen dioxide and nitrogen oxides
|
Produced by generators, combustion equipment, vehicles and diesel-powered internal logistics. Monitoring helps review conditions around loading areas, transport routes and other operational zones affected by combustion sources. |
|
CO
Carbon monoxide
|
Emitted by incomplete combustion and vehicle engines. Continuous area monitoring is particularly relevant in enclosed or semi-enclosed operational areas where exhaust concentrations may change with traffic and ventilation. |
|
NH₃
Ammonia
|
A project-specific parameter for facilities involving water treatment, refrigeration, chemical handling or agro-industrial processes. It can provide useful context for both operational events and odour-related investigations. |
Aernode supports more than 20 compatible parameters; each station uses a project-specific sensor configuration, while the table shows the options most commonly selected for industrial sites.
