Automatic Weather Stations for Civil Aviation
Aerodrome decisions depend on the weather being measured correctly, continuously and to international standard. We supply, install, commission and maintain automatic weather stations and aviation meteorological observation systems: unified weather intelligence for safer, more efficient airport operations, and for mines and industrial sites that need defensible on-site meteorology.
Wind speed & direction
Ultrasonic and mechanical anemometry sited to aerodrome standards, with runway-referenced reporting.
Temperature & humidity
Shielded, ventilated sensing for accurate air temperature, dew point and relative humidity.
Barometric pressure
QNH, QFE and pressure altitude to the precision aviation reporting requires.
Visibility & present weather
Forward-scatter visibility, RVR and present-weather identification for low-visibility procedures.
Cloud height & ceiling
Ceilometry for cloud base height and vertical visibility reporting.
Lightning detection
Thunderstorm detection and ramp-safety alerting to protect ground crews and operations.
Integrated, standards-aligned & future-ready
- Aligned to ICAO Annex 3 and WMO observation practice
- Data delivered to ATC, MET services and airport operations
- Scalable, modular architecture, so you can add sensors as needs grow
- Secure, resilient data handling and redundancy by design
- Calibration, servicing and data-quality assurance programmes
Beyond the runway
The same observation backbone underpins our exposure science. On-site meteorology is the input that makes dispersion modelling defensible, wind roses, stability classes and mixing heights feeding AERMOD and CALPUFF, and driving dust, odour and emissions predictions for mines, tailings facilities and industrial neighbours.
Stack & Point-Source Emissions Monitoring
What leaves the stack determines what the community breathes. We measure point-source emissions to recognised isokinetic and instrumental methods, then connect those results to dispersion modelling and community exposure assessment, closing the loop between the emission point and the receptor.
What we measure
- Particulate matter: isokinetic sampling of total & filterable PM
- Combustion gases: SO₂, NOₓ, CO, CO₂ and O₂ reference conditions
- Acid gases: HCl, HF, H₂S, NH₃, Cl₂ and HCN
- Organics: TVOC, PAH, dioxins and furans, and PCB
- Metals including mercury, and hexavalent chromium
- Stack gas velocity, flow rate, temperature and moisture
How we deliver it
- Sampling-plane assessment and port suitability review
- Documented chain of custody from stack to laboratory
- Mass emission rates normalised to reference conditions
- Comparison against BOS 807:2023 and your permit limits
- CEMS calibration and correlation, and abatement verification
- Emission data prepared as AERMOD / CALPUFF model input
Air Quality Monitoring with Low-Cost Sensor Networks
A single reference station tells you what the air was like at one point. A network tells you where the problem is. We deploy dense arrays of calibrated low-cost sensors across mine boundaries, industrial fencelines and communities, then apply the exposure science that turns cheap sensor signals into decision-grade data.
Density over scarcity
Many nodes instead of one station, resolving hotspots, gradients and fenceline variation that a single monitor cannot see.
Real-time & continuous
Live PM2.5, PM10 and gas readings streamed to dashboards, with threshold alerting when conditions deteriorate.
Reference-calibrated
Co-location against reference-grade instruments with correction for humidity and drift, the step that makes the data defensible.
Why this is different
Sensors are the easy part. The science is the value.
Anyone can hang a sensor on a fence. Uncalibrated low-cost sensors drift, respond to humidity and mis-size particles, which is why so much sensor data is dismissed the moment it is challenged. We treat the network as an exposure-assessment instrument: co-located calibration, correction models, data-quality flagging, and interpretation against ambient guidelines with uncertainty stated. That is what makes the output usable for community engagement, regulators and, if it ever comes to it, a courtroom.
Applications
- Mine boundary and haul-road dust surveillance
- Tailings facility fenceline and downwind community monitoring
- Industrial fenceline and neighbourhood air quality
- Urban and community exposure studies
- Construction and demolition dust management
What you receive
- Network design: siting informed by wind rose and source layout
- Live dashboards with exceedance and trend alerting
- Source apportionment and hotspot identification
- Integration with dispersion modelling and Risk Exposome360°
- Reporting against WHO and national ambient guidelines
