Field Measurement Services

Aerodyne’s mobile laboratory(ies) and instruments have participated in numerous field campaigns focusing on a great variety of scientific areas.

Neighborhood Mapping for Pollution Impact

The fast-response online measurement methods aboard the mobile laboratory enables us to map spatial gradients of emitted pollutants.

Tracer Release Studies

Tracer release methodology [Roscioli et al., 2015] is used to quantify emissions at industrial facilities like natural gas well pads, compressor stations, dairy farms, and more. These studies rely on releasing small quantities of one or more tracer gases like nitrous oxide (N2O), acetylene (C2H2) or ethane (C2H6) at or near to a facility. The tracer gases co-disperse with any site emissions like methane (CH4), and are measured downwind by the mobile laboratory. The tracer release method allows for accurate and complete facility-scale emission quantification, with typical uncertainties better than 50%.

Fenceline Monitoring and Leak Detection

The mobile laboratory can be operated in “survey mode” for real-time detection and source identification of equipment leaks.

Alternative Platform Deployments:

Some studies require deployment of instrumentation on other vessels, like aircraft, ships or containers. Aerodyne has installed instruments or suites of instruments aboard aircraft and ships of varying sizes.

Research and commercial instruments are installed into the Mobile Laboratory to collect data while in motion for plume characterization, area mapping or portable deployment for photochemistry and transport experiments.

Instruments on the Mobile Laboratory

The Aerodyne Mobile Laboratory has a suite of instrumentation that changes depending on the requirements of the measurement campaign.

Aerodyne-manufactured instruments:

Non-Aerodyne commercially available instruments:

  •     GPS position and GPS compass
  •     2D or 3D anemometers
  •     Commercial systems for measuring NOx, NO

Research-grade instrumentation is often integrated into the mobile laboratory by project collaborators:

And the Mobile Laboratory has been host to numerous research and commercial instruments from collaborators.
