State-of-the-art instruments for trace gas measurements using micrometeorological techniques

Real-time, continuous field-scale measurement of greenhouse gas emissions from farms.

We have a suite of sophisticated instruments for gas measurements that offer high resolution of dynamic real-time measurement and monitoring of key direct and indirect greenhouse gases (CO2, CH4, N2O, NH3), including:

  • Open-path Fourier Transform Infrared (OP-FTIR) spectrometer
  • Closed-path FTIR spectrometer
  • Quantum Cascade Lasers (QCLs)
  • Open-path lasers.

Coupled with advanced advection-dispersion modelling and high-resolution environmental sensors, we are able to determine the spatial and temporal variation of greenhouse gas emission, transport and deposition.

Quantum Cascade Lasers have high precision (ppt levels) and high response (10Hz) for NH3, N2O and CH4 which can be used for the Eddy Covariance tower to measure large-scale and long-term greenhouse gas emission and NH3 dry deposition. We have also integrated QCL with the aircraft for regional scale greenhouse gas measurements.
