Overview

Investigation demonstrates the potential of lidar for measuring CO2 isotopic ratios in the atmosphere, indicating future applications.

Key Points

  • The study aims to evaluate the ability of a lidar system to measure the isotopic composition of CO2 in the atmosphere, focusing on δ13C.
  • Developed a coherent differential absorption lidar (CDIAL) to measure 12CO2 and 13CO2 separately.
  • Conducted atmospheric measurements over three days above Ecole Polytechnique campus.
  • Employed in situ gas analyser measurements to correct for biases.
  • Achieved a precision of around 0.6% for 12CO2 mixing ratio over 1.2 km range.
  • Obtained a precision of approximately 3.2% for 13CO2 mixing ratio over 1.6 km range.
  • Established a basis for future development of optimized lidar instruments.
