Short summary
This paper focuses on the demonstration and assessment of thermal infrared laser heterodyne spectro-radiometry for the remote sensing of carbon dioxide (CO2). A research instrument has been developed and operated from the ground using direct sunlight to measure CO2 to a high precision. This technology would enable the development of high-performance miniature ground-based sounders to complement existing measurement networks and contribute to the improvement of global carbon emission assessment.
