FLAIR team performed a week-long measurement campaign

The FLAIR team performed a week-long measurement campaign over the waters of the Kategatt, the strait linking the Nord Sea with the Baltic Sea. In collaboration with Explicit, a Danish company specialized in airborne pollutant detection, and Charlie9, a Helicopter company based near Copenhagen, more than 120 ships could be targeted, and their exhaust fumes analyzed. The FLAIR system has been tuned to target methane, a potent greenhouse gas, with absorption lines matching the emission spectrum of the compact supercontinuum developed within the project.

The team is currently performing an in-depth analysis of the data. However, the first « live » results showed increased levels of methane present in the exhaust fumes of LNG propelled ships. The concentrations matched the ones measured simultaneously by the Explicit team on a detector specifically designed for methane detection.


The team has been very satisfied with the results of the campaign and the behavior of the system. The system has been running as stand-alone onboard the helicopter, while the team on ground could remotely monitor the spectral data and live calculated concentrations through a 4G link.
