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

On June 24th 2020 FLAIR Consortium successfully performed first flying test in Beromünster, Switzerland. Collaborative research journey started in 2016 led to its first testing flight to validate FLAIR system functionality. For the initial flight was used Zeppelin platform and test was controlled by scientists from EMPA and CSEM. Test successfully measured elevated methane concentration when flying above the controlled release installation. At the moment FLAIR Consortium eval

Senseair has built and trimmed a long path length Multipass cell with a light distance of almost 18 meters. This equipment has been shipped to the researchers at CSEM in Neuchatel, Switzerland for verification and test. The next step in the development of optics is to replace the mirrors with new ones having higher reflectivity in the mid-IR spectral range. Moreover, Senseair will arrange for convenient interface with the laser beam input, and beam exit towards the spectromet

CSEM in Switzerland is currently designing and implementing an alternative detector prototype. The initial spectrometer with the VIPA is showing adequate resolution to resolve the fine structure of N2O gas spectral footprint. However, it appeared that the detection limit is currently 2 orders of magnitude too high to measure diluted samples as requested in the FLAIR project. The revised design promises reduced optical losses and larger power per spectral unit achieved through

We are happy to release first movie about the project! Thanks to our great Consortium members for taking active part and participation in shooting: Swiss Federal Laboratories for Materials Science and Technology (EMPA), Tekever Autonomous Systems, NKT Photonics A/S, New Infrared Technologies (NIT), Technical University of Denmark (Department of Photonics Engineering), Radboud University (The research group in the Institute of Molecules and Materials), SenseAir AB and Swiss Ce
