Retrieval of ice-nucleating particle concentrations from lidar observations and comparison with UAV in situ measurements by Dr. Eleni Marinou et al.

An important publication by Dr. Eleni Marinou, associate of NOA, as first author for an original methodology for recovering ice nuclei measurements using remote sensing lidar methods for the implementation of the ERC Consolidator Grant “D-TECT” of National Observatory of Athens, with Research Director Vassilis Amiridis as Scientific responsible.

The ability of remote seinsing ice nuclei is an important development that is expected to optimize medium and global range climate models. The paper presents a new methodology for the retrieval of vertical concentration distribution of ice nuclei using data collected from the advanced lidar system of the PANhellenic GEophysical observatory of Antikythera (PANGEA), the new emblematic infrastructure of NOA. The accuracy of the methodology was assessed with on-site measurements at heights of interest (up to 3 km from sea level) collected with unmanned aerial vehicles of Cyprus Institute during the pan-European INUIT-BACCHUS-ACTRIS experiment with multiple participations of collaboratoring institutes such as the Cyprus Institute, TROPOS Institute, Goethe University Frankfurt and of course NOA. The work highlighted the possibility of applying this method to satellite data. This perspective paves the way for the creation of a global database of three-dimensional particle distribution related to the creation of ice crystals within the clouds. Professor Athanasios Nenes, from EPFL Atmospheric Research Laboratory in Switzerland and partner of FORTH, also made a valuable contribution for this paper.
