The new site of LRSU Laboratory is on air.
LRSU was recently admitted as Associated Partner of the ESFRI (European Strategy Forum on Research Infrastructure) Roadmap for world-class Research Infrastructure, as part of the ACTRIS 2 Project (EU Horizon 2020).
Prof. Alex PAPAYANNIS was elected President of the ICLAS (International Coordination group for Laser Atmospheric Studies) (2015-2021)

EOLE is a compact 8-wavelength Raman lidar system, used to perform continuous measurements of suspended aerosol particles, and water vapor in the Planetary Boundary Layer (PBL) and the free troposphere (0.3-15 km).
The lidar signals detected by a 300 mm telescope at 355, 387, 532, 607 and 1064 nm are used to derive the aerosol backscatter (at 355, 532 and 1064 nm), extinction (at 355 and 532 nm) coefficient and Angstrom exponent profiles, while the 407 nm channel is used to derive the vertical profile of the water vapor mixing ratio (Mamouri et al., 2007; Papayannis et al., 2012). A 200 mm telescope is used to detect the cross- and co-polarized lidar signals at 355 nm, to retrieve the vertical profile of the linear particle depolarization ratio at 355 nm. The calibration technique applied for the aerosol depolarization measurements is the ±45o calibration method, introduced by Freudenthaler et al. (2009).
