Instrument picture

EOLE is a compact 6-wavelength Raman lidar system, used to perform continuous measurements of suspended aerosol particles in the Planetary Boundary Layer (PBL) and the lower troposphere.

The lidar signals detected at 355, 387, 532, 607 and 1064 nm are used to derive the aerosol backscatter (at 355, 532 and 1064 nm), the extinction (at 355 and 532 nm) coefficient and the Angstrom exponent profiles, while the 407 nm channel was used to derive the water vapor mixing ratio (Mamouri et al., 2007; Papayannis et al., 2012).
