Since year 2000 in EARLINET, the Naples Observation Station includes passive and active remote sensing systems and near surface instruments for the study of environmental subject as air quality, pollutant transport and climatic change.
Thanks to its central location in the Mediterranean basin, the Naples Observation Station is an optimal site for study optical and microphysical properties of different aerosols contributions of natural and anthropogenic origin both related to local and long-range transport phenomena.
The Station is equipped with a multiwavelength Elastic/Raman Lidar device, two sunphotometers (dual polarization and triple mode: sun, sky, lunar) AERONET compliant, two wind lidar investigating the atmospheric range 0.2 - 3.0 km, and many other systems to monitoring fine and ultrafine particles in the atmosphere, to measure in real time the total concentration of particle from 2 nm up to 10 µm as well as their number and mass distribution.
Several systems are transportable and operative h-24 to keep measurements during campaigns in other place. The collocation of different instrument of measurement allows to perform reliable study in the atmosphere as well as at the emission source having also accurate information on atmospheric dynamics.
The integrate measurement approach allows monitoring and evaluating the impact of sensible sources of natural emission, as volcanic eruption, desert dust transport and biomass burning, and anthropogenic pollution sources such as city dump, industries and areas of strategic interest (ports and airports).
