The OPC, manifactured by FAI, permit a - Characterization of the temporal trends of the particulate matter granulometric distribution as a support and integration to information about air quality - Real-time estimation of the PM1, PM2.5, PM10, TPS mass concentration of the airborne particulate matter. Main features - Measurement principle: laser scattering on elliptical mirror - Optical channels: 8 optical channels with thresholds having lower limits [µm]: 0.28, 0.4, 0.5, 0.7, 1.1, 2.0, 3.0, 5.0 - Sampling type: The instrument gives counts per minute, or counts per liter for each optical channel - Dimensional sensitivity: 0.28 µm (50 ± 10% count efficiency)

The integrating nephelometer (model TSI 3563) is a high-sensitivity device capable of measuring the scattering properties of aerosol particles. The nephelometer measures the light scattered by the aerosol and then subtracting light scattered by the walls of the measurement chamber, light scattered by the gas, and electronic noise inherent in the detectors.

At the end of March 2006 a Cimel CE-318 sunphotometer was installed. It provides a characterization of aerosol optical and microphysical properties of the air column above the station. These measurements allow to follow the time evolution of the aerosol optical depth (AOD) at eight wavelengths, plus other properties as single scattering albedo (SSA, fundamental in computing the aerosol effects on solar radiation), particle size distribution (SD, fundamental in assessing the ABC effects on formation and lifetime of water vapor clouds) and refractive index.

25 Halocarbons relevant for climate issues will be analysed in grab samples collected weekly.

An integrating nephelometer (TSI 3563) to determine aerosol back scattering coefficient. These measurements include the aerosol back scattering coefficient at three wavelengths (450, 550 and 700 nm) since 2006.

Sun photometer ( Cimel CE-318) measurements of the direct (collimated) solar radiation provide information to calculate the columnar aerosol optical depth (AOD). AOD can be used to compute columnar water vapor (Precipitable Water) and estimate the aerosol size using the Angstrom parameter relationship. Sunphotometer from March 2006 provides a characterization of aerosol optical and microphysical properties of the air column above the station. It is an automatic sun-tracking and sky radiometer for measuring the aerosol optical depth at 8 wavelengths between 340 and 1020 nm.
