Monitoring Stations

There are three monitoring stations belonging to the Institute of Atmospheric Pollution Research:

%22A. Liberti%22 Monitoring Station
EMEP

CNR-IIA participate to EMEP program that is based on three main activities: emission data capture, assessment of air quality and wet deposition, development and application of pollutant transport and deposition models.

The present structure of EMEP network for air quality and wet deposition assessment is based on several participation levels:

  • Level 1 (mandatory parameters)
  • Level 2 (additional parameters)
  • Level 3 (super-sites research oriented)

“A. Liberti” Monitoring station  Measurement program:

  • Lev1:  NO2, O3  by means of continuous analyzers
  • Lev1:  Cl-, NO3- SO4=, Na+, NH4+, K+, Mg++, Ca++, ph, wet deposition conductivity
  • Lev1:  PM10, PM2.5 by means of continuous analyzers
  • Lev1:  Cd, Pb, Cu, Zn, As, Cr, Ni in wet deposition
  • Liv2: HNO3, SO2, NH3 mediante linee di diffusione (denuders)
  • Lev2: HNO3, SO2, NH3 by means of diffusion denuders
  • Lev2:   NO3- SO4=, Cl-, Na+, NH4+, K+, Mg++, Ca++, Si, EC/OC in PM10

EMEP Program Equipment

  • PM Sampler – ADAM C (PM 2,5)
  • PM Sampler- Hydra (PM10)
  • PM Sampler – SWAM (PM10)
  • Stability Monitor – PM10 TSP (PBL)
  • NOx Analizer – SARTEC 200A
  • O3 Analizer – API 400A
  • Meteo Station – LSI/LASTEM

 Station Instrumental equipment

The equipment comprehend PM10/PM2,5 samplers, gas phase mercury analizer, a station for nano-particles evaluation, an area equipped for monitoring campaigns, a metereological station.

Equipded area and ADS7 samplers detail:

  • PM Sampler – Hydra (PM10/PM2.5)
  • 2 Sequential sample TECORA Skypost PM
  • Gas phase mercury analizer TEKRAN
  • Scanning Mobility Particle Sizer – SMPS equipped with a double column DMA (4-600nm)
  • 2 – Condensation Particle Counter – CPC
  • Nanometer Aerosol Sampler – NAS
  • Meteo station – T, RH, p, wind speed and direction, solar radiation, wet deposition
Aeronet Station
High Altitude Monitoring Station

The hight altitude station (1379m asl) is situated near the village of Longobucco in the Sila Massif between the Thyrrenian and Ionian seas (Lat 39° 23′ 39,05 ” Lon 16° 36′ 48,74″). It is a fenced in Portacabin type structure of roughly 26 sq. metres. The fence is necessary as the surrounding area is used as seasonal pasture. There is enough space for a number of fixed analytical lines as well as for non-permanent instrumentation, for example for intercomparisons or for intensive measurement campaigns.

The station also has a data acquisition system which allows data to be transmitted to the Rende section in real time, as well as a video surveillance system.

Measurement programme

The table below shows the measurements, the methods used and their frequency and their relationship to the three levels of the EMEP programme. The measurement program at the marine station as  well as supporting EMEP also supports the Global Atmospheric Watch (GAW), and the IGBP core projects SOLAS and IGAC.
