Purpose

Ozone (O3) is one of the most important gases involved in atmospheric photochemical processes. Being the precursor of oxidizing substances like OH and NO3, O3 is one of the key agents determining the oxidation capacity of the troposphere. Due to its chemical properties, O3 is also a dangerous secondary pollutant in the lower troposphere. Moreover, there has been great interest in the influence of tropospheric O3 on climate over the last decades, because of its central role in the regional radiative budget of the atmosphere. For understanding the factors influencing the tropospheric O3 budget, continuous monitoring in background conditions (i.e., conditions not directly influenced by anthropogenic activities, like mountain areas) represents a fundamental activity.

Statement

The air is sampled by a 2m long heated intake at 7 m height above the ground.

The air intake is composed by an external (outside building) steel pipe (internally covered by Teflon) and the internal (inside building) Pyrex pipe.

A Teflon sampling line (lenght 1. connects the air intake with analysers.

The UV photometer analyser (1108 W/GEN #136) is calibrated by the laboratory transfer standard (Dasibi 1008 PC #6506) twice a year.

On October 2006, the laboratory transfer standard (Dasibi 1008 PC #6506) has been compared with IMGC-O3SRP at the National Institute of Metrological Research (INRIM) with primary standard and treaceability chain in Italy.

On June 2008, the laboratory transfer standard (Dasibi 1008 PC #6506) has

been compared with SRP#15 at the World Calibration Centre for surface O3 (WCC-EMPA).

The UV photometer analyser (1108 W/GEN #136) was also checked and calibrated at the DASIBI ITALIA company in November 1996, December 1997, April 2001, November 2001,July 2005.

The laboratory transfer standard (Dasibi 1008 PC #6506) was also checked and calibrated and at the DASIBI ITALIA company in July 1996, November 1999, August 2005, August 2007.

Processing Row data from monitoring device are acquired every minute and processed to half-hour mean values (by averaging 10 minutes mean values in the period 1996-2001).
