Purpose

The objective of this measurement program is to determine the variability of aerosol scattering coefficient at ICO-OV in relation to air mass origins, and to derive information to describe the most common conditions observed at ICO-OV. In addition, observed values of the scattering coefficient, combined with absorption, can be used to estimate the direct aerosol radiative forcing for the region.

Statement

A M9003 integrating nephelometer (ECOTECH) measures the aerosol scattering coefficient at 525 nm since May 2007. The measured values are automatically adjusted to standard temperature and pressure conditions (0°C; 1000 hPa). Air is sampled trough a TSP inlet, heated in order to evaporate cloud droplets; moreover, an additional heater on the measurement cell eliminates the effects of humidity particle growth on scattering behaviour. A calibration on site with low span gas (filtered air) and high span gas (filtered carbon dioxide) is performed every 3 months. Typically, the instrument is operated with an internal averaging time of 1 minute. M9003 nephelometer participated to the 1st NA4 Aethalometer-Nephelometer Intercomparison (Leipzig, Germany - March 2007) in the framework of EUSAAR project.
