Askole Particle number

A new embedded-transportable monitoring system (SHARE-BOX), specifically designed to perform atmospheric observations in remote regions, has been deployed at Askole from 20th August to 10th November 2012.

The system was equipped with a ), condensation particle counter (CPC - TSI 3010) able to provide total number concentration for particles with diameters 15 nm < Dp < 3 micron.

Quality and validity

Lineage

The embedded station used during the Askole field campaign has been tested during a 10-day period at the Monte Cimone WMO/GAW Global Station (CMN; 44.10N, 10.70E; 2165 m a.s.l.), in January 2011. At CMN, the routine measurement programmes for the continuous determination of ozone mixing ratio are performed in the framework WMO/GAW programme, for which data quality is well assessed (Zellweger et al., 2012). During this test, in the case of RH<100%, the maximum difference between the observations at CMN and those performed by the embedded system did not exceed 20% for particle number.

Sampling of aerosol and gases is performed through a common stainless-steel inlet working at approximately 2 l/min. The inlet efficiency at low wind-speed (3 m/s) is calculated to be close to 80% for 1µm - particle. For higher wind-speed, lower efficiency is expected due to inlet geometry and flow-rate. If we assume that particles with diameters Dp <150 nm account for the majority of particle number concentration, as observed at the high altitude site of the Nepal Climate Observatory – Pyramid (NCO-P, 5079 m asl, Nepal; see Sellegri et al., 2010), potential loss of large particle should not affect Np in a significant way.
