Purpose

Aerosol particles are ubiquitous in the atmosphere. They exert significant effects on the Earth’s climate. First, they absorb and scatter incoming solar radiation (direct radiative forcing). Second, they act as cloud condensation nuclei (CCN), influencing the cloud microphysical and optical properties as well as their life-time and precipitation (indirect effect).

Due to the high variability of the natural as well as the anthropogenic aerosol in the troposphere, the corresponding radiative effects vary highly in time and space.

The latest report from IPCC has shown that atmospheric aerosols represent the largest uncertainty in understanding and giving future predictions of the Earth’s climate. Aerosol number concentration varies greatly in both, time and space.

Meanwhile, the existing in-situ aerosol observation system is patchy with respect to global coverage, very little information are available especially remote environment and in free troposphere.

EBAS is a database hosting observation data of atmospheric chemical composition and physical properties. EBAS hosts data submitted by data originators in support of a number of national and international programs ranging from monitoring activities to research projects. EBAS is developed and operated by the Norwegian Institute for Air Research (NILU).

Statement
The Condensation Particle Counter (TSI model 3772) was installed at ICO-OV in March 2008, calibrated from TSI Laboratories. Once per year the instrument is used for a multi-day intercomparison with the CPC running at the "Nepal Climate Observatory - Pyramid" GAW global station. According to the manufacturer the particle concentration accuracy is ±10%.
