In the framework of the SusKat (Sustainable Atmosphere for the Kathmandu Valley), ABC-UNEP and NextData Projects, CNR-ISAC and URT Ev-K2-CNR participated in the setting-up of the Kathmandu (Pakanajol) monitoring station. In particular, the station is equipped with: • meteorological sensors; • global pyranometer for downward solar short-wave radiation; • surface ozone analyzer; • optical particle counter for aerosol size distribution from 0.3 to 10 micron; • on-line PM1/PM10 analyser ; • multi-angle absorption photometer for equivalent black carbon mass measurement.

The Portable Aethalometer Model AE42 manufactered by Magee measures light absorption by suspended aerosol particles at two wavelengths: 880 nm (IR), quantitative for the mass of ‘Black’ Carbon; and 370 nm (UV), indicating aromatic organic compounds. The instrument’s analytical performance is identical to the Rack Mount Aethalometer Model AE22, but it is constructed in a small portable case with an internal battery providing several hours of mobile operation. The Portable Aethalometer can also be operated from an AC transformer or by cables from an external battery or automobile power outlet. This instrument is widely used for studying indoor air quality, and for the mobile mapping of the air quality impacts of localized sources. The Portable Aethalometer may also be supplied with 7 wavelength light sources upon request.

The Model 205 Ozone Monitor makes use of two detection cells to improve precision, baseline stability and response time. In the Dual Beam instrument, UV light intensity measurements Io (ozone-scrubbed air) and I (unscrubbed air) are made simultaneously. Combined with other improvements, this made it possible to reduce the time between ozone measurements to 2 seconds, making our instrument the fastest UV-based ozone monitor on the market, while still retaining the small size, weight and power requirements of our popular Model 202 Ozone Monitor.
