Multi Angle Absorption Photometer

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.

Quality and validity

Lineage

Data are daily checked by operators at ISAC-CNR in Bologna and validated year-by-year.

The instrumental set-up is composed by:

- Multi-Angle Aborption Photometer (thermo MAAP 5012).

Minimum Detection Limit (2 minute average): <100 ng/m3 BC < 0.66 M/m Babs

Minimum Detection Limit (10 minute average): < 50 ng/m3 BC < 0.33 M/m Babs

Minimum Detection Limit (30 minute average): < 20 ng/m3 BC < 0.13 M/m Babs

Filter Change: at 20% transmission (approximately 30μg)

Light Source Wavelength: 630 nm (nanometers)

Active Measurement Time: >98%

Air Flow Regulation Deviation: <1% (PID type)

The MAAP readings are corrected for measurement artifacts occurring at high black carbon mass concentration levels by using the methodology suggested by Hyvärinen et al. (2013)
