چکیده
As we replied above, the aerosol mass absorption efficiency (Qa) is also estimated from PM10 measurements (see Line 5-6, Page 7 of Section. 3.3). We also will clarify this in the revised manuscript. Many previous studies also showed Qa for BC from lab-generated aerosols, ambient aerosols, diesel engines and theoretical calculations (e.g., Mie scattering theory). Bond and Bergstrom (2006) reviewed all these published papers and suggested Qa of 7.5 m2/g for fresh BC. This value has been popularly used for simulating BC’s radiative effect. Therefore we cited Qa of Bond and Bergstrom (2006) to explain why we observed higher Qa at Kathmandu.

Interactive comment on “Source apportionment of NMVOCs in the Kathmandu Valley during the SusKat-ABC international field campaign using positive matrix factorization” by
The manuscript shows results of a source apportionment study of NMVOCs measured by PTR-TOF-MS in the Kathmandu Valley in Nepal during winter 2013. Positive matrix factorization analysis was conducted to identify possible emission sources for 37 m/z measured by PTR-MS. The sources were identified from the chemical fingerprint of each PMF factor and their diurnal profiles. Conditional probability...

A positive matrix factorization model (US EPA PMF version 5.0) was applied for the source apportionment of the dataset of 37 NMVOCs measured over a period of 19 December 2012 – 30 January 2013 during the SusKat-ABC international air pollution measurement campaign using a Proton Transfer Reaction Time of Flight Mass Spectrometer in the Kathmandu Valley. In all, eight source categories were ident...
