Submicron Aerosol Composition and Source Contribution across the Kathmandu Valley, Nepal, in Winter
{{output}}
The Kathmandu valley experiences an average wintertime PM1 concentration of ∼100 μg m-3 and daily peaks over 200 μg m-3. We present ambient nonrefractory PM1 chemical composition, and concentration measured by a mini aerosol mass spectrometer (mAMS) sequent... ...
