Observed Sulfate Aerosol Concentrations In Different Chinese Cities.pdf

Data is presented for two types of aerosols: sulfate aerosols and nitrate aerosols, with a focus on PM2.5 (particulate matter less than 2.5 micrometers in diameter) where available.

Sulfate Aerosol Concentrations:

| Location | Period | Concentration (µg m-3) | Reference | Notes on Measurements |
|---|---|---|---|---|
| Beijing | Aug 2001 - Sep 2002 (Summer) | 13.43 | Duan et al. (2006) | PM2.5 collected weekly on a 3-m tall building |
| Nanjing | Sep 2001 (Autumn) | 8.79 | Wang et al. (2002) | PM2.5 collected daily for 12 hours on a two-story building |
| ... (Other locations and periods listed similarly)| ... | ... | ... | ... |
| Dalian | 2006-2007 (Spring) | 11.68 | Zhang et al. (2012) | Rural stations above ground level; PM2.5 collected weekly |

Nitrate Aerosol Concentrations:

| Location | Period | Concentration (µg m-3) | Reference | Notes on Measurements |
|---|---|---|---|---|
| Beijing | Jul 1999 - Sep 2000 (Summer) | 4.59 | He et al. (2001) | PM2.5 collected weekly on a 3-m tall building |

Additional Notes:

Concentrations are presented as observed values unless otherwise noted.
Sampling methods varied across locations and time periods, including rooftop samplers at different heights above ground level and integrated weekly or daily collections.
