Real Time AAQ Monitoring System (Continuous Ambient Air Quality Monitoring)
The air quality monitoring data is generated from Continuous ambient air quality monitoring station (CAAQMS) at National Environmental Engineering Research Institute(NEERI), Nagpur, to study the trends of concentration of particulate matter (PM) and gases air pollutants in ambient air. The ambient air quality monitoring network involves measurement of various number of air pollutants. A variety of methods exist to measure particulate matter as well as gaseous pollutants in the air.
Method of measure air pollutants :
| Sr.no. | Name | Model No. | Methods |
|---|---|---|---|
| 1 | SO2 analyzer | AF22M-1895 | Fluorescent in ultraviolet technique |
| 2 | NOx Analyzer | AC32M-2214 | Chemiluminescent |
| 3 | CO analyzer | 12M-1474 | Infrared absorption |
| 4 | VOC analyzer | 72M-73 | Gas chromatography (GC) and photo-ionization detector (PID) |
| 5 | PM2.5 analyzer | MP101M - 3759 | Beta-attenuation |
| 6 | PM10 analyzer | MP101M - 3760 | Beta-attenuation |
| 7 | O3 analyzer | O342M - 1392 | UV photometry |
