National Physical Laboratory has established an atmospheric monitoring station in the campus of the Institute of Himalayan Bioresource Technology at Palampur, Himachal Pradesh at 1391m for generating the base data for atmospheric trace species and properties to serve as reference.
The aim is comparison of polluted atmosphere in India. At this station, NPL has installed state-of-the-art air monitoring system, GHG measurement system and Raman Lidar.
Numerous parameters like CO, NO, NO2, ammonia, sulphur dioxide, ozone, particulate matter, HC and BC besides carbon dioxide and methane are being monitored at the station.
On account of Palampur’s pristine air, and the capability of the new monitoring station for detection of small amounts of pollutants, the impact of faraway pollution sources can be measured precisely.
The data taken at this station during past one year shows that the pollution levels are far below the limits of National Ambient Air Quality Standards (NAAQS).
A new station has the experimental facilities to investigate the aerosol/cloud interactions, and such investigations would be helpful in generating a better understanding of the Earth’s climate system.
The data generated by pristine CAAQMS station at Palampur will act as background data for the measured pollution at various cities in the country.
The generated background data will be shared with different pollution control boards and agencies in the country so that the more precise pollution mapping traceable to standard values can be done.
This would assist policy decisions for the abatement of air pollutants.About the CAAQMS Station
- In India, air quality parameters are mostly measured in industrial and residential areas.
- The NPL’s station will also serve as a base station for inter-comparison of air quality monitoring equipment.
- The pristine CAAQMS station houses calibrated state-of-the-art-equipment for the continuous measurements of ambient and greenhouse gases (CO, NO, NO2, NH3, SO2, O3, PM1, PM2.5, PM10, hydrocarbons, black-carbon, CO2 & CH4), and weather parameters.
