Concept information
Preferred term
BAPMON
Definition
- With a view to documenting the long term changes in composition of trace species of the atmosphere as a result of changing land use pattern, WMO had commissioned a global programme called Background Air Pollution Monitoring Network (BAPMoN) which is now a part of the Global Atmospheric Watch (GAW) Programme. India had set up 10 such BAPMon stations. At these stations, rain water samples are collected every month and these are sent to the Central Chemical Laboratory at Pune for complete chemical analysis. Acidity of rain and mineral deposition is determined from these. Atmospheric turbidity which indicates the columnar aerosol load of the atmosphere, is also measured at these stations using sunphotmeters. These data are important for identifying the current levels of pollution as well as for study of the long term trends in the concentration of trace constituents of the atmosphere which may affect the environment and induce a climate change. To study the impact of industrialisation, urbanisation and terrain modification on micro-climatological features of urban areas, urban climatological studies are carried out in metropolitan cities.
