Hi,

Environmental governance in India has been undergoing a major
overhaul. In order to track release of pollutants through air
emissions and effluent discharge from industries with high pollution
potential, Central Pollution Control Board (CPCB) introduced online
Continuous Emission Monitoring Systems (OCEMS), a real-time air and
water pollution monitoring system vide its letter dated 05.02.2014.
Continuous monitoring of emissions and effluents from the discharge
points of industrial units. The analysers are installed on stacks or
chimneys and at the outlets of Effluent Treatment Plants and Sewage
Treatment Plants. The analysers continuously generate data at
intervals of one second to few minutes. Read More

Please do share your valuable comments and suggestions.

Warm regards,

All models are wrong: some models are useful
– Noel de Nevers in his book ‘Air Pollution Control Engineering’.

It's true whether you believe in it or not. Ideally, the perfect air pollutant concentration model would allow us to predict the concentrations that would result from any specified set of pollutant emissions, for any specified meteorological conditions, at any location, for any time period, with total confidence in our prediction.

However, the best currently available models are far from this ideal. In fact, all these models are simplifications of a reality, leading to my belief too that all atmospheric models are wrong but some of them are useful for the qualitative study only.
