Bangalore, Among World's Top Polluted Megacities

Apart from unveiling reliable data about the pollution trends in the world, Prof. Alpert speculates that this method of monitoring can also bring out the countries responsible for their emissions and which will make them incorporate more environmental friendly practices.

The research team is working on developing methods to separate the pollution caused by natural destructions from the ones caused by humans for more accurate data.

Prof Alpert told that recording accurate measurement of pollution is not easy job. The monitoring stations on the ground don’t always provide the most precise picture. The location of the monitoring stations play an important role in this, where some cities position their stations in urban centers whereas others construct it on city borders, which leads to a discrepancy of collected records.

The other reason that makes it difficult to analyze pollution is the standardized approach to smog; also the unreliable data received from the monitoring station does create commotion.

However the aim of international treaties to reduce pollution could rely on the current method of measuring pollution. Prof Alpert suggested that the cities which have successfully shown decrease in the pollution levels should be seen as an example to follow.
