good morning. good morning and hope all is well.
following the India Together piece and the AQI related articles in the press, we had some questions on what to do, if the data from the stations is not reliable or enough. The following is an effort to show the flow of information to AQI. http://urbanemissions.blogspot.in/2015/04/infographic-reporting-air-quality-index.html This is not meant to give a scientific background on the subject, but to show how the information can flow with and without monitors in place. There is more in each of the steps (+'s and -'s), but thinking about it is a start. The bottom-up approach heavily relies on GIS databases.
