I've found out a programmatic way to eliminate the hassle with using the CPCBs UI. It's true that the averages across multiple frequencies do not match at times. I'm working on a client that returns a dataframe for a given date, range, sampling frequency and station. Will push the code over the weekend and post an update here. There's a simple interface that I'm also writing alongside which will easily let us understand what are different stations and parameters available in a particular station. 1. https://love-the-air.herokuapp.com/states lists the states which have stations 2. http://love-the-air.herokuapp.com/state/< <http://love-the-air.herokuapp.com/Assam>state> eg., http://love-the-air.herokuapp.com/state/Assam returns a list of cities that have active stations within that state. 3. https://love-the-air.herokuapp.com/city/< <https://love-the-air.herokuapp.com/city/Guwahati>city> eg., https://love-the-air.herokuapp.com/city/Guwahati returns a list of available stations in that city. 4. https://love-the-air.herokuapp.com/station/< <https://love-the-air.herokuapp.com/station/site_5073>station_id> eg., https://love-the-air.herokuapp.com/station/site_5073 returns a list of parameters that are specific to that particular station. The code is available here https://github.com/sakethramanujam/love-the-air Thanks, Saketh. -- Datameet is a community of Data Science enthusiasts in India.
