It would be great to have statistics for the last 12 months, with one chart for each month that would show average for a individual hour like in existing charts.
It's very useful when you are thinking to move somewhere on a longer period.
Thanks for doing great job!
I agree totally. I want to have a ranked list of the cleanest cities/countries. I would take this into account when deciding where to live long term or bring up kids, etc. Thanks!
