Stockholm in Sweden also probably has this. They have several models for meteorological data and air quality is constantly monitored. Theres a public display live daily there. Although if they keep the readings or not I am not sure.
Using meso-scale data you can refine the mesh and calculate the high-definition data that you need with CALMET or another meteo software. You can introduce local meteo data too.
If somebody are interesting on cuasi-real time data, actually we are now analizing data from a monitoring system that belongs to DAVIS stations system on line.
