RIVM, air quality

From Intamap

[RIVM] has a web page that shows real-time interpolations of air quality variables, see here. The initial link gives an overview of four indicators; the qualitative legend shows values ranging from small (geen/gering) to moderate (matig) to severe (ernstig) pollution. Clicking one of the maps gives the detailed maps with legends in concentration values. Clicking "volgend uur" jumps a week back, presumably to the first of the hourly maps served.

Clicking on "histogram", and then clicking a monitoring station gives graphs with the time series, supported by threshold values (severeness, expressed by colours green-yellow-red).

The site is in Dutch but has a number of interesting features. "Verwachting" gives predictions for the next day, for each of the monitoring stations (map with points, and table).
