we are about to present you a new map with statistic for CZ/SK/AU. The data used is not validated data (mean not cleared if damaged/impacted by a close pollution source) directly from json. Thank you CHMI and idea-envi.cz for their JSON API! You already may see and grab the collected data here: https://pollutants.eu/map/index2.php. Stay tuned, very soon the interface will be upgraded with new smooth chart, more functionality pending! More than 250 stations is already tracking!
*upd Charts have been updated, the old statistic is avaliable here: https://pollutants.eu/map/index.php
