Hi. In your interactive map providing near-real-time information about air pollution (<a href="http://www.eea.europa.eu/themes/air/air-quality-index" rel="nofollow">http://www.eea.europa.eu/themes/air/air-quality-index</a>) the Italian monitoring stations are always grey (&quot;No data&quot;). As far as I know, the Italian Institute ISPRA will start sending the data in few weeks. Nevertheless, I wonder if this will be enough to calculate the Air Quality Index for most of the Italian monitoring stations. As explained in your webpage, &quot;the index is calculated for those stations which measure at least the three pollutants NO2, O3 and PM&quot; and &quot;PM10 and PM2.5 values are based on 24-hour running means&quot;. Therefore, if I understood correctly, no AQI is calculated for the stations which do not measure PM on hourly basis. Unfortunately, in most of the Italian regions, almost all measures of PM are daily concentrations, not hourly. So will Italy continue to be gray?
