      Hi Windy!
      thank you and congratulations for your exellent work!

      I found a discrepancy (a bug?) in Windy in temporal resolution for some station data:
      Windy shows hourly resolution (problem)
      while PM10 & PM2.5 data are published without hourly resolution , daily only @ Midnight

      --> Air quality index seems good, but it's poor!

      Here details:

      • official station Milano Pascal Città Studi:
        https://www.arpalombardia.it/temi-ambientali/aria/stazioni-fisse/dettaglio-stazioni-fisse/?zona=1&citta=451&stazione=705
        data are published but without hourly resolution for PM10 & PM2.5 , daily only @ Midnight -
        hourly data for NOx, SO2, O3, Benzene
