| findable_steps | The official site has a prominent position in search results. Hourly data are easy to find, but for daily or monthly summaries, i had to dig through the site. I have ask about VOCs as it is hidden in a pile of links with stats and reports. | |

| characteristics | Particulate matter (PM), Sulphur oxides (SOx), Nitrogen oxides (NOx), Carbon monoxide (CO), Ozone, Available per air monitoring station/zone | Pollutants except VOCs are available, but not for every measuring station (see links in B2.2). I asked a responsible clerk and was told that for some towns, thresholds are not being exceeded and therefore the coverage of measurements was reduced few years ago. VOCs are published on a yearly basis (data per months). |
| location | https://portal.chmi.cz/files/portal/docs/uoco/web_genera - Daily measurements for a measuring station, https://portal.chmi.cz/files/portal/docs/uoco/web_genera - Hourly data for all measuring stations, https://portal.chmi.cz/files/portal/docs/uoco/isko/tab_r - VOCs are published yearly for just 2 stations, https://portal.chmi.cz/files/portal/docs/uoco/web_genera - Daily data form another station to show that some pollutants, such as SO2, are measured only for selected locations. | After a discussion, i decided to take the 24hour measurements as a baseline. https://discuss.okfn.org/t/air-pollution-hourly-data-in-open-formats-daily-summary-not/4100 |
