      Could you please correct the information of your service. I was researching the world's sulfur dioxide emissions today and I got worried. According to your website, there were really violent emissions in Europe due to the volcanic eruption in Iceland. I and also the British media went with the same misinformation. Sulfur dioxide is measured in mg/m3, not mg/m2, as is used on your website. This makes a huge difference. Please correct the information on your website as soon as possible. Here is a link to the media that made the news based on the information on your pages: https://www.dailymail.co.uk/news/article-13777191/Dont-outdoors-morning-Homeowners-given-health-alert-gas-cloud-tipped-skies-UK.html

        The SO2 (sulphur dioxyde) measure in mg/m2 is correct because it is based on satellite observations: It is the quantity of SO2 in a one-square meter base column from ground up to the top of atmosphere (according to ECMWF up to 0.1 hPa level). It is not the ground level concentration as an air quality station can measure it !
        As said in About this data:
        “It is expressed in kg/m2. Forecast are provided from ECMWF IFS. Satellite observations of total column of sulphur dioxide are actively assimilated in the CAMS system and influence subsequent forecasts”
        The data is provided by Copernicus (CAMS)

          Copernicus provides the data in mg/m3, so your data is not correct.

            You clearly see that your map is different from the one from the link I gave here above and different from the one in Windy. The height level of your map is Surface.
            Here is the map similar to the one in Windy.
