{"stac_version":"0.9.0","id":"ch.bafu.luftreinhaltung-schwefeldioxid","title":"Air pollution by sulfur dioxide","description":"Higher concentrations of sulfur dioxide (SO₂) can have especially negative effects on the respiratory tract; asthmatics and people with chronic respiratory diseases are particularly at risk. SO₂ is toxic to plants. It is also an important precursor for the formation of acid precipitation and secondary particulate matter. Sulphur dioxide emissions are produced by the combustion of sulfur-containing fuels and by some industrial processes. The time series shows the modeled maps of the annual mean values since 1980 in a 200 m grid, and in a 100 m grid from 2020. The SO₂ concentrations may deviate locally from the modeled data. Individual pixels should not be used to evaluate individual locations. The annual limit for SO₂ set in the Ordinance on Air Pollution Control is 30 µg/m³.","summaries":{"proj:epsg":[2056]},"extent":{"spatial":{"bbox":[[5.96,45.82,10.49,47.81]]},"temporal":{"interval":[["1980-12-31T00:00:00Z","2024-12-31T00:00:00Z"]]}},"providers":[{"name":"Federal Office for the Environment FOEN","roles":["producer","licensor"],"url":"https://www.bafu.admin.ch/bafu/en/home.html"}],"license":"proprietary","created":"2025-02-28T09:44:34.738437Z","updated":"2026-03-19T09:43:19.474578Z","links":[{"rel":"self","href":"https://data.geo.admin.ch/api/stac/v0.9/collections/ch.bafu.luftreinhaltung-schwefeldioxid"},{"rel":"root","href":"https://data.geo.admin.ch/api/stac/v0.9/"},{"rel":"parent","href":"https://data.geo.admin.ch/api/stac/v0.9/"},{"rel":"items","href":"https://data.geo.admin.ch/api/stac/v0.9/collections/ch.bafu.luftreinhaltung-schwefeldioxid/items"},{"rel":"alternate","title":"STAC Browser","type":"text/html","href":"https://data.geo.admin.ch/browser/index.html#/collections/ch.bafu.luftreinhaltung-schwefeldioxid"},{"href":"https://www.geocat.ch/geonetwork/srv/eng/catalog.search#/metadata/446fdb6e-5768-4549-8f58-187ca82e8dea","rel":"describedby","title":"Metadata"},{"href":"https://www.bafu.admin.ch/dam/bafu/de/dokumente/luft/fachinfo-daten/karten_der_luftbelastunginderschweiz-dokumentation.pdf.download.pdf/karten_der_luftbelastunginderschweiz-dokumentation.pdf","rel":"about","title":"Further information"}],"crs":["http://www.opengis.net/def/crs/OGC/1.3/CRS84"],"itemType":"Feature","assets":{"luftreinhaltung-schwefeldioxid.zip":{"title":"Additional files","type":"application/zip","href":"https://data.geo.admin.ch/ch.bafu.luftreinhaltung-schwefeldioxid/luftreinhaltung-schwefeldioxid.zip","created":"2025-03-04T15:21:10.125490Z","updated":"2025-03-04T15:21:09.534274Z","checksum:multihash":"1220c3ff6fcad289febbcec0b75b9e6350151116a0bdabbaa78cb6685398f9804141"}}}
