        <gco:CharacterString>V souladu s přílohou 2 Vyhlášky 106/2025 Sb., kterou se provádí některá ustanovení zákona o veřejné hydrometeorologické službě, ČHMÚ zpřístupňuje aktuální operativní (neverifikované) hodinové údaje indexu kvality ovzduší. Index kvality ovzduší (IKO) poskytuje souhrnnou informaci o kvalitě ovzduší na konkrétní měřicí stanici. Tento index byl navržen Úsekem kvality ovzduší Českého hydrometeorologického ústavu (ČHMÚ) ve spolupráci se Státním zdravotním ústavem (SZÚ). Konkrétní rady a doporučení SZÚ zaměřené na ochranu lidského zdraví  jsou uvedeny zde www.chmi.cz/files/portal/docs/uoco/web_generator/d_szu.pdf. Pravidla pro stanovení IKO a jeho výpočet je uveden na https://www.chmi.cz/files/portal/docs/uoco/web_generator/iko3h_cz.pdf.

Informace pro veřejnost prostřednictvím jednoduchého a srozumitelného ukazatele, který komplexně charakterizuje kvalitu ovzduší s ohledem na zdravotně podložená doporučení Světové zdravotnické organizace.</gco:CharacterString>

The Air Quality Index (IKO) provides a summary of air quality at a specific monitoring station. This index was developed by the Air Quality Division of the Czech Hydrometeorological Institute (ČHMÚ) in collaboration with the National Institute of Public Health (SZÚ). Specific advice and recommendations from SZÚ aimed at protecting human health can be found here: www.chmi.cz/files/portal/docs/uoco/web_generator/d_szu.pdf. The rules for determining the IKO and its calculation are available at https://www.chmi.cz/files/portal/docs/uoco/web_generator/iko3h_cz.pdf.

Information for the public provided through a simple and comprehensible indicator that comprehensively reflects air quality, considering health-based recommendations from the World Health Organization.</gmd:LocalisedCharacterString>
