Aggregate data about the emission of air pollutants especially those potentially harmful to human health (although it is not a requirement to include information on greenhouse gas emissions). Aggregate means national-level or available for at least three major cities. In order to satisfy the minimum requirements for this category, data must be available for the following pollutants and meet the following minimum criteria:

• Particulate matter (PM) Levels
• Sulphur oxides (SOx)
• Nitrogen oxides (NOx)
• Volatile organic compounds (VOCs)
• Carbon monoxide (CO)
• Updated on at least once a week.
• Measured either at a national level by regions or at leasts in 3 big cities.

Comments

Air polution monitoring data is published on a monthly basis. Queries can be made for custom time periods. Measurements include the maximum concentration of carbon dioxide, nitrogen dioxide, ozone and particulate matter.

Air quality measurements are taken by automatic DOAS OPSIS stations ensuring continuous registration of polluting substances.
