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.

Information can be accessed in different portals. Most information can is gathered int the National Institute of Ecology (https://sinaica.ine.gob.mx) though machine readable files commonly do not follow a database layout. Data is clustered at a state level and divided in different time-lapse data clusters. Most files are accessible in: https://www.inecc.gob.mx/calaire-presentacion/546-calaire-indicadores The Ministry of Environment's porta contains similar information: https://app1.semarnat.gob.mx/dgeia/clave_2010/clave/indicadores/ibi_apps/ind_clave_05.html https://app1.semarnat.gob.mx/dgeia/clave_2010/clave/indicadores/ibi_apps/ind_clave_06.html https://app1.semarnat.gob.mx/dgeia/clave_2010/clave/indicadores/ibi_apps/ind_clave_08.html Also, data is also identified under research center's web sites, such as Mexico's National Autonomous University: https://www.atmosfera.unam.mx/procca/Ozono.php Furthermore, SEMARNAT's Pollution Transfer and Emissions registry (RETC) contains a national database of air, water, ground and underground contains record of pollution sources and environmental assessments. RETC's landing page can be accesed here: https://www.semarnat.gob.mx/temas/gestionambiental/calidaddelaire/Paginas/retc.aspx and data (not in bulk) accessed here: https://app1.semarnat.gob.mx/retc/retc/index.php No license information found, which means it's not an open license.

Found bulk data for air measurements here but it's not timely (until end of 2008): https://www2.inecc.gob.mx/dgicurg/calaire/tend/horarias/concentra.php
