## Details

Note that in 2015 it was determined that the stations with codes ACO, AJU, INN, MON and MPA would no longer be taken into consideration when computing the pollution index because they didn't meet the objectives of monitoring air quality, and are no longer included in the index, even if they are still part of the SIMAT (Sistema de Monitoreo Atmosférico de la Ciudad de México). Thus, even if they are located inside a zone, they are not included in the pollution values for that zone.

A transparency request was used to determine the zone to which the municipios of Acolman, Texcoco and Atenco belong.
