Ecuador data

This source needs to be explored for compatibility with OpenAQ data format:

http://www.quitoambiente.gob.ec/

Update:

Ecuador source: http://www.quitoambiente.gob.ec/ambiente/index.php/indice-de-calidad-del-aire-2

Seeing, at minimum the following pollutants reported in physical units: SO2, CO, O3,PM2.5, PM10

Data appear hourly, need to be scraped. Stations w/ coordinates are linked on left hand side of the page above: Screen Shot 2020-02-10 at 4 11 47 PM

Note: There are hourly charts for each station/pollutant, but they are very slow to load: http://calidaddelaire.quito.gob.ec/AirVision/Public/Viewer.aspx?GuiFavoriteID=8517bcfc-0a33-4aa3-b7a0-997e140cf1ea

Found another source for this country, but it looks like it is only for one city and has only two stations: https://www.emov.gob.ec/calidad-del-aire/

Looks like for quitoambiante (which is only for Quito, not all of Ecuador btw) we know:

  • [x] Data is ‘raw’ and reported in physical concentrations not in an 'Air Quality Index' or equivalent (e.g. AQI, PSI, API) format, with units (ug/m3 or ppm)

  • [x] Data is at the ‘station-level' with geographic coordinates, not aggregated into a higher (e.g. city) level

  • [x] Data is from measurements averaged between 10 minutes and 24 hours, and we know whether the timestamp is for the beginning or end of the measurement period (? only thing left to figure out, but not a huge deal)

This source looks ready for dev!

For emov need to investigate:

  • [ ] Data is ‘raw’ and reported in physical concentrations not in an 'Air Quality Index' or equivalent (e.g. AQI, PSI, API) format, with units (ug/m3 or ppm)

  • [ ] Data is at the ‘station-level' with geographic coordinates, not aggregated into a higher (e.g. city) level

  • [ ] Data is from measurements averaged between 10 minutes and 24 hours, and we know whether the timestamp is for the beginning or end of the measurement period

It may also be worth investigating if a national-level source is available. emov.gob.ec mentions

Los reportes están basados en requerimiento de la Norma Ecuatoriana de Calidad del Aire, documento tomado del Ministerio del Ambiente del Ecuador

which says the data is based on the national environmental agency's air quality standards (based on my limited Spanish) which could indicate a national monitoring source or other regional sources
