Expériences sur des capteurs alternatifs et modèles de prédiction de la pollution atmosphérique

Share: aqicn.org/experiments/










Air Quality monitoring has existed since the 70's, and surprisingly, the equipement used nowdays is still based on the same technology as in the 70's, i.e Beta Attenation Monitors (aka BAM). Almost 50 years later, in 2014, the progress in technology is now allowing us to use new solutions to monitor the Air Quality, with a quality as good as the BAM monitors, but at a much more affordable cost.

The World Air Quality Index project team is involved in understanding, assessing and verifying those new technologies, and this to ensure that they can realiably replace the more traditional BAM-based setups. In this page, you wil find the list of on-going, planned and concluded experiements.

On-going experiments

  • The Dylos Air Particule counter: Can it be used as a substitue of more expensive BAM monitors? A one-year long experiments on trying to correlate Dylos and BAM data in Beijing.
  • Low-cost shinyei and samyoung Sensors: Low cost sensors are used in many of the 'Air Sensor Toys' appearing on Internet. But, can those ultra low-cost sensor provide any good information on air quality? Can any reliable AQI be deducted?

Concluded experiments

  • Haier Air Box: A reverse engineering of the Haier AirBox air quality sensor for the smart home.

Planned experiments

  • The GFS Wind forecast: Is it really accurate? How do actual and predicted data differ?
  • Predicting Air Quality: using the GFS wind forecast to predict Air Pollution flux

À propos de la qualité et de la mesure de la pollution atmosphérique:

A propos des niveaux de qualité de l'air

IQANiveau de pollution de l'air Impact sur la santé
0 - 50 Bon La qualité de l'air est jugée satisfaisante, et la pollution de l'air pose peu ou pas de risque.
51 -100 Modéré Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
101-150 Mauvais pour les groupes sensibles La qualité de l'air est acceptable; Cependant, pour certains polluants, il peut y avoir un problème de santé modérée pour un très petit nombre de personnes qui sont particulièrement sensibles à la pollution de l'air.
151-200 Mauvais Tout le monde peut commencer à ressentir des effets sur la santé; les membres des groupes sensibles peuvent ressentir des effets de santé plus graves.
201-300 Très mauvais Avertissements de santé de conditions d'urgence. Toute la population est plus susceptible d'être affecté.
300+ Dangereux Alerte de santé: tout le monde peut ressentir des effets de santé plus graves.
