Here is a small contribution form the World Air Quality Index project to the ASMC - ASEAN Specialised Meteorological Centre (asmc.asean.org) during this heavy period of Haze in South Asia.

We have updated our tile map webservice based on the PM10 raw concentration color scale defined on asmc-haze-air-quality page. This service can be used to overlay the current PM10 concentration on any existing map (eg google map - see example below).


The color codes on this map correspond to the ASEAN PM10 color scale.

Note: For all countries except Malaysia and Brunei, the data is based on the 24-hour PM10 average. For Malaysia and Brunei, the data is based on the 24 hours[1] PSI average which is most likely caused by PM10 in this period of haze.
To add the tile overlay to a google map, you jsut need to add the following code: (You can also refer to this article for a full explanation)

<script>  
var  waqiMapOverlay  =  new  google.maps.ImageMapType({  
            getTileUrl:  function(coord,  zoom)  {  
                      return  'http://tiles.aqicn.org/tiles/asean-pm10/'  +  zoom  +  "/"  +  coord.x  +  "/"  +  coord.y  +  ".png";  
            },  
            name:  "Asean  PM10  concentration",  
  });  
  
googleMap.overlayMapTypes.insertAt(0,waqiMapOverlay);  
</script>

    About the Air Quality Levels

    AQIAir Pollution LevelHealth ImplicationsCautionary Statement (for PM2.5)
    0 - 50GoodAir quality is considered satisfactory, and air pollution poses little or no riskNone
    51 -100ModerateAir 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.Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
    101-150Unhealthy for Sensitive GroupsMembers of sensitive groups may experience health effects. The general public is not likely to be affected.Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
    151-200UnhealthyEveryone may begin to experience health effects; members of sensitive groups may experience more serious health effectsActive children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion
    201-300Very UnhealthyHealth warnings of emergency conditions. The entire population is more likely to be affected.Active children and adults, and people with respiratory disease, such as asthma, should avoid all outdoor exertion; everyone else, especially children, should limit outdoor exertion.
    300+HazardousHealth alert: everyone may experience more serious health effectsEveryone should avoid all outdoor exertion
