The latest version 3.2 of the World Air Quality Index project Android application has just been released, and comes with few new cool features: The embedded map which will let you navigate through the world air monitoring station directly from the app and the wind and temperature forecast tab which gives you the coming 3 days forecast. We have also been working on refreshing the visual and updating settings to support, for instance, Fahrenheit temperature display.

You can get the app from the google store, or directly download the signed apk from our website, in case you do not have access the Android app store.

Features Summary:

Navigation:

  • The application is now using tabs for better navigation. In order to switch between the tabs, you just need to swipe left and right.

Current Conditions:

  • Current Air Quality Index and weather condition, including temperature, wind speed and wind direction, as well as weather forecast for the day.
  • 24 hours graphs for all available pollutants (PM2.5, PM10, Ozone, but also Carbone Monoxide, Nitrogen Dioxide and Sulfur Dioxide) as well as meteorological data (temperature, humidity and wind) displayed in the main tab.
  • The AQI information for the surrounding stations displayed in the "nearest stations" tab.

Notifications:

  • Notifications, which will warn you whenever the AQI gets too high, can be enabled from the settings tab, (option "Notify AQI updates in the status bar").
  • You can also define the threshold for the notification. By default, it is set as 150, but sensitive person might want to set it as 100 or below.
  • Note that this feature is only available when launched from the widget mode, but not from the application mode (since in the app mode, there is no background reload). In order to install and launch as a widget, just go to the home screen / launcher, long press, then select add widget.

Automatic location finder:

  • With this new version, you can decide to enable the "Automatically select the nearest monitoring station" from the settings menu.
  • This feature will check, each time the AQI is updated (twice an hour), you current location to return the AQI related to the nearest station.
  • This feature is definitely useful for those people who travel a lot, but also, just even when commuting back and forth from home to office.

Forecast:

  • The "forecast tab" will give you the information about the wind and temperature forecast for the coming 3 days.
  • The forecast data is based on the GFS (Global Forecast System) - The wind information contains both wind direction as well as wind speed and wind gust (gust in the peak wind speed). For the temperature, it is based on the 2 meters GFS, and it is currently experimental.
  • Interpreting the wind forecast is very specific to the city you are leaving in. For instance, in Beijing, strong north wind will for sure clean the Air, while winds from the south might bring the pollution from Hebei.

Embedded map:

  • From the "map tab" you will be able to navigate through the world air quality monitoring stations.
  • The best use for the map is in conjunction with the wind forecast: You just need to check the Air Quality in the area where the wind is blowing from to get a good indication on the AQI forecast.
  • Note that the map is using "tile caching" solution, so data does not have to be downloaded each time you check the map, thus reducing data usage.

Sharing:

  • Last, but not the least, you can now share a piclet of the current AQI to your friends in just one click.
  • All you need is to click on the Share icon (), and you will be able to send similar piclets from your phone:

    關於空氣質量與空氣污染指數

    本網站採用的污染指數和顏色與EPA是完全相同的。 EPA的指數可以從 AirNow上查到

    空气质量指数空气质量指数级别(状况)及表示颜色对健康影响情况建议采取的措施
    0 - 50一级(优)空气质量令人满意,基本无空气污染各类人群可正常活动
    51 -100二级(良)空气质量可接受,但某些污染物可能对极少数异常敏感人群健康有较弱影响极少数异常敏感人群应减少户外活动
    101-150三级(轻度污染)易感人群症状有轻度加剧,健康人群出现刺激症状儿童、老年人及心脏病、呼吸系统疾病患者应减少长时间、高强度的户外锻炼
    151-200四级(中度污染)进一步加剧易感人群症状,可能对健康人群心脏、呼吸系统有影响儿童、老年人及心脏病、呼吸系统疾病患者避免长时间、高强度的户外锻炼,一般人群适量减少户外运动
    201-300五级(重度污染)心脏病和肺病患者症状显著加剧,运动耐受力降低,健康人群普遍出现症状儿童、老年人及心脏病、肺病患者应停留在室内,停止户外运动,一般人群减少户外运动
    300+六级(严重污染)健康人群运动耐受力降低,有明显强烈症状,提前出现某些疾病儿童、老年人和病人应停留在室内,避免体力消耗,一般人群避免户外活动
