    • accurate data

      To whom may concern,
      We have been checking the air quality index since last year, however we found the data has such a big difference between your website and another official one which is stated on yours as well. I am wondering which one can provide more accurate data, as it will affect the decision for outdoor or indoor. Please help me with this issue. Thank you!

      • Please fix Wordpress embeds

        The Hong Kong embed, at least, shows Beijing figures.

        • Use US EPA Airnow.gov designations instead of the China's. The China API system is not compatible with PM2.5 AQI

          Use US EPA Airnow.gov designations instead of the China's. The China API system is incompatible with AQI PM 2.5,

          Here is the difference:

          US EPA AirNow China

          0-50 Good Excellent
          51-100 Moderate Good
          101-150 Unhealthy for Sensitive Groups Slightly Polluted
          151 to 200 Unhealthy Lightly Polluted
          201 to 300 Very Unhealthy Moderately Polluted
          301 to 500 Hazardous Severely Polluted

            • Change the color codes to those of EPA

              Hi! You guys really did a great job. One small improvement will make it perfect. The current color codes are not that similar to those of EPA. Especially, the Red seems deeper than Purple, which isn't the case of those of EPA. I think you directly copy the color code from the source of EPA's AQI page.

              Keep on the good job!

              Leon

              • change the Nationwide android app air quality history graph to include 2.5 for the newer cities.

                For example, I live in Dalian, and it displays our 2.5 number, but the history graph in the widget is PM10.

                • add real-time Chongqing PM 2.5 data data

                  that data is already available on other apps as e.g. Air Quality China. This would give us a more clear picture of the Situation. I and many Chongqinger would appreciate.

                  • misspelled city name Chengdu

                    Chengdu, in Chinese 成都, was misspelled to 程度, in Google play store Chengdu air quality page.

                    成都 is the name of the city but 程度 means degree or level, they have the same pronunciation but totally different meaning, please kindly correct this.

                    • Chengdu air quality is not compatible with android 2.3

                      weird, Chengdu air quality's Google play page is telling "This app is incompatible with your device", however all other three cities are supported.

                      I guess there might be something wrong, would you please check why and make correction?

                      • Go back to multiple-city view

                        I really like your web site--thank you. But I preferred the previous home screen which showed AQIs for the other major cities. Perhaps make the long list of all cities on separate page.

                        • Other cities is currently no longer comprehensive

                          I used to be able to see the AQI of all the large cities across China e.g. Qingdao and more and now when I click on other cities there's only a limited few. Can you fix this?
