      • Global Pollution Comparison

        A good idea might be to show a comparison of Hong Kong air quality compared to other global cities. As they do with world clocks.

          • adding PM 2.5 measurement

            Could you also introduce measurements of the PM 2.5 particles? They are considered more health risky than the larger PM 10 particles that are measured regularly. This information may prove important and helpful.
            Thank you.

            • your numbers are higher

              you numbers are higher than other websites, including the original pm2.5 readings.
              I and maybe many one wants to know why.

              • history data

                Good WEBSITE!
                It would better if you can provide a way to access history data including wind and PM2.5 data so that guys interest in them can analyse the correlation between them.

                • How can PM2,5 exceed PM10?

                  Hi, I wondered how it’s possible that on your site, given a certain location, PM2,5 is usually a lot more than PM10. This surprises me, since PM2,5 is particles with a diameter smaller than 2,5 micron, and PM10 is particles smaller than 10 micron. Everything that’s smaller than 2,5 micron is also smaller than 10 micron, so one would think that the value for PM2,5 can never exceed the value for PM10. Can anyone explain this to me?

                  • Yearly statistics

                    It would be great to have statistics for the last 12 months, with one chart for each month that would show average for a individual hour like in existing charts.

                    It's very useful when you are thinking to move somewhere on a longer period.

                    Thanks for doing great job!

                    • Add outdoor exercise advice to the AQI table

                      On your http://aqicn.org/mask/ page, you have advice about safety of outdoor activity at certain levels. However that advice is located in the PM2.5 vs Visability graphic, and visibility distance isn't practical or accurate for many people to measure. Since you already have a AQI table describing each AQI range, please add actionable advice there, like "Reduce outdoor activities", etc.

                        • Offer a Map

                          I am interested in teaching English in China. I wanted to know whether some regions have better air quality than others. It would be helpful to see a map showing the colored boxes (e.g., yellow = moderate) for different regions.

                            • would like to check one data

                              Hi I love your website and am a frequent daily user.

                              Just want to highlight that the index for Mongkok in HK is consistently lower than that of other areas in HK. Mongkok is highly polluted area so I thought it might be worth checking!!!

                              Thanks and have a good day.

                                  Please consider including an e-mail alert service. This would allow users to specify a city and pollution level that they would like to receive alerts for. That way, users get notified when the pollution levels reach the levels they have pre-defined.This information can be used to know when to wear a face mask or when to turn on indoor air purifiers.
