Korea, Japan, and Sydney Australia: Real-time Air Quality Index

Tamara and I were looking at the Air Quality Index for various places, and just look at the terrible numbers for south-west Sydney because of the fires.

Air Quality Index tab 'hazardous' for south-west Sydney because of the fires.

But also look at the huge difference in air quality between South Korea and Japan. Anything below 50 (green colour tab) is considered good.

I wonder what accounts for the difference in air quality between the two countries?

  1. Manufacturing Cities?

    1. I assumed, perhaps wrongly, that the detection sites would be placed as near to (or in) manufacturing cities in both countries.

      Assuming so, I wonder why Japan seems to have cracked the air pollution problem, while Korea has not?

      Is it because of a different cultural attitude to pollution? Is it because Japan has been a developed economy for longer and has had time to solve the pollution problem? Is it winds and geography? Is it the use of traditional fuels in households in one economy and not in the other? Is it the use of nuclear energy in Japan?

      The questions are only limited by my imagination to think of reasons? 🙂

      I can’t think who to ask who might know the answer.

      1. All very good questions David and very likely a combination of them all…
        I wonder who has the answers?
        As to Australia, I offer this blog post from Ron Miksha’s ‘Bad Beekeeping’: https://badbeekeepingblog.com/2020/01/05/bees-and-the-australian-fires/

    1. Yes, terrible for humans, animals, insects. If it were a one-off then it would be bad. I guess that the underlying fear is that a pattern is set with changing climate.
