When I look at the fine dust level, I usually see it on aqicn.org, and it says it's very high here, but Naver is much lower than this. Today, aqicn.org is around 200, and Naver is only around 100. I know that Naver and Naver show the environmental level

Even with the same data, there is a difference in the way the index is calculated. Air Korea including Naver is based on CAI. This is also by WHO standards.
In the case of aqicn.org, we use the AQI method. It is because it is based on AQI in China.
It is better to understand that the method of calculating the index is different than what is right or wrong, so it is meaningless to compare the two values that come out.
Oh... Thank you for the detailed explanation. That's why. It was very helpful.
For your information, the data displayed on tenki.jp in Japan does not show pm10, but only pm2.5 is displayed.
