Dear all,
While retrieving data from the air quality index I noticed that there is a huge gap in the data for Lisbon in 2020:
[https://db.nomics.world/AQICN/AQI/PT.lisbon.no2.median](https://db.nomics.world/AQICN/AQI/PT.lisbon.no2.median)
The data however appears to exist in the AQICN website:
> **[Air Quality Historical Data Platform](https://aqicn.org/data-platform/register/)**
>
> How polluted is the air today? Check out the real-time air pollution map, for more than 100 countries.
Is there something that I am missing? 🙂
Thanks a lot for any help!
Best,
João

Hi @joaoleal,
Thank you for noticing this problem! Air quality index has released new CSV files for 2020 (“2020Q1.csv”, …, “2020Q4.csv”) instead of just “2020.csv” as before.
I have fixed this problem and you should see it very soon on DBnomics 🙂
Have a great day,
Enzo

Hi @joaoleal,
The issue has been solved in case you did not see 🙂
Have a good day,
Enzo
