Dear Uta,



Currently, Fatin and I are exploring the potential of i-Tree software ( https://www.itreetools.org/ ) in assessing the benefit of trees in termterms of economic and ecological aspects in George Town, Penang. In order to run the software with Penangs'Penang's context, we require to submit our application through the i-Tree database.



One type of data needneeded for the application is pollution data per hour for the year 2018 in George Town, Penang. The hourly pollution data can be submitted for particulatethe particular matter is less than 2.5 microns (PM2.5), carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), and sulfur dioxide (SO2).



For your information, currently, we've found a pollution data for the year 2018 from the Ministry of Natural Resources and Environment (KASA) website but the file is only shownshows data on particulatea particulare matter less than 2.5 microns (PM2.5). The file is Pollution Data- Penang 2018 (from Jabatan Alam Sekitar, KASA).xlsx



I wonder if you know any other platform towhere we can find pollution data for the rest of the pollutants such as carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), and sulfur dioxide (SO2) in Penang for 2018.



Thank you.
