Im reaching out to request the raw PM2.5 data over 11 years period (2010-2021) for South Korea. We are conducting the research which need to look at the spatial and temporal trend of PM2.5. What I found is South Korea has more than 100 censors and the number of sensors varied across time period. I tried out several way to access data.
Request data from Sensor data download tool which we can download multiple data from multiple desired sensors. I tried this way, but it takes time to download even several sensors a time. And this has a limitation that data will be loaded in separated file corresponding to each sensor without location detail information (longitude & latitude).
Request data using API key, I’m contacting them for the key, and it seems the API key will be provided within 24 hours. By this way, there are limit on API to download multiple censor data within a wide range of time. But still, we need the key to try.
I also contact Purpleair via email however I have not received the response.
As we need the data urgent, I would like to leave a request via the browser.
I hope to receive your response soon.
The data I want are as the structure below:
