I need real-time PM 2.5 historical data of sensors in eastern North Carolina for my MS thesis. The real-time PM 2.5 historical data I need is between September 25, 2021, to April 10, 2022, from all the sensors in eastern North Carolina, US, at Eastern Time (not UTC).
Having spent time reading through the Purpleair website and documentation, I realized that there are two methods of downloading sensor data from the Purpleair website, i.e., through the purple air API calls or the Data download tool. I have watched the tutorial video on how to download data using the data download tools, and it is quite interesting. I found the process more efficient as it does not require programming.
I have used the Purpleair develop tool to create API keys which is one of the requirements to download the data. Using the data download tool, the request information and sensor information sections were properly filled, but when I clicked on the “Get data” button, the progress threw an error “Payment is required to make this api call.”
I need assistance on how to download the data with all the requirements. I appreciate your help. Thank you.
