AQS hourly data for July 2023

Hello,

I am writing to inquire about the expected availability of pre-generated hourly AQS data for July 2023. From the EPA’s website (https://aqs.epa.gov/aqsweb/airdata/download_files.html#Raw), I have noticed that hourly observational data is available up to June 2023. We are working on a project for July 2023 and we wish to use this data for evaluation at the earliest opportunity. June this year might be too late for our project. Could you please let me know when the pre-generated AQS data for July 2023 can become available? We are interested in O3, PM2.5, PM2.5 species, and NOx.

Best,
Ying
