For data science and research, you can download historical weather for many locations and dates as one file instead of calling
history.json for each: up to 500 locations per export, from 1 January 2010 to yesterday, daily or hourly,
as gzipped CSV (one row per day or hour, with nested fields as columns such as condition_text and aq_pm2_5) or
JSON Lines. Air quality can be included from March 2021.
Request an export from Bulk history export in your dashboard. We email you when it's ready, usually within an
hour, and you download it for 7 days. Or have it delivered straight to your own Amazon S3 (or S3-compatible) bucket: paste a pre-signed upload
(PUT) URL, created with aws s3 presign or your SDK; we never ask for your keys.
Available on Enterprise plans; contact us to add it. Each account can export up to 2,000,000 location-days a month (a location-day is one location for one day).
