This notebook picks up from our introductory notebook, [OpenAQ Direct File Access from Open Data on AWS](https://observablehq.com/@openaq/openaq-open-data-on-aws), which provides an overview of how files are organized in the Open Data on AWS bucket. If you have not read that notebook we recommend reading through that first to gain a general understand of the bucket.
