Context
The idea is to have a very simple time series dataset to be used for experiments with easy but effective visualizations on actual data.
It is amazing how much a single graph can comunicate syntehetically a lot of information.
Content
The dataset was downloaded from the National Centers for Environmental Information (NCEI), the data is in the public domain and can be used freely.
If interested in generating a similar dataset from another station you can start from the Search Tool select Daily Summaries, the time range of interest, search for Cities and in the Search Term put the city you're looking for.
When selected you need to add to Cart like an order but there is no charge for ordering data from Climate Data Online as explained in their FAQs.
Acknowledgements
Thanks to National Centers for Environmental Information for collecting and making available for free meteorological data from many stations all over the world.
In case using the same dataset or generating a new one from NCEI you need to cite the origin.
Inspiration
Mostly to see how many different effective visualizations can be generated from a very simple dataset.
