# Rain Historic precipitation data is available through the Met Office Hadley Centre observations datasets: HadUKP. HadUKP is a dataset series of UK regional precipitation, which incorporates the long-running England & Wales Precipitation (EWP) series beginning in 1766, the longest instrumental series of this kind in the world. The data is available on a regional basis, so we have taken a copy of the South West daily totals data. These provide a daily precipitation value since 1931. This data is provided as a text file with a row for each month, values separated by spaces. A python script in this repository converts the data into a friendlier CSV file. * [Download HadSWEP CSV](https://github.com/LibrariesWest/opendata/tree/4b45515af84fd24c38d0a877b9b550f2493c6cd8/weather/HadSWEP.csv) | Field | Description | Example | | ------------- | -------------------------------------------------- | ---------- | | Date | The date measured | 2016-06-19 | | Precipitation | Daily Southwest England & Wales precipitation (mm) | 21.50 | ## Licence Data is made available under the Open Government Licence, with a requirement to attribute the original source, which is the [Met Office Hadley Centre](https://www.metoffice.gov.uk/hadobs/hadukp/). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
