Open data

The Generalitat de Catalunya publishes what its measuring networks record, and most of it is only ever looked at a day at a time. These pages add it up another way and keep the picture that came out.

The sums are kept in this site's repository, a finished year at a time, and the portal is asked again only when a year has ended. While you read, nothing is fetched from anyone but this site.
