Dataset: lod-katrina (development version)

The Katrina dataset from the Linked Observation Data collection by the Kno.e.sis Center describes weather measurements from many weather stations across the US during the Katrina hurricane. See more details on LOD Cloud and the original website (Internet Archive). See also the paper.

This README is a snapshot of documentation for the latest development version of the dataset. Full documentation for all versions can be found on the website.
