Produced by the Oklahoma Climatological Survey, the Oklahoma Climate Data Web site offers information on various weather topics for the state that include normals and extremes, a rainfall update, monthly summaries, climate event summaries, and a weather timeline. The data is presented in tables, charts, illustrations, or Adobe Acrobat (.pdf) files (e.g., the timeline that goes back to 1900). A very interesting collection of facts, this site is a great example of a public agency offering quality information of their work to the public.
