Archived Data Schema

The IEM maintains two directly web-accessible trees of archived weather products. This page provides a crude schema of what products are archived and where within the directory tree you can find them. The reason there are two archives is that the products have different funding / support resources and legacy.

The products are generally organized by UTC date, but some of the products found are for the local/Iowa calendar date.
