Supplemental Weekly Precipitation Data in Iowa
These supplemental rain gage data in Iowa are observations received at the National Weather Service River Forecast System, and are supplied by the Iowa State Climatologist within the Iowa Department of Agriculture.

The data are mostly unofficial and frequently non-continuous. Many sites take observations only on days with measureable precipitation. The data format approximates TD-3200, a format used by the National Climatic Data Center. A listing of sites included and an example of the decoding appears below. Some sites have official, 6-digit Cooperative Observer identification numbers; others are numbered sequentially. Data are arranged in weekly reports by station number, and are available from 3/1/93 to 4/18/93 and 5/31/93 to 10/3/93.
