RADAR + Satellite Data
The IEM generates composites of NWS NEXRAD data. These composites are used to generate various products on the IEM website.
- MidWest Composite w/ warnings
- US Composite w/ warnings
- Convective Watches Overview
- Yesterday (GMT) CONUS Max dBZ Composite
- Yesterday (GMT) Iowa Max dBZ Composite
Raw Level II Data:
The NWS operated WSR-88D RADARs produce data and products in different formats. Once of these formats is called "Level II" and is high resolution information without much of the processing "Level III" products have.
GIS Web-Mapping Apps:
These applications utilize the NEXRAD composites generated by the IEM.
