MMM image archive This is probably the best "one-stop shop" for looking at archived images. It includes radar composites, satellite images, soundings, surface and upper-air maps, and much more. SPC severe events archive This is another good place to get started with surface and upper air analyses, soundings, etc. It also does have a few archived images for quick looks. MesoWest Outstanding real-time and archived surface observations from both standard sources and the various mesonets around the country.

The map tool uses the Reflectivity Mosaics products and web services provided by the Iowa Environmental Mesonet. Reflectivity is available from to near-real time in five-minute increments. The raw data are not available for download and are only accessible as images on this map or from the Iowa Environmental Mesonet. The typical range of most radar products is km from the radar site. However, mountains can block the lower sweeps of the radar beam. The Interactive Radar Map Tool shows map layers at the maximum distance km , as well as maps derived from geospatial models that provide views of areas blocked by mountains. The analysis conducted by NOAA's Radar Operations Center shows the availability of beam coverage at specified altitudes from the ground.

This data is gathered from over a hundred radar towers located across the US. This is the highest resolution radar data available which enables you to see features such as sea breeze or outflow boundaries that standard resolution radar entirely misses. There is a notable constraint to radar data though. Because the earth is round and the radar beam is flat, the farther away from the radar tower the beam energy travels, the farther removed from the ground becomes. To see this in action, imagine a circle earth with a straight line emanating from some point on the circle if you continue this line out into space, it will gradually get farther and farther from the circle. Because of this phenomenon, the radar beam will only see precipitation falling through the mid levels of the atmosphere. Use radar data with caution especially if your area of interest is far from the nearest radar location! We currently have two types of radar data available with plans to add more soon.

Upper-air Plymouth State Plot your own upper-air maps. Bright reflectivity returns that are stationary and appear during both calm and inclement weather are usually land-based obstructions such as mountains, trees, or especially wind farms nothing gets electromagnetic signals confused like spinning metal blades!

A few tips on reflectivity data:. Because the earth is round and the radar beam is flat, the farther away from the radar tower the beam energy travels, the farther removed from the ground becomes. We currently have two types of radar data available with plans to add more soon. The map tool includes layers at 4, feet best coverage , 6, feet better coverage , and 10, feet fair coverage. No advertising, more exclusive weather content: click here! Reflectivity is available from to near-real time in five-minute increments. If satellite data shows clear skies but you see signatures on radar data, it could be anything from smoke from a fire to a flock of birds taking flight to dust particles collecting along a boundary. Hook echoes- if you see a storm moving towards you that looks like a fish hook, especially a fish hook with a barb on the end, take cover! Because of this phenomenon, the radar beam will only see precipitation falling through the mid levels of the atmosphere. Watch for strong winds along the leading edge of this!
