The short answer is that the National Weather Service replaced the N?Q family of products (Digital Base Reflectivity) with "super-resolution" counterparts that have the identifier N?B, where ? Doppler radars detect atmospheric precipitation and winds, which allow scientists to track and anticipate weather events, such as rain, ice pellets, snow, hail, and tornadoes, as well as some non-weather objects like birds and insects. The address to this website was the same hostname as the main IEM website. Nexrad radar sites provide data in two formats: Level 2 and Level 3. The radar scan times 4.5, 5, 6 or 10 minutes depending on the selected VCP. Super resolution makes a compromise of slightly decreased noise reduction for a large gain in resolution. What are Level II data? This redirect creates needless load on the servers and is not efficient. Are you sure you want to create this branch? The IEM receives a feed of NEXRAD Level III products from the Unidata Internet Data Distribution.

General products for Level 3 include the base and composite reflectivity, storm relative velocity, vertical integrated liquid, echo tops and VAD wind profile. #1 I know that Iowa State has a Level II data feed for free, but which is susceptible to overloading on significant days, and Allisonhouse has the more robust feed for a monthly fee. Data coverage varies by station and ranges from May 1992 to 1 day from present. In production NSS data that is truncated has been found. Users assume responsibility to determine the usability of these data. With the advent of dual polarization beginning in 2011, additional base products of differential reflectivity, correlation coefficient and differential phase are available.
