NEXRAD is a network of 160 high-resolution Doppler weather radars operated by the NOAA National Weather Service (NWS), the Federal Aviation Administration (FAA), and the U.S. Air Force (USAF). In-flight icing and hail detection algorithms have enhanced overall data quality in present-day NEXRAD. The DVL version of the product provides a higher spatial resolution and enhanced processing. The address to this website was the same hostname as the main IEM website. These checks include: The parser will also return rich error where possible indicating that a specific product or packet type is not supported. During 2008, the WSR-88D radars were upgraded to produce increased spatial resolution data, called Super Resolution. From these Level 2 data, computer processors generate numerous meteorological analysis Level 3 products based on the Level 3 product algorithms. Level II data are the digital radial base data (Reflectivity, Mean Radial Velocity, and Spectrum Width) and Dual Polarization variables (Differential Reflectivity, Correlation Coefficient, and Differential Phase) output from the signal processor in the Radar Data Acquisition unit.

With the advent of dual polarization beginning in 2011, additional base products of differential reflectivity, correlation coefficient and differential phase are available. In production NSS data that is truncated has been found. The recommended practice is to test that your desired data structure exists in the returned object before doing any further processing with it. 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 ?
