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 ? Does anyone know why and if there is a different Folks using the redirect think the actual level II website is down or very slow, when it is actually fine. The upgraded Super Resolution data provides radar reflectivity at 0.5 degree azimuthal by 250 m range gate resolution to a range of 460 km, and Doppler velocity and spectrum width at 0.5 degree azimuthal by 250 m range gate resolution to a range of 300 km. Such surfaces are useful in distributed hydrologic modelling and early warning systems in flood management. Special Marine Warning.
