If you select 'National radar', you also have various products to choose from. A legend appear across the bottom of the map for each product, such as the amount of precipitation, in inches, if viewing a precipitation product. You can see various products, including 'Super Resolution Base Velocity', 'One Hour Precipitation Accumulation' and 'Storm Total Precipitation', among others. Click that to view a list of available products. By default, it is 'BREF.RAW', which is 'Super Resolution Base Reflectivity'. Next to the four character identifier for that radar site will be the product that is currently selected. You can then access products specific to that radar site. A circle represents a NEXRAD radar site and a square rotated 45° is a TDWR radar site. If you select 'Local radar', you can then choose what local radar you want to view data from by clicking a dot on the map. That option is available by clicking the square icon, which has two squares in it, which is to the left of the magnifying glass icon. In the enhanced display, you can choose between 'Local radar' and 'National radar'. It also shows you how you can download a KML file of radar imagery for a particular radar site that can be opened in a program like Google Earth. Their radar FAQ page also has information about where to find WMS layers that you can use to add the radar imagery to your own site or application. Additionally, a NWS Webinar on the new display can be found in the YouTube video here.

To use the enhanced display, you may find the videos on their FAQ page here to be helpful, especially the 'Full tour' here. The display can be a bit confusing to use. In addition to Next Generation Weather Radar (NEXRAD Wikipedia article) data, you can also view imagery from Terminal Doppler Weather Radar (TDWR Wikipedia article) sites.

This new display is much more complex to use than their previous display, though it does contain a significant amount of additional products, including more imagery types. In December 2020, they updated their radar display to version 2, which was designed to be mobile friendly. RIDGE stands for 'Radar Integrated Display with Geospatial Elements'. Example of NOAA's enhanced RIDGE II display.
