Figure 13 depicts the process used by the RPG to build the Base Reflectivity products. The average returned power from 4 consecutive range bins (0.13 nm resolution) is assigned to each 0.54 nm resolution range gate, then converted to dBZ. To format Base Reflectivity data into 1.1 nm and 2.2 nm displayable resolutions, the highest 0.54 nm range gate value included within the bounds of the coarser (1.1 or 2.2 nm) resolution is assigned to the coarser resolution range gate. Retaining the highest reflectivity value for display in the coarser resolutions preserves important features such as maximum reflectivity values in the cores of strong thunderstorms.

Reflectivity values are listed as well as color coded. 13. WSR-88D technique for displaying Base Reflectivity for Super-Resolution (0.5 deg azimuthal, 0.25 km

Figure 14 depicts the process used at the RPG to build the Base Velocity and Spectrum Width products. These resolutions display data from every, every other, or every fourth range bin, respectively, as the value for each lower resolution range gate. This may result in peak velocity or spectrum width values not being displayed at lower resolutions. The maximum displayable ranges for the resolution levels listed above are 32, 62, and 124 nm, respectively.
