NEXRAD Intensity<br />
Colors are used to identify the different NEXRAD echo intensities (reflectivity) measured in dBZ<br />
(decibels of Z). “Reflectivity” (designated by the letter Z) is the amount of transmitted power returned to<br />
the radar receiver. The dBZ values increase as returned signal strength increases. Precipitation intensity is<br />
displayed on the <strong>400</strong>/<strong>500</strong> <strong>Series</strong> units using colors represented by the dBz values listed in Table 2-1.<br />
