ADDITIONAL FEATURES

NEXRAD Intensity

Colors are used to identify the different NEXRAD echo intensities (reflectivity) measured in dBZ (decibels of Z). Reflectivity (designated by the letter Z) is the amount of transmitted power returned to the radar receiver. The dBZ values increase as returned signal strength increases. Precipitation intensity is displayed on the GNS 530 units using colors represented by the dBZ values listed in Table 14-3.
