The maximum range of the base reflectivity product is 143 miles (230 km) from the radar location. Base reflectivity images are available at several different elevation angles (tilts) of the antenna the base reflectivity image currently available on this website is from the lowest "tilt" angle (0.5°). "Reflectivity" is the amount of transmitted power returned to the radar receiver after hitting precipitation, compared to a reference power density at a distance of 1 meter from the radar antenna. The Local Radar base reflectivity product is a display of echo intensity (reflectivity) measured in dBZ (decibels).
Precipitation intensity is measured by a ground-based radar that bounces radar waves off of precipitation.
