Base Reflectivity displays the 150-mile reflectivity sweep of the site. This product is
available only for the first four scans of the volume.
Composite Reflectivity shows the greatest reflectivity at a location, regardless of height.
Base Velocity displays wind speed and direction in reference to the radar beam. It is
available only for the first four scans of the volume.
Storm Relative Velocity displays Storm Relative Velocity (SRV), which indicates wind
speed and direction relative to storm movement. SRV is available only for the first two
scans of the volume.
Shear products, such as SRV Shear (Storm Relative Velocity Shear) and BV Shear (Base
Velocity) are the respective velocity products, showing the amount of gate-to-gate shear on
adjacent radials. SRV Shear is available for the first two scans of the volume. RV Shear is
available for the first four scans of the volume.
Composite Shear is derived from both Storm Relative and Radial shears, showing the
greatest shear, regardless of the storm’s velocity or height.
Baron Button enables the system to display a special product designed to provide an
overall assessment of a storm in one display. It incorporates Rain Rate, VIL Density, and
Composite Shear parameters into one product.
Vertically Integrated Liquid (VIL) uses the water content feature to estimate the
amount of water in kilograms per meter squared (kg/m
2
). Its primary use is for hail
detection.
VIL Density uses the NEXRAD VIL and Echo Tops products to determine the amount
of water in kilograms per meter cubed (kg/m
3
). This gives a more accurate reflectivity
reading of surface hail that meets or exceeds 18.5 dBZ.
Echo Tops indicates the highest altitude that the radar senses.
Storm Total graphically represents the total rain in an area after the radar mode changes
from Clear Air Mode to Precipitation Mode.
Rate shows the amount of rainfall, in inches per hour, for a given time period.
C01 indicates that no recent data has been received from the site.
C02 indicates that the radar is in Clear Air Mode.
R01 displays the precipitation type forecast grid for the eastern U.S.
The 1 hr and 3 hr buttons show the estimated rain accumulations over one-hour and
three-hour periods.
