Products Guide
Legacy Composite Reflectivity - UnQCed
Short Description
The maximum reflectivity in a vertical column using all available WSR-88D radars at a horizontal grid point.
Subproducts
None
Primary Users
NWS: WFO, CWSU, AWC, SPC
Input Sources
Single-site WSR-88D radars
Resolution
Spatial Resolution: 0.01o Latitude (~1.11 km) x 0.01o Longitude (~1.01 km at 25oN and 0.73 km at 49oN)
Temporal Resolution: 2 minutes
Product Creation
At each horizontal 2D grid point, the maximum reflectivity value from all available radars at that grid point is retained.

References
None
Strengths
None yet identified
Limitations
The height of the maximum reflectivity is not identified
Quality Control
None
Applications
As with single-radar composite reflectivity, this product is a good situational awareness tool to determine first convective echo, as well as the overall extent of mature thunderstorm echoes (especially in the echo overhang region). To see a quality controlled version using the 3D Reflectivity Cube, refer to “Composite Reflectivity.”
Helps identify non-meteorological echoes (i.e., fine lines; Fig. 1) that might be associated with fronts, boundaries, etc.
