ZDR LIMITATIONS - Susceptible to the same data quality limitations as traditional reflectivity • Attenuation and degraded signal through heavy precipitation areas • Same VCP’s are used and data still susceptible to range folding
CORRELATION COEFFICIENT(CC) -A measure of the correlation of the horizontal and vertical back scattered power within a radar sample volume. VALUE 0.96 to 1 Small diversity in hydrometeors within the sample volume 0.85 to 0.95 Large diversity in hydrometeors Less than 0.85 Non-hydrometeorological targets
