Composite reflectivity
Composite reflectivity bụ ihe mgbagwoju ike dBZ kachasị site na akụkụ ọ bụla nke radar ihu igwe NEXRAD.[1][2] Ntụgharị na akụkụ PPI ọ bụla na-egosi ike mmiri ozuzo na akụkụ ahụ kpọmkwem n'elu horizon. Ụfọdụ n'ime akụkụ ndị a bụ .5, 1.45, 2.4, na 3.35 degrees na Doppler radar nwere ihe rúrú akụkụ iri na anọ mgbè ọ nọ na Severe Mode. Na Composite, a ga-egosipụta ike kachasị elu n'etiti ndị dị na akụkụ dị íchè íchè n'elu ébé ọ bụla nke onyinyo ahụ. Na netwọk radar ihu igwe nke Canada, a na-akpọ nke a MAXR, màkà Maximum reflectivity na kọlụm ahụ.
Màkà radar WSR-88D, nkè National Weather Service na-eji, ngwaahịa radar nke na-egosipụta ihe na-egbuke egbuke na-achịkọta data site na akụkụ niile dị elu nke ihe a nyèrè iji gosipụta nkezi nke ihe ahụ.[3] Ngwongwo radar kacha elu na-egosipụta ihe na-ejikọta data site na akụkụ niile dị elu nke ihe a nyèrè iji gosipụta ihe kacha elu nke ihe ahụ.[4]
