WebReflectivity is expressed on a logarithmic scale in units called dBZ. The "dB" in the dBz scale is logarithmic and is unit less, but is used only to express a ratio. The "z" is the ratio of the density of water drops (measured in millimeters, raised to the 6th power) in each cubic meter (mm^6/m^3).

Web1. feb 2024 · Gloss and sheen reflectance are measured on a scale of 0 (no gloss) to 100 (mirror-like). Reflectance is typically measured by deflecting a single beam of light at a specific angle off a surface. The light is deflected into a receptor, which measures the intensity in units. The higher the number of units, the shinier the surface. Webreflectivity from the WSR-57’s or WSR74’s was plotted as 6 levels of reflectivity called VIP (Video Integrator Processor) levels. NEXRAD data plotted as VIP levels can be found on an Aviation Digital Data Service radar page showing radar coded messages .
