• Radar base reflectivity does not provide sufficient information to determine cloud
layers or precipitation characteristics (wet hail vs. rain). For example, it is not
possible to distinguish between wet snow, wet hail, and rain.
• Radar base reflectivity is sampled at the minimum antenna elevation angle. An
individual radar site cannot depict high altitude storms at close ranges. It has
no information about storms directly over the site.
• When zoomed in to a range of 30 nm, each square block on the display represents
an area of four square kilometers.
The following may cause abnormalities in displayed radar images:
• Ground clutter
• Strobes and spurious radar data
• Sun strobes (when the radar antenna points directly at the sun)
• Interference from buildings or mountains, which may cause shadows
• Metallic dust from military aircraft, which can cause alterations in radar scans
