Precipitation Limitations
Radar images may have certain limitations:
• 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
Infrared Satellite
Infrared Satellite (IR SAT) data depicts cloud top temperatures from satellite imagery.
Brighter cloud top colors indicate cooler temperatures occurring at higher altitudes.
Displaying Cloud Tops information
1) Select the Weather Data Link (CNXT) Page.
2) Select the IR SAT Softkey.
To display the Infrared Satellite legend, select the LEGEND Softkey when Infrared
Satellite data is selected for display.
Data Link Lightning
Lightning data shows the approximate location of cloud-to-ground lightning strikes.
A strike icon represents a strike that has occurred within a two-kilometer region. Neither
cloud-to-cloud nor the exact location of the lightning strike is displayed.
If the aircraft is also equipped with an on-board lightning detection system (e.g., L-3
WX-500 Stormscope
®
), only one lightning product may be enabled for display at a time.
