Index
• Radar base reflectivity is sampled at the minimum antenna elevation angle. An
individual radar site cannot depict high altitude storms at close ranges, and has
no information about storms directly over the site.
• Radar coverage in Canada is only available in the southern 1/4 of the country.
Radar Intensity
Colors are used to identify the different radar echo intensities (reflectivity) measured
in dBZ (decibels of Z). “Reflectivity” (designated by the letter Z) is the amount of
transmitted power returned to the radar receiver. The dBZ values increase as returned
signal strength increases. Precipitation intensity is displayed using colors corresponding
to the dBZ values.

NOTE:
METAR information is only displayed within the installed aviation
database service area.
METAR (METeorological Aerodrome Report) is an international code used for
reporting weather observations. METARs are updated hourly or as needed. METARs
typically contain information about the temperature, dewpoint, wind, precipitation,
cloud cover, cloud heights, visibility, and barometric pressure. They can also contain
information on precipitation amounts, lightning, and other critical data. If METAR data
is available for an airport, a color-coded flag is shown next to the airport.
TAF (Terminal Area Forecast) is the standard format for 24-hour weather forecasts.
TAFs may contain some of the same code as METAR data. It typically forecasts
significant weather changes, temporary changes, probable changes, and expected
changes in weather conditions.
