explanations and examples of the exceptions.
8.3.1 Location and Time. The location/name and
the phrase “AUTOMATED WEATHER OBSERVATION”
followed by the time are announced.
8.3.1.1 If the airport's specific location is included in
the airport's name, the airport's name is announced.
EXAMPLE-
“Bremerton National Airport automated weather
observation one four five six zulu.”
“Ravenswood Jackson County Airport automated weather
observation one four five six zulu.”
8.3.1.2 If the airport's specific location is not
included in the airport's name, the location is
announced followed by the airport's name.
EXAMPLE-
“Sault Ste. Marie, Chippewa County International Airport
automated weather observation.”
“Sandusky, Cowley Field automated weather
observation.”
8.3.1.3 The word “TEST” is added following
“OBSERVATION” when the system is not in
commissioned status.

Federal Aviation Administration Nineteenth Edition
EXAMPLE-
“Bremerton National Airport automated weather
observation test one four five six zulu.”
8.3.1.4 The phrase “TEMPORARILY INOPERATIVE”
is added when the system is inoperative.
EXAMPLE-
“Bremerton National Airport automated weather
observing system temporarily inoperative.”
8.3.2 Ceiling and Sky Cover
8.3.2.1 Ceiling is announced as either “CEILING”
or “INDEFINITE CEILING.” The phrases “MEASURED
CEILING” and “ESTIMATED CEILING”
are not used. With the exception of indefinite ceilings,
all automated ceiling heights are measured.
EXAMPLE-
“Bremerton National Airport automated weather
observation one four five six zulu, ceiling two thousand
overcast.”
“Bremerton National Airport automated weather
observation one four five six zulu, indefinite ceiling two
hundred.”
8.3.2.2 The word “CLEAR” is not used in AWOS
due to limitations in the height ranges of the sensors.
No clouds detected is announced as, “No clouds
below XXX” or, in newer systems as, “Clear below
XXX” (where XXX is the range limit of the sensor).
EXAMPLE-
“No clouds below one two thousand.”
“Clear below one two thousand.”
8.3.2.3 A sensor for determining ceiling and sky
cover is not included in some AWOS. In these
systems, ceiling and sky cover are not announced.
“SKY CONDITION MISSING” is announced only if
the system is configured with a ceilometer, and the
ceiling and sky cover information is not available.
8.3.3 Visibility
8.3.3.1 The lowest reportable visibility value in
AWOS is “less than 1/4.” It is announced as
“VISIBILITY LESS THAN ONE QUARTER.”
8.3.3.2 A sensor for determining visibility is not
included in some AWOSs. In these systems, visibility
is not announced. “VISIBILITY MISSING” is
announced only if the system is configured with a
visibility sensor and visibility information is not
available.
8.3.4 Weather. In the future, some AWOSs are to
be configured to determine the occurrence of
precipitation. However, the type and intensity may
not always be determined. In these systems, the word
“PRECIPITATION” will be announced if precipitation
is occurring, but the type and intensity are not
determined.
8.3.5 Remarks. If remarks are included in the
observation, the word “REMARKS” is announced
following the altimeter setting. Remarks are
announced in the following order of priority:
8.3.5.1 Automated “remarks.”
a) Variable visibility.
b) Density altitude.
8.3.5.2 Manual input remarks. Manual input
remarks are prefaced with the phrase “OBSERVER
WEATHER.” As a general rule the manual remarks
are limited to:
a) Type and intensity of precipitation.
b) Thunderstorms, intensity (if applicable), and
direction.
c) Obstructions to vision when the visibility is less
than 7 miles.
EXAMPLE-
“Remarks...density altitude, two thousand five
hundred...visibility variable between one and two...wind
direction variable between two four zero and three one
zero...observed weather...thunderstorm moderate rain
showers and mist...thunderstorm overhead.”
8.3.5.3 If an automated parameter is “missing” and
no manual input for that parameter is available, the
