(4) Vertical Visibility (VV) -- may be listed here
for indefinite ceiling such as "VV004" for
Vertical Visibility 400 ft
(5) Temperature/Dew Point -- listed in degrees
Celsius
NOTE: When temperatures are below
0 degrees C, they are preceded by "M" for
minus (e.g., 10/M06 for temperature 10
degrees C, dew point -6 degrees C).
(6) Altimeter Setting -- (ex. A2992) "A"
indicates setting in inches of mercury for
United States. Consists of 4 digits: inches
and hundredths
(7) Remarks (RMK) come last
(a) RMK SLP013 T01760158 -- Selected
stations will contain SLP for sea level
pressure reported as the last 3 digits in
hectoPascals (millibars) to the nearest
tenth (e.g., 1001.3 is reported as
SLP013)
(b) RMK SLP013 T01760158 --
9-character code breaks down the
temperature and dew point to the
nearest 1/10th of a degree Celsius
(selected stations)
(i)
The "T" stands for temperature
(ii) The "0" means positive
temperature
(iii) A "1" in place of the "0" stands for
negative temperature
(iv) Other temperature codes, such as
10142, 20012, or 401120084,
may appear to document
temperatures not related to
aviation (selected stations)
