If the data has several simultaneous statuses, all these statuses are shown in the status
column.
Table 24 ASCII Log View: Status Codes
Status Code
Data Status at Storage Time
-
(no code)
Normal status. Data comes from a sensor and is valid.
C
(Backup/Copied)
(For optional weather data when LLWAS is integrated with AviMet AWOS) Data
comes from a backup sensor due to a problem with the original sensor.
m
(Manual)
(For optional weather data when LLWAS is integrated with AviMet AWOS) Data is
entered manually by the user due to a problem with the original sensor.
O
(Old)
Data has not been updated for a certain timeout period due to sensor
communication problems, but it is still considered to be valid.
I
(Invalid)
Data is invalid or out of range, and should not be used. Can occur because of a
sensor or data line malfunction.
M
(Missing)
Data is not available due to sensor communication problems. Data has not been
updated and is considered as being missing.
U
(Undefined)
When data has been measured or calculated, but the numerical value cannot be
determined, the status is
Undefined
. For example, cloud layers have been
measured but there are no clouds. Data value may be available, but it should not
be used.
7.2.3 Reports Files
Reports File Parameters
Reports files can include the created weather reports, for example, METAR, as displayed in
the WeatherView application. For LLWAS reports the typical parameters are:
CREATEDATE
The date and time of the measurement. The format is
YYYY-MM-DD hh:mm:ss
.
CENTERFIELD
Centerfield wind direction, wind speed, and measurement time. For example,
CF 000
00 12:30:30
PROCESS_ST
Processing status of the LLWAS algorithm. For example,
DEGRADED
. For details, see
below.
Runway name
The LLWAS data for the specified runway as displayed in the WeatherView
application. For example,
02RA WSA RWY 30K+ 030 15
RWY02RA_%
The percentage indicates how close to the windshear or microburst alert limit the
situation on the specified runway is. A figure over
100
indicates a windshear or
microburst alert.
