Usage: /metno/local/bin/bufrdump.pl <bufr file(s)> [options]
Will print section 4 in BUFR messages in <bufr file(s)> as "parameter=value" lines.
Options (may be abbreviated, e.g. --h for --help) are:
--filter <filter file>
Decode observations meeting criteria in <filter file> only
--param <parameter file>
Print parameters in <parameter file> only, in same order
as they occur in <parameter file>
--lon1 x1 Decode observations with longitude >= x1 only
--lat1 y1 Decode observations with latitude >= y1 only
--lon2 x2 Decode observations with longitude <= x2 only
--lat2 y2 Decode observations with latitude <= y2 only
x1,y1,x2,y2 should be decimal degrees
--tablepath <path to BUFR tables>
Set path to BUFR tables (overrides ENV{BUFR_TABLES})
--help Print this Usage
You should probably set
export BUFR_TABLES=/usr/local/lib/bufrtables
or use the --tablepath option.
The lines in <parameter file> should be name of the parameters you
want to be printed. For example, if you want only station
identification and temperature to be printed for a BUFR SYNOP file,
the <parameter file> should look like this:
wmonr
DDDD
TA
If you want "parameter=value" to be printed also when value is missing
in BUFR message, precede the parameter name with an exclamation mark
(e.g. '!TA'). Missing values will then be displayed as -32767.
Using --filter will decode only those observations that meet at least
one of the BUFR descriptor criteria and all of the parameter criteria
in <filter file>, where the BUFR descriptor criteria should come first
in filter file followed by a blank line, then comes the parameter
criteria which should match <param> <operator> <value> where operator
is one of =, !=, <, <=, > and >=. An example filter file is
D: 001001 I2.2
01
D: 001001 I2.2 001002 I3.3
03 895
06 252
D: 001011 A9
LDWR
NN != 0
TA >= 5
TA < 9.5
which decodes all observations with block number 01, two other
specific wmo stations and one specific ship, having cloud cover
different from 0 (but NN must be part of the message) and temperature
between 5 and 9.5 degrees Celsius. Comment lines starting with #
will be ignored.
