Usage:
bufrread.pl <bufr file(s)>
[--codetables]
[--data_only]
[--param <descriptor file>]
[--filter <filter file>]
[--bitmap]
[--noqc]
[--outfile <filename>]
[--optional_section]
[--width n]
[--strict_checking n]
[--on_error_stop]
[--all_operators]
[--tablepath <path to BUFR tables>]
[--verbose n]
[--help]
Options:
--codetables Use code and flag tables to resolve values when unit
is [CODE TABLE] or [FLAG TABLE]
--data_only Print section 4 (data section) only
--param <descriptor file>
Display parameters with descriptors in <descriptor file> only
--filter <filter file>
Decode observations meeting criteria in <filter file> only
--bitmap Display bit-mapped values on same line
--noqc Do not decode quality control
(or any descriptors following 222000)
--outfile <filename>
Will print to <filename> instead of STDOUT
--optional_section
Display a hex dump of optional section if present
--width n Set width of field used for data values to n characters
(default is 15)
--strict_checking n n=0 (default) Disable strict checking of BUFR format
n=1 Issue warning if (recoverable) error in
BUFR format
n=2 Croak if (recoverable) error in BUFR format.
Nothing more in this message/subset will be decoded.
--on_error_stop Stop processing as soon as an error occurs during decoding
--all_operators Show all operator descriptors when printing section 4
--tablepath <path to BUFR tables>
Set path to BUFR tables (overrides ENV{BUFR_TABLES})
--verbose n Set verbose level to n, 0<=n<=6 (default 0). n=1 will
show the tables loaded.
--help Display Usage and explain the options used. For even
more info you might prefer to consult perldoc bufrread.pl
Options may be abbreviated, e.g. "--h" or "-h" for "--help".
To avoid having to use the "--tablepath" option, you are adviced to set
the invironment variable BUFR_TABLES to the directory where your BUFR
tables are located (unless the default path provided by bufrread.pl
works for you).
Each line in <descriptor file> should start with a BUFR descriptor (6
digits). Rest of line will be ignored. bufrread.pl will display values
for these descriptors only.
Using "--filter" will decode only those observations that meet one of
the criteria in <filter file> (and all of those criteria marked D!).
Comments (starting with #) are ignored. An example of a filter file is
D: 001001
1
D: 001001 001002
3 895
6 252
D: 001011
LF5U # Ekofisk
D!: 004004
6
7
which decodes all observations with block number 01, two other specific
WMO stations and one specific ship, all of which having hour (004004)
equal to 6 or 7. If there is no value line after a descriptor line, it
is enough that the observation contains the descriptor(s), whatever the
values are. So to extract all ship messages from a BUFR SYNOP file, the
filter file should contain this single line only:
D: 001011
If an error occurs during decoding (typically because the required BUFR
table is missing or message is corrupt) the message is skipped, and the
number of errors is reported at end of output. You can change this
default behaviour, however, by setting "--on_error_stop".
