- | Usage: | ||
- | bufrdump.pl <bufr file(s)> | ||
- | [--filter <filter file>] | ||
- | [--param < | ||
- | [--lon1 x1] | ||
- | [--lat1 y1] | ||
- | [--lon2 x2] | ||
- | [--lat2 x2] | ||
- | [--tablepath <path to BUFR tables>] | ||
- | [--help] | ||
- | Options: | ||
- | --filter <filter file> | ||
- | Decode observations meeting criteria in <filter file> only | ||
- | --param < | ||
- | Print parameters in < | ||
- | as they occur in < | ||
- | --lon1 x1 | ||
- | --lat1 y1 | ||
- | --lon2 x2 | ||
- | --lat2 y2 | ||
- | x1,y1,x2,y2 should be decimal degrees | ||
- | --tablepath <path to BUFR tables> | ||
- | Set path to BUFR tables (overrides ENV{BUFR_TABLES}) | ||
- | --help | ||
- | |||
- | Options may be abbreviated, | ||
- | |||
- | To avoid having to use the " | ||
- | the invironment variable BUFR_TABLES to the directory where your BUFR | ||
- | tables are located (unless the default path provided by bufrdump.pl | ||
- | works for you). | ||
- | |||
- | The lines in < | ||
- | to be printed. For example, if you want only station identification and | ||
- | temperature to be printed for a BUFR SYNOP file, the < | ||
- | should look like this: | ||
- | |||
- | wmonr | ||
- | DDDD | ||
- | TA | ||
- | |||
- | If you want " | ||
- | in BUFR message, precede the parameter name with an exclamation mark | ||
- | (e.g. ' | ||
- | |||
- | 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 < | ||
- | =, !=, <, <=, > 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. | ||
