Function/Subroutine Documentation

istdesc()

integer function istdesc

(

integer, intent(in)

idn

)

Given the WMO bit-wise representation of an FXY value for a descriptor, check whether the descriptor is WMO-standard.

If a descriptor is not WMO-standard, then by definition it is a local descriptor.

Parameters

idn	- WMO bit-wise representation of FXY value for descriptor

Returns

istdesc - Flag indicating whether idn is a WMO-standard descriptor:

• 0 = No
• 1 = Yes

stdmsg()

subroutine stdmsg

(

character*1, intent(in)

cf

)

Specify whether BUFR messages output by future calls to message-writing subroutines and subset-writing subroutines should be internally reformatted to remove all NCEPLIBS-bufr software extensions to the WMO standard, prior to actually writing each message.

It is strongly recommended to use this subroutine (or, alternatively, subroutine stndrd() for messages which already exist in memory arrays) whenever BUFR messages are being written that will potentially be read using software other than the NCEPLIBS-bufr software. Otherwise, by default the output messages will contain a number of extensions to allow for faster reading and more efficient storage, but which will be encoded using non-standard descriptors in Section 3, and therefore likely be unrecognizable to other software packages.

The specified value for cf will remain in effect for all future calls to message-writing subroutines and subset-writing subroutines for all Fortran logical units that are open for output within the application program, unless a subsequent call is made to this subroutine to reset the value of cf again. If this subroutine is never called, a default value of 'N' is used for cf.

Parameters

cf	- Flag indicating whether future BUFR output messages are to be standardized: 'N' = No (the default) 'Y' = Yes

stndrd()

recursive subroutine stndrd	(	integer, intent(in)	lunit,
		integer, dimension(*), intent(in)	msgin,
		integer, intent(in)	lmsgot,
		integer, dimension(*), intent(out)	msgot
	)

Standardize a BUFR message.

This subroutine performs the same function as subroutine stdmsg(), except that it operates on a BUFR message passed in via a memory array and returns its output via a separate memory array, whereas stdmsg() operates on BUFR messages stored internally within the software.

Remarks

• msgin and msgot must be separate arrays
• Standardized messages are usually longer in length than their non-standard counterparts, so it's a good idea to allow for extra space when allocating msgot within the application program

Parameters

lunit	- Fortran logical unit number for BUFR file
msgin	- BUFR message
lmsgot	- Dimensioned size (in integers) of msgot; used by the subroutine to ensure that it doesn't overflow the msgot array
msgot	- Standardized copy of msgin
