Function/Subroutine Documentation

compack()

subroutine compack	(	real, dimension(ndpts), intent(in)	fld,
		integer, intent(in)	ndpts,
		integer, intent(in)	idrsnum,
		integer, dimension(*), intent(inout)	idrstmpl,
		character(len=1), dimension(*), intent(out)	cpack,
		integer, intent(out)	lcpack
	)

This subroutine packs up a data field.

It uses a complex packing algorithm as defined in the GRIB2 documention and supports GRIB2 complex packing templates with or without spatial differences (i.e. DRTs 5.2 and 5.3). It also fills in GRIB2 Data Representation Template 5.2 or 5.3 with the appropriate values.

Parameters

[in]	fld	Contains the data values to pack
[in]	ndpts	The number of data values in array fld
[in]	idrsnum	Data Representation Template number 5.N must equal 2 or 3.
[in,out]	idrstmpl	Contains the array of values for Data Representation Template 5.2 or 5.3 (1) = Reference value - ignored on input (2) = Binary Scale Factor (3) = Decimal Scale Factor (7) = Missing value management (8) = Primary missing value (9) = Secondary missing value (17) = Order of Spatial Differencing ( 1 or 2 )
[out]	cpack	The packed data field (character*1 array)
[out]	lcpack	length of packed field cpack.
