! FOTRAN 90 Implementation: bufr_expanded
!
! Description: how to read all the exapanded data values from BUFR messages.
!
!
program bufr_expanded
use eccodes
implicit none
integer :: ifile
integer :: iret
integer :: ibufr
integer :: i
integer :: count=0
integer(kind=4) :: numberOfValues
real(kind=8), dimension(:), allocatable :: values
call codes_open_file(ifile,'../../data/bufr/syno_1.bufr','r')
! the first bufr message is loaded from file
! ibufr is the bufr id to be used in subsequent calls
call codes_bufr_new_from_file(ifile,ibufr,iret)
do while (iret/=CODES_END_OF_FILE)
! get and print some keys form the BUFR header
write(*,*) 'message: ',count
! we need to instruct ecCodes to expand all the descriptors
! i.e. unpack the data values
call codes_set(ibufr,"unpack",1);
! get the size of the values array
call codes_get_size(ibufr,"numericValues",numberOfValues)
print*, ' number of exapanded values:', numberOfValues
! allocate array for data values
allocate(values(numberOfValues), stat=iret)
! get the exapanded data values
call grib_get(ibufr,'numericValues',values)
do i=1,numberOfValues
write(*,*) ' ',i,values(i)
enddo
! release the bufr message
call codes_release(ibufr)
! load the next bufr message
call codes_bufr_new_from_file(ifile,ibufr,iret)
! free array
deallocate(values)
count=count+1
end do
! close file
call codes_close_file(ifile)
