FORTRAN 90 Implementation: bufr_get_string_array ! ! Description: how to get an array of strings from a BUFR message. program bufr_get_string_array use eccodes implicit none integer :: ifile integer :: iret,i,n integer :: ibufr integer :: strsize integer, parameter :: max_strsize = 20 character(len=max_strsize) , dimension(:),allocatable :: stationOrSiteName call codes_open_file(ifile,'../../data/bufr/pgps_110.bufr','r') call codes_bufr_new_from_file(ifile,ibufr,iret) ! Unpack the data values call codes_set(ibufr,'unpack',1) ! Get the width of the strings which is the same for all of them call codes_get(ibufr,'stationOrSiteName->width',strsize) ! The width is given in bits strsize=strsize/8 ! max_strsize has to be set to a value >= to the size of the strings that we are getting ! back from the call to codes_get_string_array if (strsize > max_strsize) then print *,'stationOrSiteName array dimension is ',max_strsize,' and should be ',strsize call exit(1) end if ! Allocating the array of strings to be passed to codes_get_string_array is mandatory call codes_get_size(ibufr,'stationOrSiteName',n) allocate(stationOrSiteName(n)) ! Passing an array of strings stationOrSiteName which must be allocated beforehand call codes_get_string_array(ibufr,'stationOrSiteName',stationOrSiteName) do i=1,n write(*,'(A)')trim(stationOrSiteName(i)) end do ! Remember to deallocate deallocate(stationOrSiteName) ! Release memory associated with bufr handle ! ibufr won't be accessible after this call codes_release(ibufr) ! Close file call codes_close_file(ifile) end program bufr_get_string_array
