这是子程序部分 subroutine readcmfd(ix,jx,iyear,imon,nmstep,dir,cmfd) !fang implicit none character(len=256),intent(in) :: dir integer, intent(in) :: ix,jx integer, intent(in) :: iyear,imon integer, intent(in) :: nmstep real, intent(out),dimension(ix,jx,248,7) :: cmfd integer :: i,j,itm,ivar integer, parameter :: nvar = 7 real, allocatable, dimension(:,:,  :: varinclude 'netcdf.inc' CHARACTER(len=256) :: ncfile CHARACTER(len=12) :: varname(nvar) INTEGER STATUS INTEGER NCIDin INTEGER varID INTEGER START(3), COUNT(3) data (varname(ivar), ivar=1,nvar) & /'temp','shum','wind','pres', & 'prec','srad','lrad'/ allocate( var (ix,jx,nmstep) ) START(1) = 1 START(2) = 1 START(3) = 1 COUNT(1) = IX COUNT(2) = JX COUNT(3) = NMSTEP do ivar=1,7 do itm=1,NMSTEP do J=1,JX do I=1,IX CMFD(i,j,itm,ivar) = -999. end do end do end do end do write(*,*) '-------------------------------------------' do ivar = 1, nvar write(*,*) varname(ivar) !write(*,'(I4.4,I2.2)') iyear,imon write(ncfile,100) iyear,varname(ivar),iyear,imon ncfile = TRIM(DIR)//ncfile write(*,*) 'READFORC: opening ',trim(ncfile) STATUS=NF_OPEN(ncfile,NF_NOWRITE,NCIDin) IF (STATUS .NE.
