Build and Install the HDF5-WRF IO Module
There are two HDF5 WRF IO modules, sequential and parallel. The either or both modules can be configured as optional IO modules for WRF.
The sequential HDF module (io_hdf5) uses the serial HDF5 library. The parallel HDF module (io_phdf5) uses parallel HDF5 (which requires MPI-IO).
The installation for the two modules is similar.
Prerequisites
WRF 1.3
The HDF5 WRF IO modules require Version 1.3 of WRF. Information and downloads are available at:

> http://www.mmm.ucar.edu/wrf/users/user_main.html

HDF5-1.6 .2 or later
The HDF5 WRF IO modules require HDF5-1.6.2 or more recent. The parallel HDF5 WRF module requires parallel HDF5 (which requires MPI IO).
Installing HDF5

1. To obtain HDF5, download from to http://hdf.ncsa.uiuc.edu/HDF5/release/obtain5.html. Install HDF5 according to the instructions. The HDF5 library must have he Fortran 90 interface installed.
   For the sequential WRF module, SZIP compression can be enabled.
2. For the parallel WRF module, parallel HDF5 must be installed (this requires MPI-IO).
   Set the environment variable PHDF5 = <<path where phdf5 is installed>>.
3. For the sequential HDF WRF IO module, either serial or parallel HDF must be installed.
   The HDF library may be installed with the optional SZIP compression enabled.
   Set the environment variable HDF5 = <<path where hdf5 is installed>>.

Platforms

This prototype has been tested on a few platforms. The HDF WRF IO modules should work on any platform that WRF3.1 and HDF5 support, although the details of the configuration may need to be worked out.

Module | Platforms | Notes
Sequential | NCSA IBM P690. NCAR IBM SP3 PC Linux with PGI Fortran 90 Compiler, Vers. 4 SGI IRIX6.5-64 bit | To date, WRF3.1 does not work on Linux with PGF, version 5.
Parallel | NCSA IBM P690. NCAR IBM SP3 |

Installation of the HDF5 WRF IO Modules
The HDF5 WRF IO modules are used by adding it to a standard WRF configuration. This process has four main steps

1. Downoad the HDF WRF IO module(s)
2. Add the HDF5 WRF IO module(s) as an "extern" module
3. Modifying relevant files in the WRF distribution
4. Compile WRF following the usual procedures

The parallel, sequential, or both may be configured.
1. Download the WRD-HDF5 IO modules
The HDF WRF IO modules are available from:

- sequential: ftp://ftp.ncsa.uiuc.edu/HDF/pub/outgoing/wrf-hdf5-modules/io_hdf5.tar
- parallel: ftp://ftp.ncsa.uiuc.edu/HDF/pub/outgoing/wrf-hdf5-modules/io_phdf5.tar

2. Add WRF-HDF5 IO module(s) to the WRF source

The HDF5 WRF IO modules are added as sub-directories in the 'external' directory of the WRF source.

> > cd external;
> > tar xvf io_hdf5.tar
> > tar xvf io_phdf5.tar

contents of the sequential HDF WRF IO module: ./io_hdf5 ./io_hdf5/wrf-hdf5.F90 ./io_hdf5/wrf_status_codes.h ./io_hdf5/Makefile ./io_hdf5/wrf-hdf5attr.F90 ./io_hdf5/wrf-hdf5support.F90 ./io_hdf5/wrf_io_flags.h

contents of the sequential HDF WRF IO module: ./io_phdf5/ ./io_phdf5/Makefile ./io_phdf5/wrf_status_codes.h ./io_phdf5/wrf-phdf5attr.F90 ./io_phdf5/wrf-phdf5support.F90 ./io_phdf5/wrf_io_flags.h ./io_phdf5/wrf-phdf5.F90

Design note:

In the sequential HDF5 WRF IO modules, arrays larger thatn 8096 bytes are compressed by default. In this case, the HDF5 dataset is configured to use the shuffle filter plus deflate (GZIP) compression, with compression level 6.

In the current prototype, there is no option in the namelist for users to change this default. To modify this behavior, it is necessary to modify the source code.
To disable compression:

> Edit the file 'wrf/external/io_hdf5/wrf-hdf5.F90'

> Comment out the lines:

> call h5pset_shuffle_f(crp_list,hdf5err)

> and

> call h5pset_deflate_f(crp_list,6,hdf5err)

To use SZIP compression instead:

> For SZIP information and downloads, see the szip at http://hdf.ncsa.uiuc.edu/doc_resource/SZIP/.

> Edit the file 'wrf/external/io_hdf5/wrf-hdf5.F90'.

> Comment out the lines:

> call h5pset_shuffle_f(crp_list,hdf5err)

> and

> call h5pset_deflate_f(crp_list,6,hdf5err)

> Uncomment the line:

> call h5pset_szip_f(crp_list,H5_SZIP_AK13_OM_F+H5_SZIP_NN_OM_F,8,hdf5err)

> Change the value of the parameters in the function h5pset_szip_f if necessary. See the SZIP documentation for more information about the parameters.

3. Modifications to WRF files

In order to add a new IO module to WRF, several files in the WRF source code must be changed. The following files need to be modified:

WRFV1/configure WRFV1/Registry/Registry WRFV1/arch/Config.pl WRFV1/arch/configure.defaults WRFV1/frame/md_calls.m4 WRFV1/frame/module_io.F WRFV1/share/module_io_wrf.F WRFV1/external/Makefile

The exact changes depend on how WRF has been configured on the sytsem.

Examples of the changes to the files of the WRF1.3 distribution are available at:

ftp://ftp.ncsa.uiuc.edu/HDF/pub/outgoing/wrf-hdf5-modules

WRF configuration files

The 'configure' file must be updated to add the HDF5 and PHDF5 variables.

Modifications of source code inside WRF

The io_hdf5 and/or io_phdf5 modules must be added to the WRF source. In addition, the WRF source must be modified in a few places.

The 'frame/md_calls.m4' must be modified to recognize the HDF modules.
