[Wrf-users] Topo and land use ASCII - netCDF transformation program

Thu Jun 2 16:37:52 MDT 2011

Hello All Users,

As there was some interest regarding the program to transform ASCII terrain and land-use in WRF format I would like to send  all 3 subroutines to everyone who will need it.
Just follow the instructions below and in 'README'. I working on SGI cluster use as input ASCII file format F7.1 but this is flexible and can be changed in the procedure.
The program is two way and you can check your binary files applying reverse transformation. Please let me know if you improve the transformation procedure.

Good luck and kind regards,
Mikhail

Find attached the program itself 'rd_wr_formatted' (executable and Fortran code) and two C subroutines: to read ('read_geogrid.c') and to write ('write_geogrid.c').
Also I attached README as every computer has its niceties. All additional instructions you will find in 'rd_wr.formatted.f90' itself. The program works with formatted ASCII input files
prepared using Statistica, TextPad or any piece of code. I work on SGI and use Linux Red Hat.

Good luck,
Mikhail

Hi Mikhail,
It is highly appreciated if you could share your program with us. Thanks.
Feng

Hi,

I have a program written on C that transforms any input terrestrial ASCII code file (topo, land-use and so on) in WPS binary format: 'rd_wr_binary.exe'.
It is written on C as Fortran always leaves empty bits between 2 lines that is not appropriate. This program is 2-direction one and can be used to check
binary input terrestrial files transforming them in ASCII code. The program is very flexible and easily can be changed and re-compiled.

Of cause after preparation of our own terrestrial files I create new subdirectory (with tiles) and 'index' file in 'geog' and edit "GEOGRID.TBL" in
' WPS/geogrid/' sub-directory to create several pointers on new terrestrial files and to choose an appropriate' interp_option'.

We use to create our own terrain and land-use files (using special statistical methods and GIS) all the time for fine resolution WRF runs
(1000 - 500m) to study wind resources for different on-shore and off-shore sites. USGS 2m - 30s terrestrial data is too coarse and very often is a crap.

Regards,

Hi,
other option is modify the binary files of some existing landuse (modis or usgs), matlab read and write those files whit almost no problem.

Hamed,

We have done experiments here in the past, where we modified the greeness fraction based on data from polar-orbiting satellites.  We simply modified the geo_em NetCDF file, and it worked well.  You should be able to take the same approach with land use.

Dear All,
I want to change some values of my landuse in order to see how it affects the whole domain. For example,
change part of the landuse to Forest or Lack.
Does anyone know about this issue?
Thanks in advance,
