WRF-VAR
This file is in ASCII format and so you can easily view it. To have a graphical view
about the content of this file, there is a “MAP_plot” utility to look at the data distribution
for each type of observations. To use this utility, proceed as follows.
> cd MAP_plot
> make
We have prepared some configure.user.ibm/linux/mac/… files for some platforms,
when “make” is typed, the Makefile will use one of them to determine the compiler and
compiler option. Please modify the Makefile and configure.user.xxx to accommodate
the complier on your platform. Successful compilation will produce Map.exe.
Note: The successful compilation of Map.exe requires pre-installed NCARG Graphics
libraries under $(NCARG_ROOT)/lib.
Modify the script Map.csh to set the time window and full path of input observation file
(obs_gts_2008-02-05_12:00:00.3DVAR). You will need to set the following strings in
this script as follows:
Next, type
Map_plot = /users/noname/WRFDA/var/obsproc/MAP_plot
TIME_WINDOW_MIN = ‘2008020511’
TIME_ANALYSIS = ‘2008020512’
TIME_WINDOW_MAX = ‘2008020513’
OBSDATA = ../obs_gts_2008-02-05_12:00:00.3DVAR
> Map.csh
When the job has completed, you will have a gmeta file gmeta.{analysis_time} corresponding
to analysis_time=2008020512. This contains plots of data distribution for
each type of observations contained in the OBS data file: obs_gts_2008-02-
05_12:00:00.3DVAR. To view this, type
> idt gmeta.2008020512
It will display (panel by panel) geographical distribution of various types of data. Following
is the geographic distribution of “sonde” observations for this case.
