Hi Support,

We are new to ARPS and would like to use the radar and satellite data as received in Hong Kong into ARPS.  It is noted that ARPS is prepared to use the data of the following formats:

Radar - level III for NEXRAD and level II for 88D

Satellite - MCI raw satellite data

However, these formats are not used in Hong Kong, and we think we need to format our radar and satellite data into the above formats.  Would you please help locate the documents descrbing these file formats?

Hope to have your soon reply.  Thank you very much!

Regards,

It would be a lot of trouble trying to understand and write the Level II
format. 

Actually, all you need is to fill the radar data arrays (3d in
radial, azimuth and elevation) in our program 88d2arps, and provide the 
necessary radar parameters. We have recently added a new program based on 
88d2arps which reads radar data in NetCDF format (called ncrad2arps.f90
in src/88d2arps).  Program nids2arps processes Level III 88d data for ARPS. 

So if you know how to read your radar data, you can link the reader to one
of these programs.

Keith Brewster and Yunheng Wang can provide you/point you to more details.

Hi Dr. Xue,

Thank you very much for the prompt reply.

Grateful if we could get a sample netcdf radar data file so that we could 
format our radar data towards it.  Could such a file be provided to us? 
Thanks.

Regards,

P.W. Chan

Mr. Chan,

Which satellite and radar data do you have?

We have recently developed code for operational Chinese radar and
geostationary satellite data for other users, by developing readers for
those codes that replace the readers for the data formats that you named.

Dear Dr. Brewster,

Thank you for your reply.  Though Hong Kong is part of China now, we are 
using completely different radar and satellite systems from the mainland 
China for historical reasons.  For radar, we have data in IRIS format.  For 
satellite, we have data in S-VISSR for geostationary satellites launched by 
China and HRIT for the Japanese geostationary satellites.  Could these data 
formats be used in ARPS?

Otherwise, say for radar, we would need a sample netcdf file so that we have 
to write our own code to convert our IRIS data format into netcdf in an 
appropriate way.

Thanks a lot.  Look forward to your advice.

Regards,

We have code to read and process the Chinese VISSR data in hdf5 format.

The McIDAS AREA file is a popular format and there may be a converter for
the HRIT data to McIDAS AREA file.  McIDAS is a University of Wisconsin
product and you may find information there about their format.  As Ming Xue
mentioned, we have found that it is often easier to just replace the I/O
part of the code with I/O appropriate for your format.  The provider of your
satellite data might be able to help with that.

Separately I will send a sample radar data file (gzip compressed) that you
can use as a template to convert the SIGMET data.  We have investigated the
SIGMET software, but to date, we have not had support or free time to pursue
writing I/O interface for SIGMET formatted radar data.

You can look at the file structure using the ncdump command that comes in
the NetCDF release.  Using "ncdump -h file_name"  will show the headers and
data structures without the voluminous data.  Note that there are some
variables and attributes in the file that we do not use (this sample is
dual-pol), see the code for ncrad2arps to see which variables are currently
used.  In the near future we will expand to use the dual-pol data, but it
will not be required information.

Hope that helps,
-Keith

Dear Dr. Brewster,

If I have not mistaken your point, the code that you provide is the 
conversion of satellite data in hdf5 format into arps format.  Do you have 
code of the conversion from VISSR format to hdf5 format?  Thanks for your 
help.

P.W. Chan

Dear all,

On a separate subject, it turns out that we have Japanese satellite data in 
hdf4 format.  Is there a converter for hdf4 into arps format?

Thank you.

Message-ID: <HHEIJOJABICFEFAGHOHFEENKCKAA.leanderson@cefet-rj.br>

Dear friends,
I have done some test runs using arps5.2.8 that I download from ARPS page. I
learned to run ARPS using arsintrp to do one-way nesting. But now, I would
like to do two-way nesting runs. I read something about arpsagr, however I
don't find any README, namelist.input, and others, explaining how can I run
on two-way. So then, does anybody could me give the steps to execute a
two-way run, using, for example, 2 or 3 grids nesting?
Thanks. Bye bye.

Dear all,

Hope to get your advice on one thing.

We would like to carry out high resolution (with delta x ~ 200 m) numerical 
simulation for Hong Kong to study terrain-induced airflow disturbances.  As 
such, we would need to input the high-resolution (delta x ~ 90 to 100 m) 
terrain and surface information for Hong Kong, instead of using the standard 
USGS data for the whole globe.  How could this be done?

Look forward to your advice.  Thank you!

We would like to use the Shuttle Radar Topography Mission (SRTM) data 
(3-arc-second data) for the globe in ARPS, in particular for areas around 
Hong Kong.  Does anyone know how this can be done?

Look forward to your advice!

You can modify program ARPSTRN to prepare terrain data set for the ARPS 
system. Actually, the current code for ARPSTRN already processes 3 
seconds data for the continent of United Statue and Europe. You can make 
minor modifications based on the current code for Hong Kong.

Please check instructions in file input/arpstrn.input first. The source 
code is in directory src/arpstrn/arpstrn.f90.

You need to modify arpstrn program to read in your data set. 

It already has an option to read 3 arc second data for the U.S. region
(stored in patches).

Just modify the reader to feed the arrays the right data.

arpstrn code should be self explanatory.

For the 12km NAM data, we distinguish the following two scenarios:

1. If the data are in several individual tiles (9x6), use extdopt =16;
2. if the data is in one large file, use extdopt = 116;

Please check instruction in file input/arps.input for extdopt for more
detail before running ext2arps.

Dear all,

We would like to use some real data for a sample run.  The real data 
includes surface obs, upper air obs and the grib data of an external model 
(e.g. GFS).  Where could we get the data for test-run our version of ARPS, 
just to make sure that the ARPS has been configured successfully in our 
workstation?

Hi Dr. Wang,

Thank you.  We are still downloading the data.25may1998 file.  Just wonder 
if this file contains grib data for a try?  If not, where could we get the 
appropriate grib files for a try?

Regards,

Subject: [ARPSSUPPORT] ext2arps question
Message-ID: <4850931F.9060106@student.canterbury.ac.nz>

Hi,

I am trying to initialize my simulation from gfs grib2 files using 
ext2arps. I compiled ext2arps without jasper and png libraries and it is 
working fine with grib 1 data like fnl files. For grib 2 format I 
selected extdopt=20 and initialized using one gfs file as a start but 
the program stopped saying that "ARPS domain extends beyond the 
available external data", which is not the case ofcourse. When looking 
at the ext2arps output file I realized that all the extracted fields 
where either 0 or 999, see attached file for output. I also renamed the 
gfs file as required "gfs.2008060800f00". Attached is the output and 
input  file, can you please tell me if I am doing something wrong in that.

Thanks

jasper and png are required because GFS data is compressed using either 
of them. Furthermore, they are usually standard libraries within Linux 
system. If they are not part of your Linux system, you can always 
download them for free by following the instruction in 
src/external/g2lib/README.doc.

First, thanks for searching first. I am CC'ing to ARPSSUPPORT for
archiving purpose.

You should do the following.

1. Download HDF 4.2 source code and compile it with option
"--disable-netcdf";
2. Compile arpscvt with option "-io nethdf";
3. Run arpscvt from HDF format to netCDF format.

Cheers.

Hi,

I downloaded the new version of ARPS earlier today (5.2.9) and I am trying to use the new casa2arps functions. I thought you might want to know that in the docs/casa2arpsppi.pdf it says that to compile you need to type ./makearps casa2arpsppi but if you do this then you get an error, I think to compile it just needs to be ./makearps casa2arps.

Thanks,

Charlotte Wainwright.

Just set ovrobs=1 and specify the lso file.
It must be slice_xy=2 and a variable that is observed (temperature, wind,
dew pt, etc)

What is the issue?

Hi, all,
Did someone know how to use the function of arpsplot to overlay sfc
observation on the corresponding forecast fields?
I tried for some time and failed.  If some one has an example input and send
it to me, that will be appreciated so deeply:).

Hi ,

We are planning to install ARPS in operational forecasting for New 
Zealand on our 2-rack Blue Gene IBM computer total 4096 cores and would 
like to know if there was a previous known attempt to do that, or 
something similar? If you have any suspected problems that we should be 
aware of we'll be grateful to receive them. The intent is basically to 
run ARPS on 128 or 512 processors. I have understood that it is working 
fine on the Pentium III Linux clusters and the Compaq Alpha clusters. Do 
you have any recommendation that might be helpful for us?

Thanks

I have heard that several institutes from Europe and Asia have been 
using ARPS as an operational model. We also tested the model and its 
accessories during the Spring real-time experiments on a Linux cluster 
locally.

I do not have first-hand experiment on IBM Blue Gene, but as long as you 
compile the programs successfully, they should be no difficult to run it 
than on Linux cluster. I would like to help you with anything possible 
for a successful compilation (script makearps & Makefile).

Please feel free to contact ARPSSUPPORT at ou.edu with questions and report 
your success.

BTW, we just released arps5.2.9 a few days ago. Please use this version 
and many accessorial programs have been parallelized, especially 
arps3dvar, adas etc.

Yunheng Wang.

Dear ARPS support,
 

Do you know of any changes to the KBOX and KBGM radars that may have taken place? Neither of these radars have successfully run through the 88d2arps remapper since June 10th (KBOX) and 11th (KBGM). I am getting the following error message at the end from the 88d2arps program:

 

Finding range of mean profile data ...

 z =   19000.00 knt =     0. accept =      2761.

 z =   18904.52 knt =  9204. accept =      2761.

 Height of data for wind profile spans from      95.48 to   18904.52 meters.

 Back from extenvprf

 Retrieved reflectivity index as 0

 Retrieved velocity index as 1

 Retrieved spectrum width index as 2

 Read_radial returned double eof

 20 bad read status reports received

 

Perhaps you can help me decipher the error messages...

 

Thanks much!

Jonathan Case

Radar format was upgraded recently (I do not remember the exact date). 
ARPS 5.29 was released a few days ago, which includes decoder for the 
new data format.

Dear ARPS support,
 
Here is what happened after upgrading to arps5.2.9 for 88d2arps.  All radars process correctly except Boston (KBOX).  Please see the output below.
 
Thanks for the feedback,
Jon Case

I tried newer version of 88d2arps and it did process all the radars successfully - except for the KBOX radar. Here is the end of the log file:

 

Calling extenvprf2

  iradar =           258  jradar =           174

  ibeg =           203  iend=           279

  jbeg =           119  jend=           229

 

  extenvprf: found   6885 points within radius

  of   8547 checked.

 

 Finding range of mean profile data ...

 z =   19000.00 knt =     0. accept =      2066.

 z =   18904.52 knt =  6885. accept =      2066.

 Height of data for wind profile spans from      95.48 to   18904.52 meters.

 Retrieved reflectivity index as 0

 Retrieved velocity index as 1

 Retrieved spectrum width index as 2

 Clear-air VCP detected: 32 Exiting.

 Normal termination of 88d2arps.

 

So, as you can see the program terminated normally, but there is something else wrong with the data. Any ideas? I switched the scripts to use the new 88d2arps program so the next run should use this version. However, I noticed that we are not getting radar data right now.

Leela,

 

I should think that a new version ought to be a superset to be able to support older radar formats as well.

We shall see!

Leela,

 

It sounds like we ought to obtain arps5.2.9 to compile 88d2arps and follow Keith's instructions below.  That might be easier than trying to obtain the latest a2io library and such as described below.

 

If that works, you could probably just run 88d2arps only from 5.2.9 and all other programs from 5.2.8.

 

Jon

Have these radars converted to NEXRAD Build-10, super-resolution data?

We have a new version of a2io for this.  I believe it is now in the public
version of arps5.2.9 -- probably can get away with changing to new a2io
library and adjust the max radials in 88d2arps (to 800) without doing a
complete update to arps5.2.9, but you might compare 88d2arps.c versions of
each.

I am currently at a meeting in Europe.  Kevin Thomas is on vacation for a
few weeks.  Yunheng can help set you up.

There is a feature to terminate 88d2arps in advance if clear VCP is 
found. It is a feature desired for 2008 CAPS real-time experiments.

You can turn it off by commenting out several lines in file 
src/88d2arps/88d2arps.c to get identical result as before. Please search

"QUICK FIX for RT-2008" in about line 1486.

The message is already very clear about the problem, i.e. no enough
memory for your run. I have highlight it with red below. It seems that
your namelist file is either not right or did not read in correctly. So
undetermined values are used for allocating arrays. They may be very
large numbers so that the allocation failed.

Ranger indeed does not read in namelist file right occasionally. It
should be reported to TACC or Teragrid support staffs. If you submit the
same job script multiple time, there may be one success. Anyway, I will
encourage you to report. More reports will cause their attention to the
problem.
