The only way is to create a model field that contains Z values
and use it in your type-in expressions.  You might write an
external analysis function that creates a Z field.

Dear Vis5d users, 

I would like to invoke the height, Z, in a type-in expression
to define a new-variable (combining it with some other tracers shown explicitly 
on the Vis5d Control Panel).  Is there anyway to do this 
easily or will I have to write a user analysis function?

Thanks,

Dear Vis5d users, 

I am interested in using Vis5d on my 
computer running NT, but am having 
trouble installing it and configuring 
my X windows. Are there any NT 
users out there that could help me ? 

Thank you, in advance.

I have done a couple simulations of the wind flow around the Ross Island 
region in Antarctica using the University of Wisconsin-Madison 
NonHydrostatic Modeling System (UW-NMS).  Vis5d files were created from the 
output from the model.

The Byrd Polar Research Group at Ohio State University has done a fair 
amount of modeling of Antarctica using MM5, but I do not think they have 
used vis5d for model output.

Mark Seefeldt

Dear all,
does anyone know something about simulations with non-hydrostatic models
(such as RAMS or MM5) visualized
with vis5d? 
Thank you for any suggestion.

Dear  Vis5D users:

Hi!  I am trying to customize, using a TCL script, Vis5D environment in
displaying anomaly variables.

Using TCL commands such as "vis5d_set_hslice", and "vis5d_set_vslice",
I was able to define the low/high limits for contouring.  However, the
color counterparts to these, that are "vis5d_set_chslice" and
"vis5d_set_cvslice", do not allow me to define the low/high limit.  It's
very important for me to define low/high limits for color slices, and
yet I don't know how to achieve this.

Does anybody have any idea?

Thank you.

Good Day:
 I'm having trouble compiling the library libnetcdf.a that is needed to
compile vis5d...
 Basically, the configure script fails to find a file called conftest.o
during the configuring proccess
I compiled it by hand using fort77 on HP-UX 10.2 on a J5000 workstation,
and then the configure
process seemed to work.  So I ran the makefile.  But, none of the files
that the makefile tries to
compile seem to recognize <errno.h> even though it's already included.
Do you have any suggestions?

This sounds like an excellent idea.  There are many different
GRIB to Vis5D converters, and having a common effort will be
a big benefit.

I should also say that I am very happy with Steven Johnson's
Vis5d+ project on SourceForge.

Bob,

Vis5d has a limited capacity to overlay NWS sfc obs which are written in the NetCDF format used by NOAA FSL.  You may be able to get the data already in that format since it is now used in the new AWIPS system of the NWS,  otherwise
you would need to convert whatever data you have.   As I said above, the ability of Vis5d to display this data is limited.  It will allow you to select one field (Temperature,  MSL pressure,  dewpoint, whatever) and print the text
value of that field at the station locations.  It will allow you to change the density and font size of the plots so that you can make it readable independent of the scale you are using.    There is nothing currently available in
vis5d to plot ua observations.   There may be a modified vis5d out there to do what you need, if you find it, please let me know.

I have plans to extend vis5d+  (http://vis5d.sourceforge.net) to allow a limited station plot to be drawn, but I haven't gotten around to it yet.    If you are interested in collaborating on such a project drop me a note.

Mr. Cameron,
  What version of MM5, and what platform?  I wrote a converter program for
MM5 version 3, on an AIX system.  It's written in F90 and pretty generic in
nature, so the type of data being used shouldn't matter.

Let me know if you'd like more info on it.

Dear  Vis5D users,

Hi!  I tried to use Vis5D with "TCL"  in my Linux PC.  It appears that the key is
to get TCL 7.4 library for Linux.  I downloaded the source code for TCL 7.4 and
somehow couldn't compile it on my Linux PC.  Is there anybody who has any helpful
ideas or who has Linux-compiled TCL 7.4 library?

For information, linking Vis5D with TCL 8.3 (as I successfully compiled TCL 8.3 on
my RedHat Linux PC) produces Vis5D executable, which does not support TCL script
normally.    Also, I downloaded the pre-compiled Linux version Vis5D, which showed
the same problem.  On the other hand, compiling Vis5D without TCL does not do at
all anything related to TCL.

Hi Lisa,

A gamma correction hack should go in src/graphics.ogl.c,
perhaps in make_big_window() or make_3d_window().  I have
no plans to do this, but perhaps someone with Solaris 8
and Elite3D will.

We are trying to set up a terminal server with Vis5d on an NT Box.  I have
only installed NT on this box and when I read the instructions for the NT port
it mentioned we needed an X-server.  I ordered Kea X from Attachmate, then
after fighting with the configuration for two days decided to write for help. 
I just have a couple of quick questions.

1.  Can I run Vis5d (NT Port) on a terminal server?

2.  Do I need an X-server?

3.  How do I configure the x-server to run an NT program?

ANY help you could provide would be greatly appreciated.  Thank you.

Will Morris

I have encountered a problem where the colors are "dimmed" in vis5d when using
it on an Ultra 80 running Solaris 8.  I had the same problem with xv, but found 
a patch for xv which took care of this.  I might be able to wade through all the
code and look for the similarities, but I was wondering if there is a similar
patch for vis5d.

The problem exists due to Sun providing two identical Visuals with different 
gamma correction curves, for different types of hardware.  Before I patched
the problems with OpenGL and the Elite 3D graphics then the colors were correct.
I can't get Sun to tell me outright what those changes were in the patches that
now keep the system from crashing which is critical.

Thanks,
Lisa

I am now downloading Dragon Linux for use on Vis5D. If this is a mistake
please let me know because there are so many types of linux in this
world I just chose one that would work with windows and DOS.

I know there have been models run to make a supercell. So does anybody know if
and where I can get data like that for Vis5D? I haven't even tried to use the
program yet because I would have to use linix and I don't know if I can because
I want windows too.

Michael:

Since 1997 NCEP/EMC produce Vis5D files of the
NCEP models on a timely basis for a number of
preset areas and variables.  While this is done for
my own account, there is no restriction on public use of these
files.  You may find access to them on the web page:

http://sgi62.wwb.noaa.gov:8080/research/vis5d.html

The Vis5D files are created automatically and unattended.
A short (rotating) archive is maintained for each of the
entries.   For example, the Medium Range Model (run once
a day at 00Z) over an area containing North America
maintains the last 4 cycles (days) of runs and the most
recent.  2 of the 4 Eta run cycles are available per day
going back for three days (6 model runs).  The   date/cycle is
part of the Vis5d file name.

The ensembles (of many model integration's) are Vis5D
files with the vertical coordinate as the ith component of the
ensemble run instead of elevation, z.  One can use vis5d
to sweep through all the ensembles at any time or look
at Vis5D Iso-surfaces which give weather event probability
for user selected events.

There are contributions from the operational (and other)
regional RUC, Eta, NGM and the Global models
as well as some reruns of special cases,
for example, the Storm of the Century:

http://sgi62.wwb.noaa.gov:8080/JAEMC1/eta_century/CEN_ETA930212.v5d

A Pacific Typhoon:
http://sgi62.wwb.noaa.gov:8080/JAEMC1/paka/PAKA_971210.v5d

The Perfect Storm
 http://sgi62.wwb.noaa.gov:8080/JASGI100/gemvis/perfect_storm/PRSTM1027.v5d

There are also difference files like forecast error and and differences
between experiments and operational runs.

These files use GEMVIS (available on the same Vis5d web site)
which links with GEMPAK (see the Link to the Unidata site) to
conveniently create the Vis5D files from the model run history
(GRIB) files.  The Vis5D files typically contain the standard run
history elements of T, RH, moisture, TD, U, V, W, (for the skew-T)
Vort., Div. and a number of advective quantities such as vorticity,
moisture, temperature and many 2-D fields such as PRCP
(convective and large scale) surface T, and precip water.
I have tried to keep the file size range between 10-50Mb.

The process of improving our ensembles, reconnecting
the 10km Hawaii run and other systems turned off when
NCEP switched computers are where things stand now.

With Vis5D grids, the x, y and z values are always implicit, so
you can't do anything with your ASCII x, y, z values.  Your only
freedom with them is to pick a map projection (e.g., Lambert
conformal or polar stereo).  You will have 3-D grids for your
U and V variables, with grid indices ir, ic and il (for rows,
columns and levels).  Sort of two grids of the form G(ir, ic, il).
As in foo_to_v5d.c, you loop over grids for time steps and for
variables.

Cheers,
Bill

Hi Vis5d list,

Im about to give getting some wind vector data into vis5d a go. Im brand
new to the program and have been reading the README, foo_to_v5d.c and
other docs. 

I have ascii text xyz values for a regular single level grid, I also
have u and v values representing components of wind vectors for every
xyz or grid point. 

Reading the docmentation, it appears that the xyz values will be read in
the for loop at step 3. If I declare variables for u and v, and I have
values for every point, how should those values be represented?.

I kind of need an array like G(ir, ic, il, iu, iv)

Or is there some other way I should be tackling this? I didnt fancy
irregular data formats for a pile of vectors, it seemed a bit
uneccessary.

Any ideas, ...very appreciated
