Hi I have noticed that since 12z 27/May that the noaa server has been having issues and as a result opengrads scripts are not updating.

1: if for example you look at http://nomads.ncep.noaa.gov:9090/dods/gfs_0p25/gfs20180528/gfs_0p25_18z.das it may display the correct data, though if you refresh browser it will result in:

Error {
    code = 0;
    message = "extraction failed; not enough lat data in /tomcat_cache/gds/grads/dods/gfs_0p25/gfs20180528/gfs_0p25_18z.lat.output";
};

Then do the same again again : may result in:

Error {
    code = 0;
    message = "/gfs_0p25/gfs20180528/gfs_0p25_18z is not an available dataset";
};

I assume when opengrads script hit these issues they crash.

I also wonder if this impact any of the WxSim data imports. prior to Chris/Sam’s process’s

I see that other sites not just mine are showing old maps : https://silveracorn.nz/weather/wxgfs_slp10mw.php and http://www.leavening.org/gfs/ as a couple of examples.

Any one know anything about this ?

Kind regards,

So, after all the pain in getting these scripts working, I noticed last week that it all stopped and my images are now out of date.

A quick look at the Nomads site appears to say that they moved to a secure server so it

Hi,

if you are using OpenGrADS under WIN, you have to wait for the new version, which supports ssl (https) communication.

They are working on it.

Marian

Ah! I am using windoze. Thank you. How annoying, I wonder how long it will take?

I tried grabbing the files with wget so I could process them locally without having to use https in OpenGrads but that also failed. I wonder if I

The new OpenGrADS is out:

Hi Marian,
Long Speak no Time.
Would I be Correct/Wrong in assuming that the new version of OpenGrads would require Minor/Major changes to our existing .gs scripts.
Kind Regards,
Hope you are well, Tony

Thnx. I saw this yesterday but am having problems updating GrADS.

Both the .gz and the Windows Superpack are missing the grads.exe executable.

Obviously it

I downloaded the new Superpack this morning and installed it. My modified version of Nordic.gs works but the background and legend colours are not right yet. I will have a further play today.

Chris

Hi Chris,

Did you install over existing install? I definitely have no exes in my install?

Regards, Simon

Simon,
I simply saved my scripts (and cbarm - in OpenGrADS/Contents/Resources), uninstalled OpenGrADS and then downloaded the superpack from Sourceforge using the link from Marian. I then reinstalled the missing files and all seemed to work.

I do have issues - the legends are all in white as opposed the original black. I will edit my Nordic.gs script to correct them, but I suspect that there must me a simpler solution.

Chris

Hi I did same as Chris with same result.
So did a fix (possibly not correct) but it worked for me.

In the " while ( i<maps ) " section prior to " ‘set gxout shaded’ " I added " ‘set display color white’ " as per image below, will not attach my scripts as they are modified for Aus.

Kind regards,


Tony,
Many thanks. ‘set display color white’ was the fix I was looking for.

Chris


Finally got the images produced and correctly coloured thanks to the white background tip posted here.

Does anybody have a script for aninatingvthem which they could share? Mine has ceased to work and I can

Hi Simon,

looks like you have " while ( $map <= 64) " set to 64 and you only have 57 "

  • |
  • "
    I found 61 "
  • |
  • " and " while ( $map <= 61) " seems to work, though you may need to adjust some table sizes etc.
    Or maybe even in addition, change :
    From :
    #nav li { float: left; margin: 2px; list-style: none }”
    To:
    #nav li { float: left; margin: 1.5px; list-style: none }”

    regards,


    Thanks Tony. It seems to be working now …

    Seems as though our Opengrads GFS Precip Maps have another issue since the recent GFS changeover as of 12z 20190612.
    APCP seems the cause, in our scripts we use the following (which does not seem to have changed) however what I see on not only mine but also Brian’s (SilverAcorn-NZ) and Chris’s (Tayside-UK) is that it seems to accumulate over time. Look out to your last generated map (I generate 79 maps so go out a far way).

    acpcpsfc
    ** surface convective precipitation [kg/m^2]

    apcpsfc
    ** surface total precipitation [kg/m^2]

    I have searched, though not found a resolve, if anyone has any ideas, please share,

    kind Regards,


    Hi,
    Just Bumping this again, I take it nobody has found a resolve for this issue as yet.
    Kind Regards,

    I know this will be a dumb question but I can’t seem to find the answer in documentation or the post…

    How do I change units? I’m in America, so I need F, MPH, etc.

    I’m still struggling to find an answer, even after googling for a while…
