Hi,
I have just downloaded the trail, and before i buy i want to make sure it does i want it to do.

I need this software to do the following.

Download forecast data for europe - GFS data long or short range
Generate forecast charts for europe
upload them to my web server

All in auto

Can this software do this ?

Not automatically. You have to do it all manually. I requested GRIB scripting about 2 years ago.. still nothing

Grib is fine, but a lot of people forget the datasets are huge. Often over 100mb and this usually just kills digital atmosphere and ingesting these would be a large memory hog.

The old ETA 211 domain was fine as these were only around 1 or 2mb in size which DAWS just about handled.

Digital Atmosphere is fine for surface and upper plots/contours from stations obs etc. But in reality the grib side is not worth it being extremely limited.

You would be much better off using PCGridds, or if you have plenty of patience learn how to use GrADS or Gempak.

The small "Eta" 211 files are still available. The following link will expire shortly, but it gives an iidea of the directory structure. Look for the files that end in awp211. cy.00 means the 00Z run (change to 12 for 12Z) and rd.******** is the date, which needs to be changed to the current date if the link doesn't work.

Nice one Pat, I thought NCEP had finished the 211 domain. Still that won`t help Ian who is after European grib.

Ps. Looks like I`ll be tinkering again

Nope, Bob...they've been dinking around with the name of the model alot though (change the eta in the link to nam and it will do the same thing, just a different directory))lol I suppose they kept the eta directory so links would still work...even though the eta no longer exists...if any of that makes any sense to anybody, let me know

Ps I don't know what happened to the WAFS grids for Europe...I don't think these are available anymore for net download. Not saying they aren't available someplace, I just have no idea where to look.

Cheers guys for the help,

Have tried other software, but most will not work on XP, as for GRADS, well its harder to script than this program, does my head in.

NOAA does a degrib program with is really good, although not auto yet, and only covers the US, but will produce forecast images out to 360 h.

While iam here i am trying to learn with scripting with Daws. Could some one just check this script, it runs ok, but produces no data. Its for europe lightning.

erase
download,http://www.atmos.albany.edu/weather/dat ... C:\Program Files\DigitalAtmosphereWS\data\sfuk31.wmo
ingest,C:\Program Files\DigitalAtmosphereWS\data\sfuk31.wmo
product,sf6,plot
stamp
export,C:\Program Files\DigitalAtmosphereWS\maps\lightning_06.gif

i should have problerly post this the scripting page, but any help would be great

Ian,

Your script is great, it just needs the correct link. Try this:

download,http://www.atmos.albany.edu/weather/dat ... C:\Program Files\DigitalAtmosphereWS\data\sfuk31.wmo
ingest,C:\Program Files\DigitalAtmosphereWS\data\sfuk31.wmo
product,sf6,plot

Or this (dependent on the time frame you wish to script, this is the +30 link):

download,http://www.atmos.albany.edu/weather/dat ... C:\Program Files\DigitalAtmosphereWS\data\sfuk31.wmo
ingest,C:\Program Files\DigitalAtmosphereWS\data\sfuk31.wmo
product,sf6,plot

The first sfuk31.wmo will be overwritten through a running of the second script, even though DA WS reads the file, the newly downloaded file is different.

Remember, Ian, DA WS has a built in time token function. Your error was trying to set a time manually....just let DA WS set the time/date for you. This ability is one of the most powerful functions of the software..

To get an idea of how DA WS handles download links...go to the internet retrieval menu...click on text body of what you want to download...click edit....double click on the Enter the URL for this site text window which will hilight it (a blue background)...right click the hilighted text....click on copy from the pop-up menu....open up Windows Notepad...right click the open window and click paste...through this you'll see the whole link DA WS uses to sift through an internet directory using wildcards.
