Hi all
I have to write a report of the chasing days of may 22 (S.Pieter-Hill city supercell)and may 23(Canadian supercell) and I need radar images of those days(even animations if you can). Anyone can help me?
I know there's the link

http://hurricane.ncdc.noaa.gov/pls/plhas/has.dsselect

but I can't download from there.

That's the raw data - load it in GR or whatever radar software you use.

What do you mean with GR?You mean Grlevel softwere?

Yes, the radar data there isn't already in a graphical format. You have to untar the files and load them into radar viewing software. Let me know if you need more details.

Thank you Nick,but I didn't understand what to do yet:) I've got the GRlevel softwere(trial) but when I download the tar file I don't know how to load the file..

In the meanwhile, if anyone has got the radar images in jpeg,he could post'em;)

Hey Andrea,

A friend saved these for me, but it has a bunch of other stuff too on it, if you don't mind.

you have ot download the .tar file and "untar" it... most zip/unzip programs will do this. then you should have a batch of .Z files... load those into GRlevel3

1. Install Digital Atmosphere (weathergraphics.com).
2. Map > Generate > Station: HLC, scale 230 nm.
3. Map > Overlay > Counties > Outlines.
4. Map > Copy Markings To Basemap.
5. File > Preferences > General > Radar Source Override > Texas A&M Archive.
6. Radar > Set NEXRAD Station > KGLD KDDC .
7. Radar > Set Date-Time > uncheck "current", set to May 22, time to 23:00.
8. Radar > Base Reflectivity. You may have to wait a minute if TAMU server is slow. Ouila!

Of course I have a vested interest in the software since I wrote it. It's a lot easier than messing around with NCDC tarballs.

Tim-

I have D.A. installed but my trial period is up so some of the features are disabled. I'm trying to bring up archived radar by following the steps above. The only step I cannot complete is #2.

After skipping that step, I get down to #8 and the data transfers over OK, but it doesn't display any radar data, just a black rectangle in the top left corner and it says "Base Reflexivity 0.5 deg SFC NOERR - Input file not compressed, so it was copied to output!"

Do I need the full version do view archived data?

Tim,do I need the activated softwere or is sufficient to have trial version?
