Hi Woody, No problems are known here with regular (2d on surface) reflectivity displays with Level II data. Can you send us the particular file you used, or tell me where to get it, so we can make sure? This may be a matter of your video display. What kind of video card do you have, what memory, and what operating system you are using. How many time steps are you using - try only one to see if that makes a difference. Make sure all the updates or patches for your video driver are applied. Do you see ok displays of reflectivity from Level II data? a note is coming in a moment about your other question. Stu >From: "Woody Roberts" <address@hidden> >Subject: Couple of IDV radar questions >Organization: UCAR/Unidata >Keywords: 200307142109.h6EL9MLd008725 Folks - I successfully downloaded IDV 1.0 and am trying to display some archive Level-II radar data from Melbourne. The Reflectivity 3d option works fine, but I just get a grey image with a few black spots when I use the regular reflectivity option and the same tilt. Are there problems with the regular reflectivity displays for archive Level-II? -- **************************************************************************** Unidata User Support UCAR Unidata Program 303 497 8643 P.O.
