Over the last few days, I've been working >on the installation of McIDAS 2004 here at CCNY. The >installation was completed yesterday, and McIDAS 2004 >appears to be running smoothly so far. Sounds good! > As I tried out McIDAS 2004 yesterday, I attempted to >load a series of images using the IMGDISP command. What I >wanted to do was to display a loop of all the available >images within a specific hour. It appeared to me that the >ALL keyword of the IMGDISP command should do the job. The >command line I entered was > >IMGDISP NEXRCOMP/1KN0R-NAT 1 DAY=04/08/11 TIM=17:00 17:59 >ALL=1 12 EU=BREF24 LAT=40 78 > >I soon found out that this command does not work for some >hours, in which cases an error message saying "No images >satisfy the selection criteria" was shown. I later found >out that the reason the command did not work for these >hours was because there were missing image(s) so that >there was a total of less than 12 images within those >hours. I just ran the following command successfully: IMGDISP NEXRCOMP/1KN0R-FLT ALL=1 50 EU=BREF24 SF=YES REFRESH='EG GRA=(GRA);MAP H GRA=(GRA)' TIME=20:00 20:59 For reference, the time is now 21:30, so I am asking for all images for a previous hour for which there were 11. >I checked the McIDAS web user's guide on the ALL >keyword of IMGDISP. It says that IMGDISP would work even >if the total number of images in the section is less than >what's specified in ALL. Yes, and it did for me. It will and should fail, however, if there are no images in the TIME= range you specify. >I tried to use the REP keyword, >but it requires a position number, which I do not know if >I run the command in a script. You probably want to stay with the ALL= keyword. >The CYC and SEQ keywords did not seem to work either. They work for me, but I don't think that they give you the controls that you want. > Another question I have in mind is regarding the >point source surface data. Are sea-surface temperatures >decoded for ships and buoy data? Yes. The ship and buoy data that is decoded is made accessible in the RTPTSRC/SHIPBUOY dataset. >If yes, is there a >parameter name (e.g. SST) for plotting using SFCPLOT? The parameter for temperature will be T. Here is a simple example: SF 1 ERASE SFCPLOT T NACONF DAT=RTPTSRC/SHIPBUOY > Thanks again. No worries.
