I don't have an enhancement that would produce the same display. I know that the folks at CIRA (Colorado State University) has a number of enhancements that were developed for RAMSDIS. I think that the RAP coloration of IR images are based on this (perhaps indirectly through use of a GEMPAK enhancement which would have been adopted because of the color scheme's use in RAMSDIS). It might be a good idea to send an inquiry to the mcidas-x email list (address@hidden) to see if any of the sites out there have enhancements that they are willing to share with the community. Since folks at SSEC are also on the mcidas-x email list, they might chime in with info as well. >I tried to run mcrun.sh, to test running McIDAS batch script, and I always >get: >stty: : Inappropriate I/O control operation >and no McIDAS commands can work (I tried to put some commands, like imgdisp.k >by example). I only modified MCHOME to be set to the proper >path. Nothing else has been changed... Hmm... I will have to take a look into this. I just took the copy of mcrun.sh and copied it to a working version in my McIDAS working directory and put in a simple imglist.k invocation to a dataset for which I have a DATALOCation, and it worked fine: cd $MCDATA mcenv << EOF # put McIDAS-X commands you want to run here, one command per line. # Example (note that these lines are commented out!!): # # dataloc.k ADD RTGINI adde.unidata.ucar.edu # imgdisp.k RTGINI/GE1KVIS STA=KMIA EU=IMAGE SF=YES REFRESH='EG;MAP H' # frmsave.k 1 miamivis.gif imglist.k RTIMAGES/GE-IR %cat mcrun.log Image file directory listing for:RTIMAGES/GE-IR Pos Satellite/ Date Time Center Band(s) sensor Lat Lon --- ------------- ------------ -------- ---- ---- ------------ 9 G-8 IMG 20 JUN 01171 16:15:00 23 71 4 imglist.k: done So, at least on the machine I am working on (RedHat 7.1 Linux), I can't reproduce your problem. One quick thought... Is LD_LIBRARY_PATH defined in the Unix session from which you are running mcrun.sh? If not, the following line from mcrun.sh might fail: LD_LIBRARY_PATH=$MCHOME/lib:$LD_LIBRARY_PATH >From address@hidden Wed Jun 20 07:22:03 2001 >Subject: McIDAS: IR stretch table in Celcius? >Hi again... >Is there a stretch table available in McIDAS with Celcius units instead of >Kelvin? No, and since the temperatures in satellite images in McIDAS are always in K, this is not easily done. If your objective is to be able to display a data BAR that has units in C, but you can make one yourself. First, take a look at the stretch table for GOES IR imagery, IRTEMP.ST: SU TABLE IRTEMP BREAKPOINTS STORED IN TABLE : IRTEMP.ST INPUT OUTPUT ----- ------ 163 255 241.9999 177 242 176 330 0 CALIBRATION TYPE : GVAR CALIBRATION UNITS : TEMP BAND NUMBER : -1 INTERPOLATION TYPE: LIN SU: DONE You can create the same stretch table, but in Celsius, as follows: SU INI IRTEMPC X TEMP SU MAKE IRTEMPC -110.16 -31.16 255 177 SU MAKE IRTEMPC -31.15 56.84 176 0 SU TABLE IRTEMPC BREAKPOINTS STORED IN TABLE : IRTEMPC.ST INPUT OUTPUT ----- ------ -110.16 255 -31.16 177 -31.15 176 56.84 0 CALIBRATION TYPE : CALIBRATION UNITS : TEMP BAND NUMBER : -1 INTERPOLATION TYPE: LIN SU: DONE Now, you can _not_ load the image using this stretch (because the values will still be interpreted as K), but you can use the stretch with BAR for labeling: IMGDISP RTIMAGES/GE-IR STA=CYQB EU=IMAGE REFRESH='EG;MAP H;BAR SU=IRTEMPC' The only thing wrong with this display is that the units listed by BAR for TEMP will still be [K]. A slight change/enhancement to bar.pgm could allow the user to specify his/her own unit for display (as a 4 or fewer character string). >Thanks a lot again for your support, You are welcome.

Christian- There are a couple of good sources for information on satellite enhancement tables. for McIDAS .ET files, see the NESDIS ORA FPDT page at http://orbit-net.nesdis.noaa.gov/arad/fpdt/enh/enh.html there's also a page at http://www.cira.colostate.edu/ramm/visit/istpds/awips/lookup.html which shows even more enhancement tables that was done for AWIPS. Each curve has the necessary info so that they can be re-created in McIDAS. It's also a more complete list of all of the curves from the GOES Users Guide. There's also some subtle differences from imagery that you might get from your own GVAR groundstation versus the NOAAport feed. There are a number of references at http://www.cira.colostate.edu/ramm/visit/istpds/awips/page1.asp As if that weren't enough, you can see some additional ideas for color tables at http://www.cira.colostate.edu/RAMM/rmsdsol/main.html The weather channel (USA) has in the last few months started using the water vapor color table from this site. http://cimss.ssec.wisc.edu/goes/dpiet/dpietmain.html Winter Storms http://cimss.ssec.wisc.edu/goes/misc/visit/enhancement.html Hope this helps.
