>From: Unidata User Support >Organization: UCAR/Unidata >Keywords: 200106201031.f5KAVv116018 McIDAS ehancements Brian, Way back at the MUG meeting, we talked about me getting access to McIDAS versions of the enhancement tables discussed in: http://www.cira.colostate.edu/ramm/visit/istpds/awips/lookup.html Yesterday, I cut and pasted the "How to create this enhancement in AWIPS" from each of the types disucssed in links from the above page. I successfully created most of the enhancements, and they look like the displays shown (good thing). I did run into a couple of problems, so I am writing for help! First, a minor point. I see no difference in the enhancement listing for 'IR (channel 4) (9)' and 'IR (channel 5) (10)'. Am I seeing things incorrectly, or is this actually the case? Second, the enhancement I produce using the information for 'WV/IR' does not end up looking like the one used in the example display. In particular, the specification: Temperature (C) Red Grn Blu Red Grn Blu end of scale to -35.0 1 1 1 253 253 253 -35.0 to -38.0 255 235 80 216 196 80 -39.0 to -45.0 196 177 80 82 81 80 -46.0 to -52.0 103 81 80 210 81 80 -53.0 to -61.0 255 81 233 102 81 102 -62.0 to -69.0 80 100 102 80 255 255 -70.0 to -72.0 80 216 80 82 82 82 -79.0 to -86.0 125 125 125 255 255 255 -87.0 to -90.0 80 80 226 80 80 139 -91.0 to -109.0 81 81 81 199 199 199 would seem to display the gray scale portions of the WV/IR composite in gray shades varying from black to nearly pure white. The example image, however, does not show this range of gray scale values. My question is why not? Am I missing something here? (I am using the correct B to T conversion for GINI WV: T = 263 - 0.196 * B). Given this mismatch between the enhancement I create using the listed values and the displayed image, I am now uncertain abou the other color enhancements I created from the examples (although most look like the displays). Do you have enhancements in McIDAS .ET form for these that I could grab and compare to mine? Also, has CIRA coined "standard" .ET names for any/all of the enhancements referred to in the above web page? If so, I would like to adopt them so my users will not get thrown by name inconsistencies. FYI, I am intending to include all of the enhancements referenced in the web link above in my next McIDAS addendum, and I desperately want to get this out by tomorrow afternoon. Any sage advice you can provide and especially access to McIDAS .ET enhancements you can give me access to would be _greatly_ appreciated. Tom
