McIDAS-V Support Forums

Even if you set the valid range to 0-254 (since 255 is the missing value), or the non-converted byte value range, the surface temperature (or any of the scaled data) still comes out as the image I sent. Byte values, as you know, go from 0-255, so if it was scaling to missing for the majority of the ...

Color Shaded Plan View, which is what we've been using to display the gridded data from the AIT

In viewing sounding data from the AIT framework, I get a really wierd looking image for CAPE (CAPESoundings.gif) , with a bunch of hexagons where the clouds. However, using the UCAR netCDF tool box, I get a much better looking image (Mc-V_issue_soundings.jpg). Any idea why this is happening with bet...

I have a CF compliant (thanks to Tom W) netCDF file (attached). However, for scaled data, McIDAS-V (beta4) seems to have an issue displaying the unscaled data. In the image below, I have the result from the netCDF file from IDL, UCAR's netCDF tools user interface and McIDAS-V. As can be seen, both I...

Rick,

Yeah. Typically, the RGB's we do from SEVIRI and AVHRR are the VIS, 3.9 and reverse 11 micron BT for the RGB, respectively.

Rick,

How do you do the reverse of the IR channel??

Rick,

Got the first section done, but I was wondering if there was a way to do basically:

imgoper.k LD/TEMP.3 LD/TEMP.2 LD/TEMP.1 LD/COPY.1 FORM=CMAX ZERO=DATA SIZE=1632 2304

in -V (it is the same way, I think, as what you are saying)

Ok, I have several AVHRR overpasses that I have remapped and I want to combine them into one image, but I only want to 1). have the most recent data on top and 2). if the most recent data has a 0 and the previous image has an actual value, use that data. The issue everything is on the same grid. I r...

Thanks, I'll try that. Figured it might be a useful thing to have, since AK is part of the PG effort.

Seems a bit odd that the remapped files work, but the original files don't (though they seem to be fine in -X). Or is it the same issue in the non-remapped and the remapped files??
