Saving Range when Displaying GOES IR Temp (band 4) Image

[Greg]

Good Afternoon:

Probably not understanding how to do this but every time I display an GOES IR Temp image I want the range to be 330 to 200. Now I have to change the range after the image is displayed. After changing the range I did left click on IR Image > File > Save > Save as Parameter Defaults > OK. Exited McV and restarted. Loaded a IR Temp Image but range did not change. Still 0 to 287.1.

Any help is appreciated.

Oh, by the way, I had no luck in getting the jython code for brightness to temp to work.

Thanks ..

Hi Greg,

What was the problem you were having with the jython code? Can you describe a bit more where you are having trouble? I used the file you sent to the help desk and was able to successfully get the formula to work.

Hi Jess:

Put method (below) in Local Jython User's library. Right clicked on brightnessToTemp > Insert IDV Action > General > Create Formula > this gets appended to the method ... idv.handleAction('action.edit.formula.create') > Save... get this .. There was an error in the Python library: Traceback (innermost last): (no code or object) at line 0 Syntax Error: ('invalid syntax', ('<string>','3,1, 'b=a[0];'))


def brightnessToTemp(a):
b = a[0];
m = mask(b,"<",176.)
b = m*(660.-b)/2. + (1.-m)*(418.-b)
return newUnit(b,"Temperature","K")

Hi Greg,

I took a look at my Jython library and I think I know what the problem is. Jython can be picky about indentations. Try indenting everything below the first line (I used two spaces) and save again. I removed my indentations and got the same error you listed below.

Hi Greg... Considering the saving range problem...

I guessing that it's not saved, because once you save a value in the Parameter defaults editor with your method, the "Parameter" by default is something like 78_Band4_TEMP (for a GOES-12 10.7 um image, satellite number, band number, unit). So, if you save that, only when you load another band 4 GOES-12 image would you see your change.

To make it more universal, you can change the Parameter name to ".*_TEMP" This should force any image display of TEMP values to use your saved range. If you are just considering GOES IR TEMP images of the 10.7 um variety, then I think "7.*_Band4_TEMP" should do it.

Note: For the wildcard, you need ".*" to mean "any text here" not just "*" I learned that in the help:

Let us know if you have problems with anything.
Thanks, Jay

Good Morning:

Well the brightnessToTemp formula is working. However, I am having no luck in saving data using the parameter defaults editor tool. I have tried all sorts of combinations for the parameter ("7.*_Band4_TEMP", ".*_TEMP", etc) but it does not save the values.

Any further help is appreciated.

Thanks ...

Hi Greg... I'm seeing the same problem you are in beta1. When I was doing my testing, I was using a test version of beta2 and it appears to work correctly with aliases there. We plan to make beta2 available in the near future, but there are a couple of bugs and further enhancements that need to be resolved before we release it.

Thanks, Jay
