NetCDF file readable by McIdas-V

[jinlee]

Hi Bob,

I've modelled my NetCDF file on the one you've given me and now it looks like McIdas-V is able to read it as point data.

One thing that's still not working is Image Display (Gridded Fields). When I try "Gridded Fields" "Color-Shaded Plan View" I get following error message,

java.lang.ArrayIndexOutOfBoundsException: 1

I tried to do that same using my colleague's McIdas-V which is version 1.7 and it correctly finished analysis and display. I'm running McIdas-V 1.6. Should I upgrade my McIdas-V?

Hi Jin -

You can pick up a McIDAS-V 1.7beta1 installer at:
http://www.ssec.wisc.edu/mcidas/software/v/unstable/
The user and password are both: mcv

Note that there is no officially supported version 1.7 yet. This 1.7beta1 installer is automatically built every night with all of the previous day's programming changes. This means that it has not been fully tested and you may come across some bugs. The netCDF-Java version in McIDAS-V 1.6 is 4.6.5, and in 1.7beta1 it is 4.6.10, so perhaps an updated netCDF version in 1.7beta1 will help with displaying your data.

If you give the 1.7beta1 build a try and run into any problems, please let me know.

Thanks -
Bob

Hi Bob,

I'll try installing the 1.7beta version and test it.

Thank you very much for your help over a number of weeks. I now have a better understanding of the NetCDF format that McIdas-V will accept. Your help is much appreciated.



Regards,

Jin
