Re: Fwd: Re: [netCDFJava #XIR-445342]: Problem with netCDF-Java CoordinateAxis returning wrong values

Hi Tom:

AFAICT, the new code is doing the right thing, namely removing the discontinuity at the longitude seam.. looking at the 2D longitudes, here are a few sample rows that seem correct. Following that is a row where the data has a discontinuity at it, not sure if that is causing problems in the IDV. Im seeing 3 such rows out of 13559.

Hi John,

It looks like you were the one that actually fixed the last error. Would
you mind taking a look at this one too?

Thanks!

Hi Sean...

Thanks again...but...  While the fix took care of _that_ file, the
same user has another file that is a little different which exhibits
the same issue!  Although the longitudes in the file are "valid" (and
in this case, it looks like most if not all are negative), the range
that shows up when the file is read by the IDV is -354.66013 to
25.322577!

I hope you all have time to look into this one, too!  The file is at:

<ftp://ftp.ssec.wisc.edu/pub/ssec/tomw/NSS.GHRR.NN.D08275.S0459.E0652_NASA_LaRC_cloud_properties_CERESmap.nc>

Thanks!

Hi Tom,

This will be in the nightly build tonight.

Cheers!

Hi John...

Thanks for writing back so fast!

Looks like it might be getting confused by the -999 missing values.
It appears to be swath data, but do you know why so many missing values ?


The scientist (at NASA Langley) says they always process their data in
1000 "line" chunks and only populate the regions they are interested
in...this also helps eliminate issues with overlaps.  We've had other
files from him before, but this one was the first that popped up with
this issue.  I figured since it worked in the old IDV version, it
might be a netCDF "issue".

Anyway, I have a fix for it. It will be in 4.3.18. 

Thanks!!!

Yuan/Julien/Sean -- when this gets into the IDV nightly, will you
please let me know?

Thank you.
