Hi Robb:

I guess now I am really confused. It works on IDV2.0 but not IDV2.2b1.



Greg,
That's because in IDV2.0 there was a bug in the version of nj22 that skipped duplicate records in the grib file. The bug has been fixed. 
 For instance, here's 2 records from the grib index file.
1 0 -1 176 8 103 8229.0 255 0.0 2006-12-18T23:00:00Z 0 921322765 2164150 2206536 2 false
1 0 -1 176 8 103 8229.0 255 0.0 2006-12-18T23:00:00Z 0 921322765 3394504 3405226 2 false
fields 2-5 determine the parameter, so the parameters are the same. it also has the same level 103 8229.0 so the 2nd record is a duplicate of the first including the time. Thats the first problem. The second problem is the number of points from the GDS, Nx = 301 Ny = 225 should have 67725 points. The first record has 67725 but the second only has 17063 points. That caused major problems when you try to display the parameter. You need to point this out to the data provider. is this file a combination of 2 different files? the GDS Nx and Ny are wrong for the records that only have 17063 points. Why are there duplicate records in the file for all the parameters? Can you send the data provide the file and have them analysis the above problems. If the wrong duplicated were eliminated, the file could be read/displayed properly in the IDV. 

Robb...


As always any help is appreciated.

Greg ...

I'm running IDV 2.0 on XP and all three parameters display fine for me.   I do get a lot 
of "duplicate record" error messages in my system window.

I don't know a lot about this data, or the icing patterns on that date, so I 
could be missing something with the data that is obvious to you.

I've attached an image of LAT (or really Icing Probability).  What sort of 
problems are you seeing?

To display the grib files I am running IDV 2.2b1 on a windows XP Dell.

Hi, Greg -

What sort of problems are you seeing with this grib file?   For me, LAT and MLN 
work fine, but some of the SIPD grids do not work (e.g. LEV=1219 works fine, 
but LEV=9144 fails).  Is this what you're seeing?

Are you using McIDAS-X, or IDV, or ???  And what version are you running?   I 
ran my tests on McIDAS-X 2006B.  I have not tried the IDV.

Greg,



 x8 file that was submitted with your bug report has some major

problems.  the GDS has lat/lon of 301/225 so that means there

should be 67725 points for each parameter. just looking at parm

176 i found some of the data had 67725 points and others had

17063 points. i even checked the code on the debugger.  i made a

script to extract the number of points for each record that i'll

include the results. it's strange that the number of points start

out correctly but then revert to 17063.



Are you sure that this is good data??? Maybe you can report these

finding to the data provider for some explainations.



Robb...



length is number of pts.

jeff,



we have looked at this problem, at first we thought it  was a problem in

the grib library but the x8 file check out ok. there is something strange

Are you still looking at the problem?



Could you drop a line to Greg and tell him that you are still investigating

his problem. I'd rather not leave him hanging, especially since

he was the victim of a bunch of false positive spam filtering.
