Re: [idvdevelopers] Idv netcdf problem

Hi Don, Tom and others,

I am attaching another .nc file and its dump which can be opened using IDV
nightly build .Another hearder 5.txt is attached similar to out.txt,
generated from a big file which can not be opened using nightly build.


As far as I noticed that the only difference between these two header dump
is 5.nc has one more variable (z) which is absent at out.txt . Otherwise
almost same.

When I try to open this with netCDF file it says , no grided data is found.

If possible, please give suggestions.

Thanks

Maswood
