Inquiry: Hi,

I am trying to use gribtonc to convert and tile the ETA 218 tiled
products available from:

ftpprd.ncep.noaa.gov:/pub/data/nccf/com/eta/prod/

Francois,

i went to the site, there were no files available.

I have attached my CDL file. The program works fine with one tile, but
when I try to use it with several tiles, then I got the following error
message:

Dec 20 18:29:49 gribtonc.exe[29974]: 1, eta.t00z.awip21806.nc nav.
mismatch La1: 33.011 != 19.9433

I didn't receive the cdl but here' a few comments. the La1 and Lo1 should
be the south west corner of the full ETA218 domain, sound like you coded
ti correctly. the grib_number should be all the grid tiles, for ecmwf it
is: grid_number = 1,2,3,4,5,6,7,8,9,10,11,12 ;

Here 33.011 is the latitude of the south west corner of the tile, while
19.9433 is the south west corner of the full ETA218 domain. One tile
having the dimensions 69x72 while the full domain have the dimensions
491x303.

I was able to tile other products such as ECMWF tiled data which were
not on a projection map. So I was wondering if the projection is the
problem.

all files should have the same projection

robb...

Thanks in advance for any help,

Francois
