Robb, Thank for the quick response. I have made the modifications you suggested, ie setting La1/Lo1 to the south west corner of the full ETA218 grid and setting the grid_number to the list of all the tiles (there are 54, see map at http://www.emc.ncep.noaa.gov/mmb/research/tiles.218.html). I ran into a new problem: it seems that the GRIB file carries the "255" code for all the tiles and I got the following error messages: Dec 21 15:54:04 gribtonc.exe[28513]: 374 grid 255 not in grid_number list in eta.t00z.awip21806.nc
francois, sometimes in stitched together grid files the grid numbers are not used, only 255 is used. so replace with grid_number = 255;
I have attached my CDL file for your information and put two tiled files (tile 23 and tile 32) at: ftp://ftp.rap.ucar.edu:incoming/irap/vandenb/eta.t00z.awip21806.23 ftp://ftp.rap.ucar.edu:incoming/irap/vandenb/eta.t00z.awip21806.32
i get connection timed out errors on retrieval or chdir errors GET ftp://ftp.rap.ucar.edu:incoming/irap/vandenb/eta.t00z.awip21806.23 > eta.t00z.awip21806.23 <HTML> <HEAD><TITLE>An Error Occurred</TITLE></HEAD> <BODY> <H1>An Error Occurred</h1> 404 Can't chdir to irap </BODY> </HTML>
Other files can be found under the naming eta.tAAz.awip218FF.TT (where AA is the analysis time, FF the forecast lead time and TT the tile number) at: ftp://ftpprd.ncep.noaa.gov/pub/data/nccf/com/eta/prod/eta.20041221/
i get: Can't build data connection: Connection timed out i'm working at home and my connection doesn't permit tranfering of large data files. if the above solution doesn't work, i look at it tomorrow. robb...
