AEFF high resolution WRF ARW gridded data

AEFF runs version 3.1 of the ARW twice daily. Selected output is available in either netcdf or grib format. The links in the table below direct users to root web directories for grib or netcdf data files. Please contact AEFF for more information on these files or to make a special data request.

The directory and file naming conventions are as follows:

For netcdf files : $jjj/mph/$cccc/jpl_wrfmph_d01_$yyyy-$mm-$dd_$hh:00:00.$jjj.$cc.gz

For data in grib 1 format: $yyyy$mm$dd/WRFPRS_d01.$HHH.$yyyy$mm$dd$cc.mph

$cc -> 2 digit forecast initialization 00 | 12
$dd -> 2 digit day of month (UTC) 01, 02 .. 31
$hh -> 2 digit hour of day (UTC) 00, 01 .. 24
