NCEP Downscaled GFS / Extended Eta (DGEX) Home Page

NCEP is making daily real-time parallel production runs of the Downscaled GFS / Extended Eta (DGEX). To run the DGEX, the 78-h operational NAM forecast is interpolated to smaller 12 km Eta domains, and a 78-h to 192-h forecast is made, using the previous 6-h old GFS forecast for lateral boundary conditions. Click here to see the computational domain of the DGEX runs over the CONUS and Alaska.

This is the current schedule:

0000Z, 1200Z : Alaska

0600Z, 1800Z : CONUS

Go to the DGEX log for the status of DGEX runs on the NCEP ftp server

These links will send you to a web page with the latest run for the specified DGEX domain:

CONUS; cycle = 2008090706

Alaska; cycle = 2008090700

DISCLAIMER : This web page is not "operational" and therefore not subject to 24-h monitoring by NCEP's Central Operations staff.
