Even the NCEI server only has 3 hour forecast grids: https://www.ncei.noaa.gov/thredds/catalog/gfs-003-files/201803/20180301/catalog.html Cheers, Sean > Dear support, > > Great job with the Unidata server, it is very useful. > > We were wondering if there is another catalog with GFS forecast but 1 hour > resolution instead of 3 hours.
