I think at the bottom-right the "GFS 22km" must be "GFS 13 km" for forecast days 0~10.
Will fix it. I think NOAA give us 0.25x0.25 degree resolution grid.
Maybe you 're right. http://www.nco.ncep.noaa.gov/pmb/products/gfs/#GFS
In this case 0.25 deg=15 NM = 28 KM.
I said 13 km resolution,
based on wikipedia https://en.wikipedia.org/wiki/Global_Forecast_System
Yep, they calculate 13km grid but they distribute 0.25x0.25 degree grid only
