  • grid = F160  - full (or regular) Gaussian grid with 160 latitude lines between the pole and equator
  • grid = N320  - ECMWF original reduced Gaussian grid with 320 latitude lines between the pole and equator, see Reduced Gaussian Grids for grid numbers used at ECMWF
  • grid = O640 - ECMWF octahedral (reduced) Gaussian grid with 640 latitude lines between the pole and equator
