ECMWF operational analysis (2)

Hi, This is an old thread but unfortunate all the link in the previous one doesn't work anymore. So i want to reconstruct wind field from spherical harmonics coefficients and would like to see some ncl working examples.  BTW maybe it will be easier to download post processed ECMWF operational analysis dataset on the regular 0.225x0.225 grid instead working with the original dataset?     u_g = a->U_GDS50_ISBL(k,:,:,:)  print(u_g) Variable: u_g Type: float Total Size: 5120000 bytes             1280000 values Number of Dimensions: 3 Dimensions and sizes:    [real_imaginary | 2] x [g50_lat_4 | 800] x [g50_lon_5 | 800] Coordinates: Number Of Attributes: 12   initial_time0_hours :    1817184   center :    European Center for Medium-Range Weather Forecasts (RSMC)   long_name :    U velocity   units :    m s**-1   _FillValue :    1e+20   level_indicator :    100   gds_grid_type :    50   parameter_table_version :    128   parameter_number :    131   level :    200   forecast_time :    0   forecast_time_units :    hours Thank you!! sk
