Re: wind gfs

Christelle,

To reference a specific value of a coordinate array, you need to place the
coordinate in curly braces. This tells it to look for the value of that
coordinate variable instead of the index of that coordinate variable. In
your case, the vertical coordinate of the XXXX_P0_L103_GLL0 variables are
(/10,80,100/) - so what you do right now is try and refer to the 11th index
of that 3-value array, which is clearly out of bounds. You'll want to
change your statements to look like:

UGRD_P0_L103_GLL0({10},:,:)
VGRD_P0_L103_GLL0({10},:,:)

To read more on the variable subscripting, see this section of the NCL
Language Guide:
