I wish to overlay vector (u_plane, v_plane) over magnitude(spd i.e wind
speed). so tried it another way as per your suggestion like
u_plane!0 = "lat";
u_plane!1 = "lon"
u_new&lat= lat
u_new&lon= lon
v_plane!0 = "lat";
v_plane!1 = "lon"
v_new&lat= lat
v_new&lon= lon
spd_plane!0 = "lat";
spd_plane!1 = "lon"
spd_new&lat= lat
spd_new&lon= lon
still facing same issue
