[ncl-talk] Open a single level in GRIB2

[Miriam Teresita Llanes Monteagudo]

Hello
To open a file .grb2 I use the following command

f = AddFile ("2900.grb2", "r")

v = f-> VGRD_P0_L100_GLL0 ; [lv_ISBL0 | 26] x [lat_0 | 361] x [lon_0 | 720]

Thus it opens me to all vertical levels, longitudes and latitudes, but I
dont know how to open it only to a specific level, as well as the latitude
and longitude. I need to know how I open only the level of 50000 Pa, in a
given space

Thank you very much
