CDO

Hello,

Consider the following grib2 file from the CFSR reanalysis:
https://nomads.ncdc.noaa.gov/data/cfsr/200508/wnd10m.gdas.200508.grb2

The output for ncdump and Java NetCDF is below with variable names
u-component_of_wind_height_above_ground
v-component_of_wind_height_above_ground

However,
CDO reports varible names are
10u
10v

The question is:
why CDO names variable like this?
is it possible to make CDO use the following names
u-component_of_wind_height_above_ground
v-component_of_wind_height_above_ground
?
