1 - The GrADS script Clima_Mth_GM_CFS12.gs do the Monthly 
    Global Mean of the fields zonal wind, meridional wind,
    temperature, specific humidity and geopotential height
    for the cases CFSR1, CFSR2 and CSF12 (weighted average
    between CFSR1 and CFSV2).

2 - The GrADS script Clima_Mth_GM_ERA_5.gs do the Monthly 
    Global Mean of the fields zonal wind, meridional wind,
    temperature, specific humidity and geopotential height
    for the case ERA_5.

3 - The GrADS script Plot_GM.gs plot the Monthly Global Mean
    of the fields zonal wind, meridional wind, temperature,
    specific humidity and geopotential height. 

4 - These Monthly Global Mean are considered to the year
    2024 at the GrADS control file.

Obs: These Monthly Global Mean are used to do vertical 
     extrapolation by the Get_Ener_UVZ procedures mainly
     at upper levels. These Monthly Global Mean are
     linearly interpolated in time for the day time of
     the data.
