    ------------------------------------------------------
    ncInput must be a NC.object created by netCDF4 package
    Example on NC.object:
     import netCDF4 as nc
     NC.object = nc.Dataset('xxx/xx.nc')
    Leadtime_idx specifies the index of the Leadtime 
    for most the NMME members,leadtime index:
    [0,    1,    2,    3,   ...]
    [0.5M, 1.5M, 2.5M, 3.5M,...]
    ------------------------------------------------------
    The returned varData matrixa could be either monthly
    precipitation or precipitation rate
