Re [ncl-talk] Transform the lambert conformal to cylindrical equitidistant

Overview of issues:

[1] X2D = new ((/ntime,MLON,NLAT/), float,-999)
    and the dimension numbers/names/ordering are not correct.
    X2D!0 = "lat"
    X2D&lat = lat
    X2D!1 = "lon"
    X2D&lon = lon
    X2D_at_units = x_at_units
    
    correct:
    
    X2D = new ((/ntime,NLAT,MLON/), float,-999)
    X2D!0 = "time"
    X2D&time= time
    X2D!1 = "lat"
    X2D&lat = lat
    X2D!2 = "lon"
    X2D&lon = lon
    X2D_at_units = x_at_units
   
[2] Assignment of attributes and coordinate variables
    should only be done once.

[3] I will answer the rest offline.
