By netCDF rule, the type of _FillValue must match the the type of the variable with which it is associated.


You have:
   FSDSatt           =    True                  <==type logical  
   FSDSatt at _FillValue=9.999E20      <== type float


Hence, 'type mismatch'.


The solution, use


    FSDSatt  = 1.0   <== type float

hi,
  when i create a nc file with ncl , and assign _FillValue in it, part of code shows the following:
+++++++++++++++++++++++++++++++++++++++++++++  
  filevardef(fout01,"FSDS","float",(/"time","lat","lon"/))
      FSDSatt           =    True
      FSDSatt at mode      =    "time-dependent"
      FSDSatt at units     =    "W/m2"
      FSDSatt at long_name =    "incident solar (FSDS)"
      FSDSatt at _FillValue=9.999E20
      filevarattdef(fout01,"FSDS",FSDSatt)
   ++++++++++++++++++++++++++++++++++++++++++++


but the error information from the operation shows the below:
ncendef: ncid 131072: NetCDF: Not a valid data type or _FillValue type mismatch


i want to know how to assign _FillValue in nc file in ncl script?


thanks
