[ncl-talk] nan in data radar set, how to handle

[Geeta Geeta]

Hi Rick. 
Thanks for your suggestion. 
The "isnan_ieee" didnt work. but I converted the double to float and then it worked. 

refl    = doubletofloat(ref)
  reflec  = where(refl.eq."nan",-9999.,refl)
             asciiwrite("reflec.txt",reflec)
;            printVarSummary(reflec)
This is what I did.  But I still have one question. when the dataset is of the type "double", then how will "nan" be represented??? Can You pls explain???

The Figure is attached. 
Geeta.
