[ncl-talk] interpolation warning

[Sunmin Park]

Dear NCL Users.

I try to interpolate 201 pressure to 17 pressure levels and use “int2p_Wrap”. 
It does interpolation but I get warning 
"warning:int2p: 1025 input array(s) contained all missing data. No interpolation performed on these arrays” 
with

  average_op_ncl :	dim_avg over dimension(s): year

I calculated the average of Extinction coefficient from CALIPSO for each month over the 7 years data (has 201 levels). And this averaged values should be interpolated by 17 levels. It seems that the interpolation worked but the Min. and Max values show wrong. How I can fix this? I appreciate any comments and suggestions.

Thanks in advance,
