[ncl-talk] questions about int2p_Wrap

[sunmin park]

Dear NCL users

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

Variable: levNew
Type: float
Total Size: 416160 bytes
            104040 values
Number of Dimensions: 3
Dimensions and sizes: [lat | 85] x [lon | 72] x [ALT | 17]
Coordinates:
            lat: [-85..85]
            lon: [-180..180]
            ALT: [1000..10]
Number Of Attributes: 2
  _FillValue : -9999
  average_op_ncl : dim_avg over dimension(s): year
(0) interpolated_01:  min=-9999     max=-9999

I used extinction coefficient from CALIPSO L3 and tried to get the average
of extinction coefficient for each month over the 7 years data. Then I got
the average value (ex: January(2007-2010) min=0   max=5.85379). But after
interpolation the values change and it (-9999) is missing value in the
files (I used @_FillValue= -9999).

Does anyone know why I am getting this warning and how I can solve this
problem?

Thanks in advance,
Sun-
