[ncl-talk] FW: spatial interpolation so bad?

[xiaoming Hu]

Hello  Folks

I have some station observation. I want to do spatial interpolation to get spatial distribution. 
See the figure I got: 
http://www.caps.ou.edu/micronet/OKCmicronet/Spatial/200901/wrf_d05_OKCmicronet_UHII_hourly_smallerD_28.png
              
In the figure, the dots are the original observation.   Apparently the background spatial distribution is not good (not matching the original observation well).   How can I get better interpolated spatial distribution based on station observations? 
Here is my script:

Here is the data needed by the script:

Thanks a lot
