[ncl-talk] Using NCL to Average Over Grid Cells

[Smith, Stuart]

Hello,

 

I am using NCL to average simulated output variables over many grid cells,
and evaluate the results between hydrologic models (LIS-VIC and VIC). The
simulated outputs for both models should be the same. When I compare results
of individual grid cells the results are the same, as shown below. However,
when I average over the total number of grid cells  (703 grid cells),  the
results are different which was unexpected (also shown below). I believe
this is an error with my plotting script.

 

I wanted to ask for guidance on correcting the difference in calculation, as
I can't determine what is causing the differences. In the attached
compressed file are examples of the LIS-VIC and VIC NetCDF output files
along with the scripts used to calculate the average for each. I hope this
file is not too large. I think the information within it is important for
analyzing the differences. Thank you for your time. 

 

 

 

Regards,

 

-Stuart
