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.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>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.
