<p class="MsoNormal"><span lang="EN-CA" style="font-size:10.0pt;font-family:"Verdana","sans-serif"">I am trying to calculate SPEI using the SPEI function in NCL with gridded data, but when I run the script, I get an error message saying that the subscripts
must be one dimensional. This is expected for data for one location, but not for gridded data. My sample script is attached (it’s basically the same as the example provided with the function).
