May be I haven’t used it enough. I use CDO to perform this operation and then use grads to visualize. This looks like you are interested in percentile of a given time span. Use CDO’s “timpctl” command. You can either get it done in 3 lines or a 1 line piped command. </p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:12.0pt'><b><span style='font-size:9.0pt;font-family:"Helvetica",sans-serif;color:black'>Bamidele J.
