>> continue this code until you have a31 (for 31 days in December), then 'q define' will define your daily averages.  The numbers should be something like t=1,t=96 then t=97,t=193 and so on. (if 24hrs/day=1440min/day then 1440/15min increments=96 increments per day)

I tried changing the increment of my .ctl to once daily and creating a time series but I believe that is giving me the data for that specific time not a daily average.  Any help would be much appreciated (I'm fairly new to GrADS).
