Sorting Issue

[Oliver ANGELIL]

Hi,

I am working with Station Data files in GrADS 1.8.

X , Y varying (horizontal X, Y plot)
Z = 1
T varying (360 days)

Each pixel displays a colour coded value for precipitation. I'm trying to sort precipitation from least to most, for each pixel, through the time series. This is because I want to display an image of the 90th percentile, to work out a vague probability of extreme weather at each pixel. 

How would I go about sorting in GrADS? I am relatively new to GrADS.

Oliver
