       wks    = gsn_open_wks(...)

               ,"Orange","HotPink","Red","Violet", "Purple", "Brown", "Black"/)
       gsn_define_colormap(wks, colors)               ; generate new color map


       res at cnLevelSelectionMode = "ExplicitLevels"
       res at cnLevels             = (/0.1,1,5,10,20,30,50,75,100,150/) ; "mm/day"
