Thanks for providing your script and data.

To turn off the height label, set:

res@gsnPresHgtHeightLabelOn = False

The problem with your X tickmarks is that you also need to set this resource:

      res@tmXBMode = "Explicit"

On your X axis, you have non-monotonic values. The start at 6,5,4,...1, 0 and then jump to 23,22,21,20, and so on. I assume these are supposed to be hourly values

You should fix these values so they are based not just on hours, but days too. I can't tell what your dates are supposed to be, but here's one way you can "fix" them, by turning these hours into fractions, and adding a day countdown:

;---Rough estimate of the number of days.
  ndays = num(SO2&TIME.eq.0)

  ntim = dimsizes(SO2&TIME)
;---"Fix" SO2&TIME
  do i=0,ntim-1
    if(SO2&TIME(i).eq.23) then
      ndays = ndays-1
    end if
    SO2&TIME(i) = ndays + SO2&TIME(i)/24.
  end do

You would then need to set tmXBValues with:

   res@tmXBValues = SO2&TIME(5::10)

Although I think you might want to start at index 6 instead of 5?
