Lev changing in every time step

Dear all, Usually plots using "gsn_csm_contour" have a one dimension array with the levels, which are considered the same for every time step, as the following: ;---Generate some dummy data.   level = (/1000, 850, 700, 500, 400, 300, 250, 200, 150, 100/)   time = ispan(1,4,1)   ntim = dimsizes(time)   nlev = dimsizes(level)   data = generate_2d_array(10, 12, -20., 17., 0, (/ nlev,ntim/)) ;---Name the dimensions and attach coordinate arrays   data!0 = "lev"   data!1 = "time"   data&lev = level   data&time = time plot = gsn_csm_contour(wks,data,False) How can I do a plot taking into consideration variations in pressure for every time step? In this case I would need a two dimensional array with levels, as the following: level = (/(/1000, 850, 700, 500, 400, 300, 250, 200, 150, 100/),(/1050, 800, 709, 510, 430, 280, 270, 190, 150, 120/),(/1100, 830, 730, 510, 400, 300, 230, 200, 150, 103/),(/1030, 850, 700, 500, 480, 320, 250, 210, 150, 108/)/) data&lev = level  plot = gsn_csm_contour(wks,data,False) But this is currently not possible. Do you know how I would do it? Best wishes, Rodrigo.
