Global maps of ALMA observation at two different pressure levels: 11 mbar (~ 74 km) and 0.01 mbar (~ 100 km). Colorbar shows the normalized percentage difference between selected pair of days: top: the first day and the second day of ALMA vertical temperature profiles; middle: the first and the third day; and bottom: the third and the fourth day of observation, as indicated in the figure. The absolute temperature uncertainties is 8%, as indicated in Table 3.
