Answer:
Meteorologists are interested in average temperatures
Physicists must be concerned with the distribution of incoming photons with respect to the energy that they carry - for instance, the ozone layer intercepts photons at particular energies - and there has been a hole in the ozone layer due to chemicals emitted by mankind - it seems that one would have to consider the effects of chemicals on the ozone layer (air conditioners, spray paints, industrial processes, etc.) to obtain a more accurate description of the processes involved
So it seems that different backgrounds will lead to different interpretations of the data
