Plotted data included winds, clouds, current and past weather etc., and so it resulted in much more than just a map of sea level pressure but it was a summary of all the weather, especially fronts, on a single map. infrared air conditionerSurface pressure is the atmospheric pressure at a location on Earth's surface (terrain and oceans). It is directly proportional to the mass of air over that location. For numerical reasons, atmospheric models such as general circulation models (GCMs) usually predict the nondimensional logarithm of surface pressure.
