I've just started playing KSP (today) and wondered if there is an Atmospheric model incorporated into the simulation with the usual air density, pressure and temperature changes, even a simplified one like the International Standard Atmosphere (ISA) model. I was also wondering if the science equipment will eventually actually measure something rather just a simple acknowledgement a measurment has been taken. I've not tried a the aircraft section particularly since the aerodynamics is undeveloped but its an area I hope will be improved. I know there supposed to aerodynamics modelling improvement in the beta update is there any news what type of model that will be?
