I need to calculate the fundamental atmospheric parameters, I mean the actual ones, this is not an exercise but a model for a real world application so I need to take account of the humidity of air. I need to calculate the density of the air, and I've solved this by implementing this calculator in MATLAB. But now I need to find a way to calculate the input parameters which are:
- Air Temperature
- Altimeter Settings (Which is the barometric pressure right?)
- Relative Humidity
given a certain altitude in meters above the sea level. If it's not possible to calculate all the three parameters, given an altitude, please show me a way to calculate the possible ones. For example I know that for the barometric pressure the best equation is the Laplace equation which is an improved version of the barometric formula right?
