Response to Question 1
The height in meters above Sea Level at the Point of observation is 960 meters MSL equivalent pressure MSL equivalent pressure also abbreviated as pMSL pMSL = pobs + pgzobs It is important to acknowledge that p is the density of air at the point of observation and g is the acceleration due to gravitational force and z is the height at the point of observation. In this case, p (density of air at the point of observation) = 1.2041 kg/m3; while g (acceleration due to gravity) = 9.81m/s2. The height in meters (z) at the observation point is 196 meters.
Taking these figures into consideration, pMSL will be attained as indicated below;
pMSL = 1.2041 + ( ...
