The Scaled Impulse at Altitude 'z' computes impulse using the ambient pressure, ambient temperature, pressure at the 'z' altitude and temperature at the 'z' altitude. This equation is part of Sachs scaling law.

About Sachs Scaling Law

In the case of blast waves from explosions produced at altitude, where ambient conditions can be very different from those at sea level, the most commonly used scaling law is that due to Sachs. The application of the Sachs scaling law leads to the formulation of altitude scaling factors.
