This sensor provides absolute pressure, required at all of ISFS's surface stations.  However, with the ability to resolve fractions of microbars, this sensor can also be used to measure turbulent or wave-driven pressure fluctuations or microbaroms.  Small-scale pressure gradients also can be measured, though likely will require offset adjustment since the absolute calibration is not as accurate as the resolution.  A limiting factor in gradient measurements often is the absolute height of the transducer.

Ambient Static Pressure

"Static pressure," also called "ambient pressure," is the pressure of the atmosphere at the flight level of the aircraft. It is called static pressure to distinguish it from dynamic pressure, which is the difference between the pressure present at a forward-pointing aperture like a pitot tube on the aircraft and the ambient pressure.
