- gsolve.reductions.anomalies.compute_free_air_anomaly(absolute_gravity, normal_gravity, free_air_correction)[source]#
Calculate the free air anomaly.
The free air anomaly is calculated using the formula:
\[FAA = AG - (NG + FAC)\]- Where:
FAA = Free Air Anomaly
AG = Absolute Gravity
NG = Normal Gravity on the ellipsoid surface
FAC = Free Air Correction
- Parameters:
- absolute_gravityArrayLike
Absolute gravity in mGal, typically from the gsolve network adjustment.
- normal_gravityArrayLike
Gravity at the ellipsoid surface in mGal.
- free_air_correctionArrayLike
Free Air Correction in mGal at the station elevation.
- Returns:
- free_air_anomalyndarray
The free air anomaly in mGal.
