Plasmapause location

The lpp provides functionalities for calculating the plasmapause location.

Models:

• Carpenter and Anderson (1992)

Functions

rbamlib.models.lpp.CA1992(time, kp)

Calculates plasmapause location Lpp following Carpenter and Anderson (1992) [1]_, eq (7).

Parameters:

• time (ndarray) – Time in days as a numpy array.

• kp (ndarray) – Kp-index, vector of geomagnetic activity indices corresponding to the times.

Returns:

lpp – Plasmapause location Lpp as a vector.

Return type:

ndarray

Notes

The plasmapause location Lpp is calculated using the formula:

\[L_{pp} = 5.6 - 0.46 \cdot Kp_{24}\]

where (Kp_{24}) is the maximum Kp-index value in the last 24 hours.
