atmospheric_fieldSchmidthFieldFromIGRF

Workspace.atmospheric_fieldSchmidthFieldFromIGRF(self, atmospheric_field: pyarts3.arts.AtmField | None = None, time: pyarts3.arts.Time | None = None) → None

For forward calculations, this should be similar to atmospheric_fieldIGRF().

What it does different is that it is 1) not a direct computations matching the IGRF field, instead averaging the Legendre coefficient matrices.

What it does very different is that it supports retrievals of the magnetic field Legendre coefficients.
