Does anyone know where I can find real (not approximate) solar wind data in LEO? I am particularly interested in the density and current of electrons

I found an answer in International Reference Ionosphere - IRI (2016) with IGRF-13 coefficients.

This page enables the computation and plotting of IRI parameters: electron and ion (O+, H+, He+, O2+, NO+) densities, total electron content, electron, ion and neutral (CIRA-86) temperatures, equatorial vertical ion drift and others.

It provides the electron density, temperature etc. of Earth's ionosphere from 100 to 2000km

While the Earth's magnetic field (see magnetosphere is sufficient to stop the solar wind proper (see Magnetopause there is still a plasma trapped in Earth's magnetic field lines which originates at least partially from the solar wind.
