Description
1 min averaged, multi-source, near-Earth solar wind magnetic
field, plasma and energetic proton flux data, plus AE, AU, AL, Kp, ap, and Dst
geomagnetic indices, Polar Cap (Thule) index, F10.7 index, and Rz (sunspot number).
The ram pressure is calculated using P=rho*Np*Vp², where rho=1.672622*(1+4*(1/(1-He++_ratio)-1)).
We use rho=2 here, which corresponds to a ratio of He++ between 4% and 5%.
