- Аннотация: In July 2016 high cadence data from the new DSCOVR satellite launched at the Lagrange point in February 2015 became available. On the basis of these data a binary (large-small) three-parameter classification of solar wind types according to the main hydrodynamic parameters (speed, density, temperature) is presented, and examples of the determination of different types of solar wind in real time are given. We get eight types of solar wind: hot-fast-dense, cold-fast-dense, hot-slow-dense, cold-slow-dense, hot-fast-rarefied, cold-fast-rarefied, hot-slow-rarefied, cold-slow-rarefied comparing to some average values for given time intervals. These types occur at different frequencies and are consequences of different solar activity sorts. The most interesting situations correspond to extreme values because of magnetospheric effects. This report considers possible solar `sources` of listed types depending from the averaging scale. `Sources` can be macroscopic or microscopic, dark or bright, dense or rarefied, etc. For their quantitative description the equations of MHD with dissipation or the plasma kinetics equations are used. In order to characterize and compare `sources` it is convenient to use dimensionless scaling analysis.
