Reconstruction of Helio-latitudinal Structure of the Solar Wind Proton Speed and Density [PDF]
The modeling of the heliosphere requires continuous three-dimensional solar wind data. The in-situ out-of-ecliptic measurements are very rare, so that other methods of solar wind detection are needed.

Photosynthetic Active Radiation, Solar Irradiance and the CIE Standard Sky Classification
Plant growth is directly related to levels of photosynthetic photon flux density, Qp. The improvement of plant-growth models therefore requires accurate estimations of the Qp parameter that is often indirectly calculated on the basis of its relationship ...

The influence of solar wind variability on magnetospheric ULF wave power [PDF]
Magnetospheric ultra-low frequency (ULF) oscillations in the Pc 4–5 frequency range play an important role in the dynamics of Earth's radiation belts, both by enhancing the radial diffusion through incoherent interactions and through the coherent drift ...

Research on participation of flywheel energy storage in wind farm frequency regulation control
In view of a whole series of problems such as the reduction of system inertia, the increase of frequency fluctuation, and the deterioration of power quality caused by large-scale wind power integration, a flywheel with high power density is designed for ...

The Solar Wind as a Turbulence Laboratory [PDF]
In this review we will focus on a topic of fundamental importance for both astrophysics and plasma physics, namely the occurrence of large-amplitude low-frequency fluctuations of the fields that describe the plasma state. This subject will be treated within the context of the expanding solar wind and the most meaningful advances in this research field ...
