Sentence examples for solar background from inspiring English sources
In free space optical communication, the deep ultraviolet (UV) spectrum with wavelength 200 280 nm is regarded as an appealing choice to overcome solar background radiation and relax pointing and tracking [3].
Irradiance data from the UNIS aurora station in Longyearbyen (www.unis.no) show a clear diel variation in solar background Ed in January, with an average maximum amplitude of 0.08×10−4 μmolphotons m−2 s−1, which is less than half the minimum detection level for the human eye.
To guide the design, we have modeled the solar noise background and developed simple algorithms, based on post-detection Poisson filtering (PDPF), to optimally extract the weak altimeter signal from a high noise background during daytime operations.

An overview of the ongoing work performed at the NOAA Space Environment Center is presented with examples illustrating: (a) global.3-D interaction of a CME propagating in structured background solar wind, (b) incorporation of a more realistic ambient solar wind, (c) merging of coronal and heliospheric models to track CMEs, and (d) near-Earth solar wind simulations.
Fast CMEs are those that travel faster than the background solar wind (which has an average speed of about 400 km [240 miles] per second).
After that date, the RCP4.5 scenario was assumed, as well as a background solar irradiance level and a constant volcanic aerosol load.
Numerical results are discussed for a CME driven by local plasma density enhancement with a simplified representation of the background solar wind.
These disturbances are superimposed upon the background solar wind and, if directed towards earth, are the proximate causes of potentially disastrous geomagnetic storms 2-6 dafterfter leaving the sun.
From the distribution diagrams of CME, ICME and IP shock speeds, we note that a large number of events tends to narrow towards the ambient (i.e., background) solar wind speed (∼500 km/s) in agreement with the literature.
