Solar zenith angle and frequency dependence of ionospheric D -region absorptionRadiowave absorptionsolar cycleIn this paper, the results of a series of extensive measurements of multifrequency radio wave absorption in the D -region of the ionosphere during the epoch of the minium period of the ...
Using observations from MAVEN's Neutral Gas and Ion Mass Spectrometer (NGIMS), we characterize the seasonal, solar zenith angle (SZA), and solar flux dependent variations of the O$^+$ peak and the O$^+$/O$_2^+$ ratio in the topside ionosphere of Mars. We find that the O$^+$ pea...
In this study, the effect of solar zenith angle () on enhanced vegetation index (EVI) of a Guyanese tropical rainforest was studied. For this sub-crown resolution, hyperspectral data have been collected with an unmanned aerial vehicle (UAV) at five different solar zenith angles in a 1-day...
Fig. 1 The ENA intensity observed by SARA on Chandrayaan-1 on 6 February 2009. Thecolouras well as the length of thelinesindicate the strength of ENA signal. It can be seen that the ENA intensity varies with the solar zenith angle. The weak signals on night-side is due to instrument ...
(1998) gives the standoff distance of the magnetopause (R(φ)) as a function of the solar zenith angle (φ) as $$R(\phi) = {R_0}{\left({{2 \over {1 + \cos \phi }}} \right)^\alpha },$$ (1) where the factors α and R0 depend on the IMF Bz and solar wind dynam...
The surface solar spectrum depends on the solar zenith angle (SZA), cloudiness, aerosol concentrations, the columns of atmospheric constituents (such as ozone and water vapor), ground reflectivity (albedo), the Sun–Earth-distance and the altitude. ...
2.1.1 Solar elevation angle The solar zenith angle θz is the angle measured directly from overhead to the geometric center of the Sun׳s disc. The solar elevation angle h is the altitude of the Sun; the angle between the horizon and the center of the Sun׳s disc. The relation betw...
