Synoptic radio observations as proxies for upper atmosphere modelling
The specification of the upper atmosphere strongly relies on solar proxies that can properly reproduce the solar energetic input in the UV. Whilst the microwave flux at 10.7 cm (also called F10.7 index) has been routinely used as a solar proxy, we show that the radio flux at other wavelengths provides valuable complementary information that enhances their value for upper atmospheric modelling. ...
متن کاملInfrared Scattering Observations in the Upper Atmosphere
Observations of sky emission and absorption in the far infrared (mean wavelength 120 /•) and, simultaneously, sky emission at wavelength 6 • have been made by P. Kuhn (ESSA): from the NASA CV-990 aircraft flying at 12-km altitude over the middle Pacific at latitudes 10ø-15øN. A lack of correlation between the nearand far-infrared data, especially during times of visible cirrus cloud cover above...
متن کاملThe Mg II index for upper atmosphere modelling
The solar radio flux at 10.7 cm has been used in upper atmosphere density modelling because of its correlation with EUV radiation and its long and complete observational record. A proxy, the Mg II index, for the solar chromospheric activity has been derived by Heath and Schlesinger (1986) from Nimbus-7 data. This index allows one to describe the changes occurring in solar-activity in the UV Sun...
متن کاملStudy of the Martian Upper Atmosphere using Radio Tracking Data
Since the first in situ observations of the Martian atmosphere were made by the twin Viking landers, we have learned considerably more about its composition, dynamics and variability. Not only did the new data on global atmospheric densities generate opportunities to understand the atmospheric composition of early Mars and supply constraints at the upper limit of General Circulation Models, it ...
متن کاملRadio Versus EUV/X{Ray Observations of the Solar Atmosphere
This paper 1 reviews the contrasting properties of radio and EUV/X{ray observations for the study of the solar atmosphere. The emphasis is placed on explaining the nature of radio observations to an EUV/X{ray audience. Radio emission is produced by mechanisms which are well-understood within classical physics. Bremsstrahlung tends to be dominant at low frequencies, while gyroresonance emission ...
