Total Solar Irradiance Trend and Tropospheric Dynamical Coupling
نویسندگان
چکیده
The irradiance of the Sun changes slightly with the solar cycles. In this paper the variation of heliospheric current sheet tilt angle with the total solar irradiance is examined. The average value of the tilt angle, following both the radial and the classic models are considered at length with a view to re-look some interesting features. Intensity of protons and antiprotons in different solar polarities are compared and the variations of 27-day average cosmic ray intensity are counted for investigating the influences of the Sun on terrestrial atmosphere.

Reconstructed and measured total solar irradiance : Is there a secular trend between 1978 and 2003 ?
Total solar irradiance reconstructed between 1978 and 2003 using solar surface magnetic field distributions is compared with three composites of total solar irradiance measurements. A good correspondence is found with the total solar irradiance composite from PMOD/WRC, with no bias between the three cycles. The agreement with the other composites (the ACRIM composite, mainly based on the Active...

Abstract: Clean air is a necessity for human well-being and health. Air pollution is a major threat to humans and other organisms and is considered as one of the environmental challenges. Today, with the increase in air pollution, the need to know more about the causes of its occurrence has been raised. The various consequences of air pollution have made air quality monitoring and control inev...

Herein we adopt a multiscale dynamical spectral analysis technique to compare and study the dynamical evolution of the harmonic components of the overlapping ACRIMSAT/ACRIM3 (Active Cavity Radiometer Irradiance Monitor Satellite/Active Cavity Radiometer Irradiance Monitor 3), SOHO/VIRGO (Solar and Heliopheric Observatory/Variability of solar Irradiance and Gravity Oscillations), and SORCE/TIM (...
متن کاملThe Sun ’ s Total Irradiance : Cycles , Trends and Related Climate Change Uncertainties since 1976
A composite record of the Sun’s total irradiance compiled from measurements made by five independent space-based radiometers since 1978 exhibits a prominent 11year cycle with similar levels during 1986 and 1996, the two most recent minimum epochs of solar activity. This finding contradicts recent assertions of a 0.04% irradiance increase from the 1986 to 1996 solar minima and suggests that sola...
متن کاملA New Look at Solar Irradiance Variation
We compare total solar irradiance (TSI) and ultraviolet (Fuv) irradiance variation reconstructed using Ca K facular areas since 1915, with previous values based on less direct proxies. Our annual means for 1925 – 1945 reach values 30 – 50 % higher than those presently used in IPCC climate studies. A high facula/sunspot area ratio in spot cycles 16 and 17 seems to be responsible. New evidence fr...
