Total Solar Irradiance Trend and Tropospheric Dynamical Coupling
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 ...
متن کاملLong-term global temperature variations under total solar irradiance, cosmic rays, and volcanic activity
The effects of total solar irradiance (TSI) and volcanic activity on long-term global temperature variations during solar cycles 19-23 were studied. It was shown that a large proportion of climate variations can be explained by the mechanism of action of TSI and cosmic rays (CRs) on the state of the lower atmosphere and other meteorological parameters. The role of volcanic signals in the 11-yea...
متن کاملReconstructed 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...
متن کاملACRIM-gap and total solar irradiance revisited: Is there a secular trend between 1986 and 1996?
[1] A gap in the total solar irradiance (TSI) measurements between ACRIM-1 and ACRIM-2 led to the ongoing debate on the presence or not of a secular trend between the minima preceding cycles 22 (in 1986) and 23 (1996). It was recently proposed to use the SATIRE model of solar irradiance variations to bridge this gap. When doing this, it is important to use the appropriate SATIRE-based reconstru...
متن کاملEvidence for power-law distributions of total EUV/XUV solar irradiance that correlate with solar activity
The identification of flares in solar datasets implies using a thresholding process which excludes the majority of low-emission regions. In this paper we investigate a different measure of solar emission: the distribution of the total solar irradiance when integrated over the disk, obtained using extreme ultraviolet/soft X-ray observations from the SOHO CELIAS/SEM instrument. We show that durin...
