Total solar irradiance satellite composites and their phenomenological effect on climate

نویسنده

چکیده

Herein I discuss and propose updated satellite composites of the total solar irradiance covering the period 1978-2008. The composites are compiled from measurements made with the three ACRIM experiments. Measurements from the NIMBUS7/ERB and the ERBS/ERBE satellite experiments are used to fill the gap from June 1989 to October 1991 between ACRIM1 and ACRIM2 experiments. The climate implications of the alternative satellite composites are discussed by using a phenomenological climate model for reconstructing the total solar irradiance signature on climate during the last four centuries.

Phenomenological solar contribution to the 1900–2000 global surface warming

[1] We study the role of solar forcing on global surface temperature during four periods of the industrial era (1900– 2000, 1900–1950, 1950–2000 and 1980–2000) by using a sun-climate coupling model based on four scale-dependent empirical climate sensitive parameters to solar variations. We use two alternative total solar irradiance satellite composites, ACRIM and PMOD, and a total solar irradia...

Phenomenological reconstructions of the solar signature in the Northern Hemisphere surface temperature records since 1600

[1] A phenomenological thermodynamic model is adopted to estimate the relative contribution of the solar-induced versus anthropogenic-added climate forcing during the industrial era. We compare different preindustrial temperature and solar data reconstruction scenarios since 1610. We argue that a realistic climate scenario is the one described by a large preindustrial secular variability (as th...

Empirical analysis of the solar contribution to global mean air surface temperature change

The solar contribution to global mean air surface temperature change is analyzed by using an empirical bi-scale climate model characterized by both fast and slow characteristic time responses to solar forcing: t1 1⁄4 0:470:1yr and t2 1⁄4 872yr or t2 1⁄4 1273yr. Since 1980 the solar contribution to climate change is uncertain because of the severe uncertainty of the total solar irradiance satell...

ACRIM total solar irradiance satellite composite validation versus TSI proxy models

The satellite total solar irradiance (TSI) database provides a valuable record for investigating models of solar variation used to interpret climate changes. The 35year ACRIM total solar irradiance (TSI) satellite composite time series has been revised using algorithm updates based on 13 years of accumulated mission experience and corrections to ACRIMSAT/ACRIM3 results for scattering and diffra...

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...
