An assessment of the solar irradiance record for climate studies

open access: yesJournal of Space Weather and Space Climate, 2014
Total solar irradiance, the spatially and spectrally integrated radiant output from the Sun at a mean Sun-Earth distance of 1 astronomical unit, provides nearly all the energy driving the Earth’s climate system.

Total Solar Irradiance and Stroke Mortality by Neural Networks Modelling

open access: yesAtmosphere, 2023
The purpose of this study was to examine the potential effect of solar energy on vascular stroke mortality in a Greek region by using neural networks analysis. The time period studied was from 1985 to 1989.

The Maunder minimum and the Little Ice Age: an update from recent reconstructions and climate simulations

open access: yesJournal of Space Weather and Space Climate, 2017
The Maunder minimum (MM) was a period of extremely low solar activity from approximately AD 1650 to 1715. In the solar physics literature, the MM is sometimes associated with a period of cooler global temperatures, referred to as the Little Ice Age (LIA),

Variability and trends in surface solar spectral ultraviolet irradiance in Italy: on the influence of geopotential height and lower-stratospheric ozone [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
The short- and long-term variability of the surface spectral solar ultraviolet (UV) irradiance is investigated across Italy using high-quality ground-based measurements from three locations: Aosta (45.7∘ N, 7.4∘ E, 570 m a.s.l.), Rome (41.9∘ N, 12.5∘ E ...

Determination of time-dependent uncertainty of the total solar irradiance records from 1978 to present

open access: yesJournal of Space Weather and Space Climate, 2016
Aims. The existing records of total solar irradiance (TSI) since 1978 differ not only in absolute values, but also show different trends. For the study of TSI variability these records need to be combined and three composites have been devised; however ...

INTRODUCTION OF CLOUDS IN DART MODEL [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
Clouds cover around two thirds of the Earth’s surface. Most of them are thick enough to influence the radiative budget of our planet: they increase the top of atmosphere (TOA) exitance and they alter the bottom of atmosphere (BOA) direct and diffuse ...

Solar Irradiance Variability: Comparisons of Models and Measurements

open access: yesEarth and Space Science, 2019
The Earth system responds to solar variability on a wide range of timescales. Knowledge of total solar irradiance (TSI) and solar spectral irradiance (SSI) spanning minutes to centuries is needed by scientists studying a broad array of research ...

Understanding the secular variability of solar irradiance: the potential of Ca II K observations

open access: yesJournal of Space Weather and Space Climate
With the increasing concern about climate change, it is important to have accurate information on the individual contributions by the potential driving agents, solar variability being one of them.

Solar UVB irradiance in Innsbruck — January to May 1993-96

open access: yesMeteorologische Zeitschrift, 1997
The effects of changes of ozone on the erythemal effective irradiance in Innsbruck have been studied for the periods January to May 1993-96. These periods are characterized by large variability in total ozone (e.g. spring 1994). Daily totals of erythemal
