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

INTRODUCTION OF CLOUDS IN DART MODEL [PDF]
The 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 ...

Journal 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),

Journal 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 ...

Observations and modelling of total and spectral solar irradiance [PDF]
, 2012 The variation of solar energy entering Earth’s atmosphere, the solar irradiance, is an important influence on the Earth’s climate. Total output of the Sun varies by 0.1% over an 11-year solar cycle and on longer, secular scales there still remains ...

Solar Irradiance Variability: Comparisons of Models and Measurements
Earth 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 ...

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

A Reconstruction of Total Solar Irradiance Based on Wavelet Analysis
Earth and Space Science, 2021 As an important indicator of solar activity, the long‐term total solar irradiance (TSI) observations are needed to uncover the impact of solar activity on Earth's climate.
