Solar irradiance refers to the amount of energy from the Sun that reaches a specific area on Earth. It measures the intensity of sunlight and is an important factor in understanding solar energy and its impact on our planet. Full definition
We obtained a large historical solar forcing between the Maunder minimum and the present, as well as a significant increase in solar irradiance in the first half of the twentieth - century. (aanda.org)
Total solar irradiance changes, though of small magnitude, do appear to affect sea surface temperatures (SSTs), most obviously at latitudes where cloud cover is small and irradiance is abundant, such as the Northern Hemisphere subtropics during summer. (giss.nasa.gov)
We also demonstrate that SPM data can be employed to reconstruct total solar irradiance variations with almost the same accuracy as recently shown for MDI data. (aanda.org)
