Description: Das Projekt "Towards an improved understanding of the Global Energy Balance: absorption of solar radiation" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: Eidgenössische Technische Hochschule Zürich, Institut für Atmosphäre und Klima.The genesis and evolution of Earth's climate is largely regulated by the balance between inflow of solar energy (received from the Sun) and outflow of thermal energy (emitted by the Earth). Human interference with climate occurs first of all through a perturbation of this energy balance, as a result of anthropogenic modification of greenhouse gas and aerosol concentration. Changes in the global energy balance affect not only global warming, but also other aspects of climate change, such as the intensity of the water cycle, snow cover and glacier retreat, plant productivity and terrestrial carbon uptake. Despite the central importance of the global energy balance for the climate system and climate change, substantial uncertainties still exist in the quantification of its different components and their decadal variations. The long-term research goal of the investigators aims at an improved understanding of the mean state and the spatio-temporal variations of the global energy balance. While our knowledge on the energy exchange between Sun, Earth and space has recently been improved through new satellite programs, the distribution of radiative energy within the climate system, which cannot directly be measured by satellites, is still afflicted with large uncertainties. The present project aims at reducing the uncertainties in the absorption of solar radiation within the climate system, a crucial component of the global energy balance, through an optimal usage of the information contained in worldwide surface and satellite measurements. These investigations should allow for the best possible estimates on the disposition of solar radiation in the climate system. Such estimates are urgently needed for a better understanding and representation of the global energy balance in the framework of the 5th IPCC assessment report, and for the assessment and improvement of climate models.
