In recent years it became evident that our earth system is influenced by the sun in a quite complex way. The solar signal is deposited and redistributed in the atmosphere from the ocean surface and below up to the thermosphere by various mechanisms like absorption of radiation and particles, generation, modulation, and transport of photochemically active species, excitation and propagation of waves at various spatial and temporal scales. Both solar influences as well as changes in greenhouse gases from man-made activities or natural sources have been important in understanding climate variability on decadal and longer time scales. This one-day seminar will cover various aspects that are relevant for a better understanding of the interaction between our sun and the earth system.

Talks that cover the following topics are cordially invited:

• solar atmosphere, solar output, and their variation
• observation and modelling of solar variability
• magnetic interaction between sun and earth (space weather)
• impact of solar (and decadal) variability on the climate system from the past to the present
• solar influences on dynamical and chemical processes in the ocean and atmosphere

It is planned to have one or two main speakers (35-45 min) and several extended talks from 20 to 30 min. If you are interested to give a presentation, please contact mark.weber@uni-bremen.de (Tel. 0421/218-2362) and submit your name, and title of your presentation.
