2 2 TSI Observations C. Fröhlich

3 TSI and Sunspots

4 8/21/20084 TSI Reconstruction from Surface Images Daily values Surface Images (High Cadence) Semi-empirical model with main assumption: B-field at solar surface causes TSI + SSI variations Components: Spots (contin. images), faculae + network (magnetograms), quiet Sun Model atmospheres 1 free parameter

5 8/21/20085 Filling factors

6 8/21/20086 Filling factors of the five component model Quiet Sun ( q ) Sunspot Umbra ( u) sunspot penumbra ( p ) Faculae + Network ( f )
