Total Solar Irradiance
MetadataShow full item record
A possible long term trend of the total solar irradiance could be a natural cause for climate variations on Earth. Measurement of the total solar irradiance with space radiometers have started in 1978. We present a new total solar irradiance composite, with an uncertainty of +/- 0.35 W/m2. From the minimum in 1995 to the maximum in 2002 the total solar irradiance increased by 1.6 W/m2. In between the minima of 1987 and 1995 the total solar irradiance increased by 0.15 W/m2.
