A new, lower value of total solar irradiance: Evidence and climate significance

Lean, Judith L.; Kopp, Greg

The most accurate value of total solar irradiance during the 2008 solar minimum period is 1360.8 ± 0.5 W m^-2 according to measurements from the Total Irradiance Monitor (TIM) on NASA's Solar Radiation and Climate Experiment (SORCE) and a series of new radiometric laboratory tests. This value is significantly lower than the canonical val…

The minimal solar activity in 2008-2009 and its implications for long-term climate modeling

Schrijver, C. J.; Mewaldt, R. A.; Woods, T. N. +1 more

Variations in the total solar irradiance (TSI) associated with solar activity have been argued to influence the Earth's climate system, in particular when solar activity deviates from the average for a substantial period. One such example is the 17th Century Maunder Minimum during which sunspot numbers were extremely low, as Earth experienced the …
