Towards a long-term record of solar total and spectral irradiance
N. A. Krivova, S. K. Solanki, Y. C. Unruh
The variation of total solar irradiance (TSI) has been measured since 1978 and that of the spectral irradiance for an even shorter amount of time. Semi-empirical models are now ava…
ACRIM-gap and total solar irradiance revisited: Is there a secular trend between 1986 and 1996?
N. A. Krivova, S. K. Solanki, T. Wenzler
A gap in the total solar irradiance (TSI) measurements between ACRIM-1 and ACRIM-2 led to the ongoing debate on the presence or not of a secular trend between the minima preceding…
Reconstructed and measured total solar irradiance: Is there a secular trend between 1978 and 2003?
T. Wenzler, S. K. Solanki, N. A. Krivova
Total solar irradiance reconstructed between 1978 and 2003 using solar surface magnetic field distributions is compared with three composites of total solar irradiance measurements…
Reconstruction of solar UV irradiance since 1974
N. A. Krivova, S. K. Solanki, T. Wenzler +1
Variations of the solar UV irradiance are an important driver of chemical and physical processes in the Earth's upper atmosphere and may also influence global climate. Here we reco…
A homogeneous database of sunspot areas covering more than 130 years
L. Balmaceda, S. K. Solanki, N. Krivova +1
The historical record of sunspot areas is a valuable and widely used proxy of solar activity and variability. The Royal Greenwich Observatory (RGO) regularly measured this and othe…
