Solar Influence on Global and Regional Climates (2012, methodology): “However, recent observations of the descent into the current ‘‘unusual’’ (for the space age) solar minimum (Lockwood 2010) cast doubt on this as they show more variability in the UV and considerable change in spectral shape (Harder et al. 2009).”
Solar forcing of winter climate variability in the Northern Hemisphere (2011, background): “Spectral Irradiance Monitor satellite measurements indicate that variations in solar ultraviolet irradiance may be larger than previously though”
What is the current state of scientific knowledge with regard to seasonal and decadal forecasting? (2012, background): “Furthermore, recent satellite observations suggest that changes in UV radiation may be much larger than previously thought (Harder et al 2009).”
SOLAR INFLUENCES ON CLIMATE (2010, unknown): “…suggest that over the declining phase of the solar cycle between 2004 and 2007 there was a much larger (factor of 4–6) decline in UV than indicated in Figure 3, and this is partially compensated in the TSI variation by an increase in radiation at visible wavelengths [Harder et al., 2009].”
SEMIEMPIRICAL MODELS OF THE SOLAR ATMOSPHERE. III. SET OF NON-LTE MODELS FOR FAR-ULTRAVIOLET/EXTREME-ULTRAVIOLET IRRADIANCE COMPUTATION (2009, background): “However, changes of the areas not identified as magnetically “active” in the images used are possible, and according to SORCE/SIM observations over the decay of the last solar cycle (Harder et al. 2009) these changes are likely.”
Recent variability of the solar spectral irradiance and its impact on climate modelling (2012, methodology): “This situation changed with the launch of the Spectral Irradiance Moni-120 tor instrument (SIM, Harder et al., 2005a) onboard the Solar Radiation and Climate Experiment satellite (SORCE, Rottman, 2005) in 2003, which was shortly after the most recent maximum of solar activity.”
Reconstruction of total and spectral solar irradiance from 1974 to 2013 based on KPVT, SoHO/MDI and SDO/HMI observations (2014, background): “In the case of SSI, gaping disagreements between models and observations persist, exemplified in the current debate on the overall trends in the SORCE/SIM record (Harder et al. 2009; Lean & DeLand 2012; Unruh et al. 2012; Wehrli et al. 2013; Ermolli et al. 2013).”
Anthropogenic and Natural Radiative Forcing (2014, background): “The Spectral Irradiance Monitor (SIM) on board SORCE (Harder et al., 2009) shows, over the SC 23 declining phase, measurements that are rather inconsistent with prior understanding, indicating that additional validation and uncertainty estimates are needed (DeLand and Cebula, 2012; Lean and Deland, ”
Solar change and climate: an update in the light of the current exceptional solar minimum (2010, background): “…current solar minimum from the Spectral Irradiance Monitor (SIM) on SORCE give a radically different picture, with 1 W m − 2 coming from this range and upward and downward trends in other wavebands cancelling to a large extent and giving a net contribution of only 0.3 W m − 2 (Harder et al. 2009).”
CMIP5 historical simulations (1850–2012) with GISS ModelE2 (2014, methodology): “Recent observations of out-of-phase behavior [Harder et al., 2009] remain to be confirmed [Lean and Deland, 2012], and were not used in this study.”
Solar Irradiance Variability and Climate (2013, background): “However, there is some doubt about the reality of the extreme spectral dependence of irradiance variations found by Harder et al. (2009); see DeLand & Cebula (2012), Ermolli et al. (2012) and Sects.”
