Atmospheric PhysicsProvides graduate training and research within the atmospheric sciences and associated fields. This complicates the analysis of the SIM observations as a result of solar-cycle variability of the total solar irradiance, which is significantly better recognized than adjustments in wavelength-resolved irradiance, and which is reproduced by models equivalent to Lean’s, cannot be used to assess the validity of the observations.

Even if this is not the case, it will likely be necessary to reconcile the implications of the SIM observations with earlier analyses of ozone modifications in the course of the eleven-year solar cycle that aren’t in line with the implied effects of SIM-like irradiance modifications.

By contrast, SIM (proven in blue) measures modifications of as much as 5 mW m−2 nm−1 at UV wavelengths, and −1.5 mW m−2 nm−1 within the seen vary past four hundred nm. Although the irradiance modifications measured by SIM are very different from these predicted by the model at almost all wavelengths, when these adjustments are integrated across the spectrum, they yield similar changes in the complete downward photo voltaic flux on the top of Earth’s environment for 2004 minus 2007 (0.09 W m−2 for SIM and 0.eleven W m−2 for Lean’s model).
