A comparison of stratospheric photochemical response to different reconstructions of solar ultraviolet radiative variability

摘要: Abstract We present calculations of stratospheric chemical abundances variations between different levels solar activity using a simple photochemistry model in transient chemistry mode. Different models for the reconstruction spectrum, as well observations from SOLar STellar Irradiance Comparison Experiment (SOLSTICE) and Spectral Monitor (SIM) on SOlar Radiation Climate (SORCE) satellite, are used inputs to calculations. put emphasis MOnte CArlo Solar Model (MOCASSIM) reconstructions, which cover spectral interval 150 400 nm extend 1610 present. compare our results with those obtained Naval Research Laboratory (NRLSSI) Magnesium-Neutron (MGNM) over period time spanning ascending phase Cycle 22. also perform SORCE composite spectra descending 23 reconstructed MOCASSIM, NRLSSI MGNM same comparison. Finally, we Maunder Minimum minimum (in March 2009) find that ozone concentration was slightly higher during recent minimum, consequent small positive variability MOCASSIM both epochs, especially below 260 nm. response is not only dependent amplitude spectrum (especially 200–240 nm band), but significantly base level spectrum.
