Abstract: We continue former work on the modeling of potential effects of Gamma RayBursts on Phanerozoic Earth. We focus on global biospheric effects of ozonedepletion and show a first modeling of the spectral reduction of light by NO2formed in the stratosphere. We also illustrate the current complexitiesinvolved in the prediction of how terrestrial ecosystems would respond to thiskind of burst. We conclude that more biological field and laboratory data areneeded to reach even moderate accuracy in this modeling
