TL;DR
This paper models the potential global biospheric effects of Gamma Ray Bursts on Earth, focusing on ozone depletion and light reduction, highlighting the need for more biological data for accurate predictions.
Contribution
It provides a first model of spectral light reduction by NO2 and discusses the complexities in predicting ecosystem responses to Gamma Ray Bursts.
Findings
NO2 formation leads to spectral reduction of sunlight
Ecosystem response prediction is highly complex
More biological data is needed for accurate modeling
Abstract
We continue former work on the modeling of potential effects of Gamma Ray Bursts on Phanerozoic Earth. We focus on global biospheric effects of ozone depletion and show a first modeling of the spectral reduction of light by NO2 formed in the stratosphere. We also illustrate the current complexities involved in the prediction of how terrestrial ecosystems would respond to this kind of burst. We conclude that more biological field and laboratory data are needed to reach even moderate accuracy in this modeling
