Tsallis’ q-triplet and the ozone layer

Keywords: Nonextensive statistical mechanics Meta-stable states Mixing Weak chaos q-triplet Stratospheric ozone a b s t r a c t Tsallis' q-triplet [C. Tsallis, Dynamical scenario for nonextensive statistical mechanics, Physica A 340 (2004) 1–10] is the best empirical quantifier of nonextensivity. Here we study it with reference to an experimental time-series related to the daily depth-values of...

Stratospheric ozone and health.

BACKGROUND Stratospheric ozone is being depleted and ambient ultraviolet (UV) irradiance is probably increasing. While remedial steps have been taken through the Montreal protocols, at best it will take some 90 years for stratospheric ozone concentrations to return to the levels existing in the 1970s. METHODS The evidence that these changes may have harmful effects on health has been reviewed...
