Modelling the effect of size on the aerial dispersal of microorganisms

Edward Mitchell, Isabelle Bey, Symeon Koumoutsaris

Aim We investigate the long-standing question of whether the small size of microbes allows most microbial species to colonize all suitable sites around the globe or whether their ranges are limited by opportunities for dispersal. In this study we use a mod ...

Influence of El Nino-Southern Oscillation on the interannual variability of tropospheric ozone in the nothern midlatitudes

Isabelle Bey, Sylvia Generoso, Symeon Koumoutsaris

We use the GEOS-Chem model to interpret long-term measurements of tropospheric

Interannual variability in tropospheric ozone and its precursors : a modeling study constrained by long-term ground-based and satellite observations

Symeon Koumoutsaris

Tropospheric ozone (O3) is a harmful pollutant and an increasingly important green-house gas. Tropospheric O3 distributions are determined by complex and non-linear interactions between photochemistry and transport processes. The first objective of this th ...
