EVALUATION OF THE OPERATIONAL OZONE FORECAST MODEL OF THE ZAMG WITH MEASUREMENTS OF THE AUSTRIAN AIR QUALITY NETWORK

Operational model forecasts of ozone concentrations are compared to the observations of about 150 air quality stations in Austria. Evaluations of the last three summers revealed that exceedances of the information threshold could be predicted quite well by the model. Investigation of a heat period in summer 2006 indicates possible sources of precursors. The Lagrangian particle model LASAT (www.janicke.de) is used additionally to the chemical model CAMx (www.camx.com) to show the dispersion of the plumes of stacks with high emissions of NOx in the vicinity of Vienna. For two months in summer 2007 sensitivity studies with different input parameters were performed. Model runs with different parameterisations for the vertical diffusion coefficient (Kv) are conducted and experiments with different values of the minimum values of Kv in the lower levels show the influence of this parameter on the nocturnal ozone decrease for different sites. Different model runs with variable boundary conditions at the top of the modelling domain as well as variable total ozone column data are performed

IIASA/EQU Justice Framework: A descriptive guideline for science and policy

The consideration of justice has become a critical area of focus for researchers, as awareness is increasing that (perceived) injustices are a main barrier for effectively tackling the interconnected global grand challenges, such as the climate and the biodiversity crises. Insufficient attention to perceptions of justice is a major issue slowing progress on climate change and other major policy issues. Justice, however, is difficult to grasp as it is a multi-dimensional and culturally diverse term and is in many instances of global socio-environmental issues not formally institutionalized. This working paper introduces the first version of the IIASA/EQU justice framework, which comprehensively outlines justice in its multiple aspects with the aim to facilitate justice assessment across diverse research and policy contexts. It is thus a descriptive framework with no normative objectives. The framework is grounded in philosophy and is applied and tested in a variety of applications, to be useful for research and decision-making. It is meant to be accessible across disciplines, powerful in terms of capacity to express a variety of justice ideas, and modular so researchers can select and deploy the aspects that are most appropriate or useful. The framework as presented here serves as a baseline for further refinement, expansion, applications, and evaluation across disciplines, subject areas, and cultural backgrounds
