Ozone contamination in aircraft cabins: Objectives and approach

Three panels were developed to solve the problem of ozone contamination in aircraft cabins. The problem is defined from direct in-flight measurements of ozone concentrations inside and outside airliners in their normal operations. Solutions to the cabin ozone problem are discussed under two areas: (1) flight planning to avoid high ozone concentrations, and (2) ozone destruction techniques installed in the cabin air systems

Global measurements of gaseous and aerosol trace species in the upper troposphere and lower stratosphere from daily flights of 747 airliners

Extensive measurements include ozone, carbon monoxide, water vapor, and aerosol and condensation nuclei number density. Less extensive measurements include chlorofluoromethanes, sulfates and nitrates. Certain meteorological and flight information are also recorded at the time of these measurements. World routes range in latitude from about 60 deg N near North America to about 40 deg S over Australia and 23 deg S over South America. Typical data show significant changes in ozone, carbon monoxide, and water vapor when crossing the tropopause either during changes in altitude or at cruise altitude. These gases as well as light scattering particles and condensation nuclei exhibit considerable variability along a flight route

Ozone Contamination in Aircraft Cabins: Summary of recommendations

Recommendations from the three panels on in-flight measurements, flight planning to avoid high ozone, and ozone destruction techniques are summarized

Ozone Contamination in Aircraft Cabins. Appendix B: Overview papers. In-flight measurements

The NASA Global Atmospheric Sampling Program ozone measurements were obtained to establish to characteristics of the ambient ozone concentration during routine operations and to determine the attenuation of ambient concentrations of cabin air systems from simultaneous ambient and in cabin measurements. The characteristics of ambient ozone include: (1) maximum concentration; (2) duration of ozone encounters; (3) frequency of ozone during a flight; (4) variability of ozone during a flight; (5) in relation to routes, altitude, and meteorological conditions

Gender Justice and Climate Justice: Community-based strategies to increase women’s political agency in watershed management in times of climate change

Socially vulnerable people, and women in particular, are disproportionately affected by global climate change because of their gendered socioeconomic roles and often their geographic location; yet they are least equipped to deal with those impacts due to their disadvantaged economic and political position. Women, however, have special contributions to make towards climate change adaptation because of gendered differences in positional knowledge of ecological and water-related conditions. To date, women have been largely underrepresented, and in the majority of cases, excluded from formal decision-making processes related to climate change mitigation and adaptation. Including women in these processes and building their capacity and resilience is required for the development of effective and gender-sensitive climate change adaptation policy. Also, preparing women for the short and long-term impacts of climate change is crucial for addressing some of the social aspects of this phenomenon and for preventing further aggravation of existing gender inequalities. This paper discusses South-North initiatives and models for community-based environmental and climate change education which are using the democratic opening provided by watershed-based governance structures to broaden grassroots participation, especially of women, in political processes. We outline the activities and results of two international projects, the Sister Watersheds project, with Brazilian and Canadian partners (2002-2008), and a Climate Change Adaptation in Africa project with partners in Canada, Kenya, Mozambique, and South Africa (2010-2013)

Dual arm master controller development

The advanced servomanipulator (ASM) slave was designed with an anthropomorphic stance gear/torque tube power drives, and modular construction. These features resulted in increased inertia, friction, and backlash relative to tape driven manipulators. Studies were performed which addressed to human factor design and performance tradeoffs associated with the corresponding master controller best suited for the ASM. The results of these studies, as well as the conceptual design of the dual arm master controller, are presented

Women and water management in times of climate change: participatory and inclusive processes

This paper focuses on community engagement, and particularly the inclusion of women, in water management as a response to climate change. Addressing water-related problems is central to climate change adaptation, and civil society, marginalized populations and women, in particular, must be involved. This is for both moral and pragmatic reasons: not only are the marginalized the first and worst affected by extreme weather events, but they also possess local ecological, social and political knowledge which can inform and contribute significantly to climate change adaptation strategies. Because of their social roles and position worldwide, women are greatly affected by water scarcity and flooding, and tend to be gravely impacted by poor water management, yet they face great difficulties in participating effectively in governance bodies. Sustainable long-term management of water resources in the face of climate change requires the participation of women, who possess knowledge of effective social tech- nologies for coping with and adapting to climate change. Community-based environmental education is therefore required in order to expand the equitable involvement of women in water-related climate change adaptation activities and policy development. Environmental non-governmental organizations worldwide, working on shoestring budgets at the local level, are developing a range of methods to organize, raise consciousness and confidence, and help local activists create successful climate defense programs. This paper discusses SoutheNorth initiatives and models for community-based environmental and climate change education which are using the democratic opening provided by watershed-based governance structures to broaden grassroots participation, especially of women, in political processes. We outline the activities and results of two international projects: the Sister Watersheds project, with Brazilian and Canadian partners (2002e2008); and a Climate Change Adaptation in Africa project with partners in Canada, Kenya, Mozambique, and South Africa (2010e2012).This research was supported by the International Development Research Centre, grant number IDRC GRANT NO. 106002-00

International partnerships of women for sustainable watershed governance in times of climate change

This chapter describes and assesses collaborative research with women actively engaged in local and global community engagement processes for water management in times of global climate change. As an equity-focused response to climate change, the interrelated networks and initiatives described in the chapter involve organizations and individuals in Brazil, Mozambique, South Africa, Kenya, and Canada. These collaborations are focused on strengthening low-income women's voices, and legitimizing their knowledge and action within water management institutions and processes. The chapter draws from what people learned through two international projects, the Sister Watersheds project with Canadian and Brazilian partners, and a Climate Change Adaptation in Africa project with partners in Canada, Kenya, Mozambique, and South Africa. The methods and approach of the Sister Watersheds project proved to be applicable to climate change education and organizing in Canada as well as in Brazil. The chapter summarizes that women are working together on climate education and water governance, helping to inspire and generate related strategies.This research was supported by the International Development Research Centre, grant number IDRC GRANT NO. 106002-00

Simultaneous measurements of ozone outside and inside cabins of two B-747 airliners and a Gates Learjet business jet

The average amount of ozone measured in the cabins of two B-747 airliners varied from 40 percent to 80 percent of the atmospheric concentrations without special ozone destruction systems. A charcoal filter in the cabin air inlet system of one B-747 reduced the ozone to about 5 percent of the atmospheric concentration. A Learjet 23 was also instrumented with monitors to measure simultaneously the atmospheric and ozone concentrations. Results indicate that a significant portion of the atmospheric ozone is not destroyed in the pressurization system and remains in the aircraft cabin of the Learjet. For the two cabin configurations tested, the ozone retentions were 63 and 41 percent of the atmospheric ozone concentrations. Ozone concentrations measured in the cabin near the conditioned-air outlets were reduced only slightly from atmospheric ozone concentrations. It is concluded that a constant difference between ozone concentrations inside and outside the cabin does not exist
