Poor air quality is recognised as the most important environmental health issue of our time. Meteorological variables like temperature and wind speed can strongly influence air quality and these variables often show clear annual cycles. It is therefore common to analyse atmospheric pollutants within a seasonal framework. However, the commonly used seasons in Australia do not align well with all of the most important annual weather patterns that influence air quality in the Sydney Basin. We used Indigenous perspectives on 'seasons' as identified by the co-authors and combined these with statistical analysis of the local climatology. This enabled us to create a set of locally informed 'quasi-seasons' that we named IKALC-seasons (Indigenous Knowledge Applied to Local Climatology). Engaging with the IKALC-seasons improved our understanding of temporal variability of air pollution in western Sydney, mainly due to a better identification of the time of year when cold, still weather conditions result in higher levels of fine particulate pollution, carbon monoxide and nitrogen oxides. Although the IKALC seasons identified in this study are intrinsically local in nature, the methodology developed has broadscale application. This approach can be used to identify the times of year when micrometeorological conditions are most likely to drive poor air quality thereby helping to inform effective decision-making about emission controls.
This article describes some of the work of the European Community funded project — Communication and Access to Information for People with Special Needs in the (CAPS) Programme Technology Initiative for Disabled and Elderly (TIDE). CAPS is developing ways of increasing access to information for a significant group of handicapped and elderly persons who have difficulty in accessing the printed word. The print disabled group includes the blind, the deaf blind, the visually impaired, the dyslexic and those with motor impairments which make it difficult to control paper documents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
