Correction Strategies

Abstract Over a half-billion smartphones are now capable of measuring atmospheric pressure, potentially providing a global surface observing network of unprecedented density and coverage. An earlier study by the authors described an Android app, uWx, that served as a test bed for advanced quality control and bias correction strategies. To evaluate the utility and quality of the resulting smartphone pressure observations, ensemble data assimilation experiments were performed for two case studies over the Pacific Northwest. In both case studies, smartphone pressures improved the analyses and forecasts of assimilated and nonassimilated variables. In case I, which considered the passage of a front across the region, cycled smartphone pressure assimilation consistently improved 1-h forecasts of the altimeter setting, 2-m temperature, and 2-m dewpoint. During a postfrontal period, cycled smartphone pressure assimilation improved mesoscale forecasts of hourly precipitation accumulation. In case II, which considered a major coastal windstorm, cycling experiments assimilating smartphone pressures improved 10-m wind forecasts as well as the predicted track and intensity. For both cases, free-forecast experiments initialized with smartphone data produced forecast improvements extending several hours, suggesting the utility of crowdsourced smartphone pressures for short-term numerical weather prediction.

Over Time

A growing number of case studies have painted a picture of a burgeoning network of subnational and cross-border regional environmental linkages along the Canada-United States border, a development which may indicate an evolution in governance arrangements such that cross-border environmental policy spaces are being created. In addition to increasing in number, this literature suggests that cross-border interactions have become more formalized, more functionally intense and increasingly multilateral, or regional, in orientation. This paper explores in a comprehensive, cross-regional manner the finding of these case studies with regard to the extent and intensity of subnational activity by examining the findings of a 2005 survey of environmental linkages between states and provinces along the Canada-U.S. border. The survey findings indicate that subnational and regional interactions have been institutionally and functionally ‘intact’ for longer than most observers of Canada-U.S. environmental relations might expect. One of the most interesting findings is that subnational and regional cross-border environmental linkages, contrary to conventional wisdom, have become more numerous over time but not necessarily more intense in functional terms. Moreover, as expected, environmental linkages are clearly regionally concentrated; clusters of highly linked states and provinces can be found along the Canada-U.S. border, particularly in New England, the Great Lakes and the Pacific Northwest. Each of the clusters – or environmental regions – exhibits unique characteristics in terms of the extent and intensity of cross-border linkages.
