“…Our concentrations are higher than those measured at some eastern US sites determined with bulk or total deposition sampling techniques (e.g., DIXON et al, 1996;HENDRY and BREZONIK, 1980;LUO et al, 2002;PETERS and REESE, 1995;RICHTER, RALSTON, and HARMS, 1983;YANG et al, 1996) and lower that those measured at other eastern US sites (BUDA and DEWALLE, 2002;ITO, MITCHELL, and DRISCOLL, 2002;KELLY et al, 2002). Our data clearly show higher nitrate concentrations at inland sites.…”

“…The composition of precipitation and its relationship to meteorological parameters have been explored through a variety of statistical approaches. Examples include time-series analyses using linear and nonlinear regression techniques (Buda and DeWalle, 2002;Seto et al, 2002;Nickerson and Madsen, 2005), cluster and principalcomponent analyses (e.g. Dorling et al, 1992;Cana-Cascalar, 2002), and spatial-pattern analyses of atmospheric circulation (Davies et al, 1991;Yarnal, 1991Yarnal, , 1993Dorling et al, 1992;Lamb, 2003, 2005).…”

Precipitation chemistry data from the National Atmospheric Deposition Program were related to weather data from the Climate Diagnostics Center in order to reveal the influence of large-scale circulation patterns on the wet deposition of sulfate downwind of the Ohio River Valley, where SO 2 emissions were curtailed sharply in the mid-1990s. The chemistry data from five precipitation-sampling sites were combined to provide a regional average for each summer season over the 21-year period from 1984 to 2004. The long-term trend of sulfate concentration is associated to a statistically significant extent by composited flow patterns associated with the East Pacific-North Pacific index. The regional weather pattern for the sulfate-rich years is associated with an intensification of the Bermuda High over the southeastern United States at the surface in tandem with a weakening of the 500-hPa geopotential height (GPH) climatological trough located over the northeastern United States. The highest-sulfate concentration days for the Atmospheric Integrated Research Monitoring Network (AIRMoN) Pennsylvania site occurred during a similar synoptic pattern when intense convection over the eastern United States was favoured thermodynamically. This study suggests that temporal changes in the large-scale circulation pattern over North America need to be considered, in addition to changes in precursor emissions, as an explanation for the decreases in sulfate concentrations observed in summertime rains across the eastern United States.

“…An observational network of soil moisture, evapotranspiration, groundwater, and lateral water fluxes (surface and subsurface) that is on par with the network of precipitation and stream gages should improve our overall understanding of the total movement of water in the Earth system. For example, fluxes of pollutants from the atmosphere may be affected by the combined effects of temperature and precipitation changes predicted for the Mid-Atlantic region [Buda and DeWalle, 2002]. Even if an extensive hydrologic network is built, however, hydrologists are faced with the problem of forecasting hydrologic regimes and shifts that have not been previously observed.…”

The increasing expression of human activity, climate variability, and climate change on humid, terrestrial hydrologic systems has made the integrated nature of large river basins more apparent. However, to date, there is no instrument platform sufficient to characterize river basins' hydrologic couplings and feedbacks, with many processes and impacts left almost entirely unobserved (e.g., snowmelt floods). Characterization at the river basin scale will require a more holistic vision and a far greater commitment from the environmental science community. It will require new designs and implementation of integrated instrumentation, a new generation of models, and a management framework that clearly addresses the human‐climate‐terrestrial interactions impacting our watersheds and river basins. Initially, we propose that existing “similarity classifications” (e.g., regional soil, geologic, ecologic, hydrographic digital products) can provide a starting point for organizing historical data and initiating a long‐term adaptive, multiscale observing strategy. This vision paper outlines instrumentation platforms for point, plot, reach, and hillslope scales that could be located within the “characteristic” landscapes of river basins. The network of observing platforms then forms the basis of a “Hydro‐Mesonet” that can potentially support multiscale, multiprocess scientific studies necessary to understand and improve forecasts of our water resources at the river basin scale. This paper concludes with a discussion of how a network of such sites can support research at the level of the individual researcher and scale to the level of community‐wide initiatives.
