Surface-level ozone causes serious health impacts in humans and damages crops and terrestrial ecosystems. High concentrations of ozone are due to a combination of photochemistry, dynamics, and background or long range transport of pollutants. As discussed in the NESCAUM report (NESCAUM, 2006), ""Scientific studies have...

Traditional surface-based particle pollution measurements are the basis for compliance assessment, but they have limited spatial coverage. Satellites can provide much broader coverage, but they currently do not offer extensive particle vertical distribution information, and cannot distinguish among spherical aerosol compositions without calibration by ground...

Proposal Summary. We will apply OMI remote sensing information to air quality issues in the eastern US, where NO2 and SO2 are key precursors to O3 and particulate matter (PM) - USEPA designated health and environmental problems. The goal of this research is a deeper...

Our objective is to estimate seasonal snow volumes, relative to historical trends and extremes, in snow-dominated mountains that have austere infrastructure, sparse gauging, challenges of accessibility, and emerging or enduring insecurity related to water resources. To judge feasibility, the proposed effort looks at two regions...

Droughts and their hydrological consequences are a major threat to food security throughout the world. In arid and semiarid regions dependent on irrigated agriculture, prolonged droughts lead to significant and recurring economic and social losses. In this Feasibility Stage 1 project, the assembled research and...

The period immediately following an environmental disaster typically involves a rush by decision makers and scientists, to determine what data are relevant and to access these data for disaster mitigation and post-event analysis. The University of Alabama in Huntsville has prototyped and demonstrated Event-Driven Data...

Event-Driven Data Delivery (ED3) technology addresses the problem of data preparedness for disaster events. In the Stage 1-Feasibility study, the team created a flexible, loosely coupled ED3 Framework, and through reference implementations of the various components, successfully demonstrated how the technology can be applied to...

Objectives: We propose to develop a widely needed on-line portal that will streamline the co-registration of animal tracking data with a variety of weather and land surface data. The portal will also provide toolboxes for data visualization and analysis. To ensure relevance and effectiveness, the...

Climate change poses severe threats to biodiversity, and conservationists have to adapt their management decisions to a changing climate. The challenge is that the biological response to future climate change is uncertain. Climate change will entail a general warming, but even more importantly may increase...
