Over the past decade, much of the western U.S. has experienced unusual climate patterns ranging from multi-year droughts to cool-wet springs. Substantial year-to-year variability complicates planning for agricultural producers, and makes it difficult to apply standard rule-of-thumb approaches to irrigation management. While this variability can...

This study will support environmental public health tracking programs by utilizing aerosol optical depth (AOD) data from NASA's Terra and Aqua satellites to create fine particulate matter (PM2.5) datasets that reflect the spatial and temporal variations in ambient PM2.5 concentrations that occur on local scales...

The objective of the project is to test the feasibility of using NASA Earth Science research results to improve decision-making activities by U.S. and foreign governments and international agencies through scientifically rigorous national- and global-level environmental indicators. The Millennium Challenge Corporation (MCC) relies on environmental...

In line with the NRC?s Decadal Survey, NASA is planning the HyspIRI mission, where a hyperspectral imager will be launched in approximately 2013. The purpose of HyspIRI is to characterize land surface composition and vegetation types for ecosystem health. In order to better prepare end-users...

Cladophora is a filamentous, green alga that grows attached to solid substrate in all of the Laurentian Great Lakes. Nuisance growth of Cladophora occurs lakewide in comparatively phosphorus-rich shallow waters (0-15m depth) possessing solid substrate, and has recently become a prominent Great Lakes ecological and...

In the wake of severe weather events, the National Weather Service (NWS) needs to acquire detailed, highly perishable data necessary for conducting post-event analysis. The process requires the rapid deployment of trained teams to gather damage evidence (e.g., storm debris damage patterns) that can be...

The Gulf of Mexico Alliance has developed a Governors Action Plan for the five Gulf of Mexico states to address coastal ecological and societal issues. An element of that plan is to develop EPA mandated nutrient criteria for the estuaries around the Gulf of Mexico...

Emissions from fire, including agricultural and rangeland burning, forest fires, and peatland fires, impact the atmosphere dramatically. Current tools to quantify emission sources are developing quickly in a response to the need by the modeling community to assess fires role in carbon cycling and impact...

Climate affects the geographic distribution of species. In the Pacific Northwest Region, the snowpack has been significantly reduced and the summer drought period extended since the 1970s. As a result, forests have become more susceptible to outbreaks of insects, diseases, and fire. These disturbances are...

This proposal will investigate the feasibility of methodologies for reconciling the current NASA MODIS 500m burned area and the MODIS 1km active fire product to provide improved burned biomass [units kg] and associated uncertainty estimates. The objective is to contribute to domestic air quality monitoring...
