The Loneliest Young Star

An unusual celestial object called CX330 was first detected as a source of X-ray light in 2009. It has been launching “jets” of material into the gas and dust around it.

The Measurement and modeling of the contribution of ammonia to total nitrogen deposition from canopy to regional scale

In North America, ammonia (NH3) is increasingly being recognized not only for its role in atmospheric aerosol formation but also as an important component of atmospheric nitrogen deposition. This has been driven by the evolution of policies to protect ecosystems from nitrogen over-enrichment, an expansion of research underpinning these policy efforts, and technological advances in measurement and modeling tools applied to these research needs. Ammonia measurements from satellites, nitrogen focused field campaigns, and the National Atmospheric Deposition Program’s Ammonia Monitoring Network (AMoN) have advanced understanding of the processes controlling NH3 air-surface exchange and the spatio-temporal behavior of NH3 in the atmosphere. These datasets have subsequently lead to improvements in NH3 air-surface exchange models and therefore more accurate estimates of NH3 deposition. From a process standpoint, NH3 differs from other nitrogen compounds such as nitric acid in that NH3 is exchanged bi-directionally between the surface and atmosphere as regulated by a “compensation point”. Because natural surfaces may be sources or sinks of atmospheric NH3, and may alternate between emission and deposition on a timescale as short as hours, the deposition velocity concept does not accurately describe NH3 air surface exchange. Instead, a more mechanistic treatment of the nitrogen status and acidity of the surface must be employed, typically as a bi-directional framework that partitions the biosphere into atmosphere, vegetation and ground components. Versions of this modeling framework have been successfully applied in canopy to regional scale modeling assessments of NH3 emission and deposition and to assess the importance of NH3 within the overall N deposition budget. This talk will present recent process-level NH3 flux measurements and review advances in canopy- to regional-scale modeling of NH3 air-surface exchange. Examples of nitrogen deposition budgets, developed from measurements and modeling, that illustrate the contribution of NH3 to total N deposition across a range of ecosystem and atmospheric chemical environments will also be presented.

Optimizing Resource and Energy Recovery for Municipal Solid Waste Management

Significant reductions of carbon emissions and air quality impacts can be achieved by optimizing municipal solid waste (MSW) as a resource. Materials and discards management were found to contribute ~40% of overall U.S. GHG emissions as a result of materials extraction, transport, collection, processing, recycling, composting, combustion, and landfilling. Decisions affecting materials management today are generally either fiscally based or on the presumption of favorable outcomes without an understanding of the environmental tradeoffs. However, there is a growing demand to better understand and quantify the net environmental and energy trade-offs in setting waste management goals and priorities at a state and local level. This presentation will describe a 2nd generation tool being developed through the ACE RAP for SEM 1.2

Impact of Satellite Remote Sensing Data on Simulations of Coastal Circulation and Hypoxia on the Louisiana Continental Shelf

We estimated surface salinity flux and solar penetration from satellite data, and performed model simulations to examine the impact of including the satellite estimates on temperature, salinity, and dissolved oxygen distributions on the Louisiana continental shelf (LCS) near the annual hypoxic zone. Rainfall data from the Tropical Rainfall Measurement Mission (TRMM) were used for the salinity flux, and the diffuse attenuation coefficient (Kd) from Moderate Resolution Imaging Spectroradiometer (MODIS) were used for solar penetration. Improvements in the model results in comparison with in situ observations occurred when the two types of satellite data were included. Without inclusion of the satellite-derived surface salinity flux, realistic monthly variability in the model salinity fields was observed, but important inter-annual variability wasmissed. Without inclusion of the satellite-derived light attenuation, model bottom water temperatures were too high nearshore due to excessive penetration of solar irradiance. In general, these salinity and temperature errors led to model stratification that was too weak, and the model failed to capture observed spatial and temporal variability in water-column vertical stratification. Inclusion of the satellite data improved temperature and salinity predictions and the vertical stratification was strengthened, which improved prediction of bottom-water dissolved oxygen. The model-predicted area of bottom-water hypoxia on the Louisiana shelf, an important management metric, was substantially improved in comparison to observed hypoxic area by including the satellite data.

Gross Domestic Product by State, 1st quarter 2016

Real gross domestic product (GDP) increased in 37 states and the District of Columbia in the first quarter of 2016, according to statistics on the geographic breakout of GDP released today by the Bureau of Economic Analysis. Real GDP by state growth, at an annual rate, ranged from 3.9 percent in Arkansas to -11.4 percent in North Dakota. Construction; health care and social assistance; and retail trade were the leading contributors to U.S. economic growth in the first quarter. Full Text
