Climate implications of carbonaceous aerosols:  An aerosol microphysical study using the GISS/MATRIX climate model (open access)

Climate implications of carbonaceous aerosols: An aerosol microphysical study using the GISS/MATRIX climate model

Recently, attention has been drawn towards black carbon aerosols as a likely short-term climate warming mitigation candidate. However the global and regional impacts of the direct, cloud-indirect and semi-direct forcing effects are highly uncertain, due to the complex nature of aerosol evolution and its climate interactions. Black carbon is directly released as particle into the atmosphere, but then interacts with other gases and particles through condensation and coagulation processes leading to further aerosol growth, aging and internal mixing. A detailed aerosol microphysical scheme, MATRIX, embedded within the global GISS modelE includes the above processes that determine the lifecycle and climate impact of aerosols. This study presents a quantitative assessment of the impact of microphysical processes involving black carbon, such as emission size distributions and optical properties on aerosol cloud activation and radiative forcing. Our best estimate for net direct and indirect aerosol radiative forcing change is -0.56 W/m{sup 2} between 1750 and 2000. However, the direct and indirect aerosol effects are very sensitive to the black and organic carbon size distribution and consequential mixing state. The net radiative forcing change can vary between -0.32 to -0.75 W/m{sup 2} depending on these carbonaceous particle properties. Assuming that sulfates, nitrates and secondary …

Causes of the Financial Crisis (open access)

Causes of the Financial Crisis

The financial crisis that began in 2007 spread and gathered intensity in 2008, despite the efforts of central banks and regulators to restore calm. By early 2009, the financial system and the global economy appeared to be locked in a descending spiral, and the primary focus of policy became the prevention of a prolonged downturn on the order of the Great Depression. This report sets out in tabular form a number of the factors that have been identified as causes of the crisis. The left column of Table 1 below summarizes the causal role of each such factor. The next column presents a brief rejoinder to that argument. The right-hand column contains a reference for further reading.

Iran Sanctions (open access)

Iran Sanctions

This report focuses on the United States' relationship with Iran and how the Obama Administration is handling prior administrations' economic sanctions against Iran. The Obama Administration's policy approach toward Iran has contrasted with the Bush Administration's by attempting to couple the imposition of sanctions to an active and direct U.S. effort to negotiate with Iran on the nuclear issue.

2010 MARINE MICROBES GORDON RESEARCH CONFERENCE (JULY 4-9, 2010 - TILTON SCHOOL, TILTON NH) (open access)

2010 MARINE MICROBES GORDON RESEARCH CONFERENCE (JULY 4-9, 2010 - TILTON SCHOOL, TILTON NH)

Marine microbes include representatives from all three kingdoms of life and collectively carry out virtually all forms of metabolisms found on the planet. Because of this metabolic and genetic diversity, these microbes mediate many of the reactions making up global biogeochemical cycles which govern the flow of energy and material in the biosphere. The goal of this conference is to bring together approaches and concepts from studies of microbial evolution, genomics, ecology, and oceanography in order to gain new insights into marine microbes and their biogeochemical functions. The integration of scales, from genes to global cycles, will result in a better understanding of marine microbes and of their contribution to the carbon cycle and other biogeochemical processes.

Detailed Modeling, Design, and Evaluation of a Scalable Multi-level Checkpointing System (open access)

Detailed Modeling, Design, and Evaluation of a Scalable Multi-level Checkpointing System

High-performance computing (HPC) systems are growing more powerful by utilizing more hardware components. As the system mean-time-before-failure correspondingly drops, applications must checkpoint more frequently to make progress. However, as the system memory sizes grow faster than the bandwidth to the parallel file system, the cost of checkpointing begins to dominate application run times. A potential solution to this problem is to use multi-level checkpointing, which employs multiple types of checkpoints with different costs and different levels of resiliency in a single run. The goal is to design light-weight checkpoints to handle the most common failure modes and rely on more expensive checkpoints for less common, but more severe failures. While this approach is theoretically promising, it has not been fully evaluated in a large-scale, production system context. To this end we have designed a system, called the Scalable Checkpoint/Restart (SCR) library, that writes checkpoints to storage on the compute nodes utilizing RAM, Flash, or disk, in addition to the parallel file system. We present the performance and reliability properties of SCR as well as a probabilistic Markov model that predicts its performance on current and future systems. We show that multi-level checkpointing improves efficiency on existing large-scale systems and that …

Navy Force Structure and Shipbuilding Plans: Background and Issues for Congress

This report provides background information and presents potential issues for Congress concerning the Navy's ship force-structure goals and shipbuilding plans. The planned size of the Navy, the rate of Navy ship procurement, and the prospective affordability of the Navy's shipbuilding plans have been matters of concern for the congressional defense committees for the past several years. Decisions that Congress makes on Navy shipbuilding programs can substantially affect Navy capabilities and funding requirements, and the U.S. shipbuilding industrial base.

Formalism for Neutron Cross Section Covariances in the Resonance Region Using Kernel Approximation (open access)

Formalism for Neutron Cross Section Covariances in the Resonance Region Using Kernel Approximation

We describe analytical formalism for estimating neutron radiative capture and elastic scattering cross section covariances in the resolved resonance region. We use capture and scattering kernels as the starting point and show how to get average cross sections in broader energy bins, derive analytical expressions for cross section sensitivities, and deduce cross section covariances from the resonance parameter uncertainties in the recently published Atlas of Neutron Resonances. The formalism elucidates the role of resonance parameter correlations which become important if several strong resonances are located in one energy group. Importance of potential scattering uncertainty as well as correlation between potential scattering and resonance scattering is also examined. Practical application of the formalism is illustrated on {sup 55}Mn(n,{gamma}) and {sup 55}Mn(n,el).
