Understanding the Earth's climate system and how it might be changing is a preeminent scientific challenge. Global models are used to simulate past, present, future climates, experiments executed continuously on an array of distributed supercomputers. The resulting data archive, spread over several sites, currently contains upwards 100 TB simulation growing rapidly. Looking toward mid-decade beyond, we must anticipate prepare for research holdings many petabytes. Earth System Grid (ESG)...
The Athena science payload on the Mars Exploration Rovers (MER) includes Microscopic Imager (MI). MI is a fixed‐focus camera mounted end of an extendable instrument arm, Instrument Deployment Device (IDD). was designed to acquire images at spatial resolution 30 microns/pixel over broad spectral range (400–700 nm). uses same electronics design as other MER cameras but has optics that yield field view 31 × mm across 1024 pixel CCD image. acquires using only solar or skylight illumination...
By leveraging current technologies to manage distributed climate data in a unified virtual environment, the Earth System Grid (ESG) project is promoting sharing between international research centers and diverse users. In transforming these into collaborative community resource, ESG changing way global conducted. Since ESG's production beginnings 2004, its most notable accomplishment was efficiently store distribute simulation of some 20 coupled ocean-atmosphere models scores scientific...
This paper describes the first optical spectroscopic survey of Class I sources (also known as embedded and protostars) in Taurus-Auriga dark cloud. We detect 10 24 cloud at 5500–9000 Å. All detected have strong Hα emission; most also [O I] [S II] emission. These data—together with high-quality spectra T Tauri stars cloud—demonstrate that forbidden emission lines are stronger more common than stars. Our results provide a clear discriminant frequency line between weak-emission classical In...
Neutral sodium emissions encircling Jupiter exhibit an intricate and variable structure that is well matched by a simple loss process from Io's atmosphere. These observations imply fast neutral created locally in the Io plasma torus, both near as much 8 hours downstream. Sodium-bearing molecules may be present upper atmosphere, where they are ionized torus swept The molecular ions dissociate dissociatively recombine on short time scale, releasing fragments into escape trajectories Jupiter....
In the emerging world of Grid Computing, shared computational, data, other distributed resources are becoming available to enable scientific advancement through collaborative research and collaboratories. This paper describes increasing role ontologies in context Computing for obtaining, comparing analyzing data. We present ontology entities a declarative model that provide outline an information. Relationships between concepts also given. The implementation some described this is discussed...
In the last 30 years, earth system modeling has become increasingly data-intensive. The Community Earth System Model (CESM) response to next Intergovernmental Panel on Climate Change (IPCC) assessment report (AR6) may require close 1 Billion CPU hours of computation and generate up 12 PB raw data for post-processing. Existing post-processing tools are serial-only impossibly slow with this much data. To improve performance, our team adopted a strategy targeted replacement "bottleneck...
The international climate community is expected to generate hundreds of petabytes simulation data within the next five seven years. This must be accessed and analyzed by thousands analysts worldwide in order provide accurate timely estimates likely impact change on physical, biological, human systems. Climate thus not only a scientific challenge first but also major technological challenge. In address this challenge, Earth System Grid Center for Enabling Technologies (ESG-CET) has been...
With support from the U.S. Department of Energy's Scientific Discover Through Advanced Computing (SciDAC) program, we have developed and deployed Earth System Grid (ESG) to make climate simulation data easily accessible global modelling analysis community. ESG currently has 2500 registered users manages 160 TB in archives distributed around nation. From this past year alone, more than 200 scientific journal articles been published analyses delivered by ESG.
The recent release of the Intergovernmental Panel on Climate Change (IPCC) 4th Assessment Report (AR4) has generated significant media attention. Much been said about US role in this report, which included support from Department Energy through Scientific Discovery Advanced Computing (SciDAC) and other (DOE) programs for climate model development production execution simulations. SciDAC-supported Earth System Grid Center Enabling Technologies (ESG-CET) also played a major IPCC AR4: all...
The Jet Propulsion Laboratory's Field Integrated Development and Operations rover (FIDO) emulates tests operational capabilities for advanced Mars missions, such as those originally planned the Surveyor 2001 Rover currently Athena Payload on Exploration Rovers scheduled launch in 2003. This paper describes FIDO's science instrument payload, which is fully integrated with hardware software. Remote teams visualize suite data generate FIDO commands using Web Interface Telescience. has been used...
The Open Source Physics (OSP) project is a synergy of curriculum development, computational physics, computer science, and physics education for scientists students wishing to author interactive computer-based curricular material. This article illustrates how the OSP combines physical data XML tags (data metadata, respectively) with Launcher authoring tool give users an easy-to-use consistent paradigm creating, modifying, distributing Java-based material

Earth science high-performance applications often require extensive analysis of their output in order to complete the scien- tific goals or produce a visual image animation. Often this cannot be done situ because it requires calculating time-series statistics from state sampled over entire length run analyzing relationship between similar time series previous simulations observations. Many tools used for postprocessing are not themselves high- performance applications, but new Parallel...
