Observations for CMIP5 Simulations

The objective of this is to provide the community of researchers that will access and evaluate the Coupled Model Intercomparison Project Phase 5 (CMIP5) model results access to analogous, analogous sets in terms of periods, variables, temporal/spatial frequency, sets of observational data. A collaborative effort between JPL/NASA and PCMDI is underway to provide the community of researchers that will access and evaluate the CMIP5 model results access to analogous sets of observational data. A number of NASA satellite data sets have been identified that have model equivalents. Thus far: AIRS, MLS, TES, QuikSCAT, CloudSat, Topex/Poseidon, CERES, TRMM, AMSR-E have been identified.

Geometric Comparisons of Selected Small Topographically Fresh Volcanoes in the Borealis and Elysium Planitia Volcanic Fields, Mars: Implications for Eruptive Styles

MOLA (Mars Orbiter Laser Altimeter) data from small, topographically fresh volcanoes from the Elysium and Borealis regions were gridded and analyzed using GMT (Generic Mapping Tools) programs. Results compare eruptive styles of the two regions, and draw conclusions about the different volcanic regions. Additional information is contained in the original extended abstract.

Small Shield Volcanoes on Mars: Global Geometric Properties and Model Implications for Regional Variations in Eruptive Styles

Small martian volcanic shields geometric parameters show a global latitude dependence. Modeling results and observations are best explained by a sensitivity to an increasing availability of subsurface volatiles towards the polar regions. Additional information is contained in the original extended abstract.

Gigaflop (billion floating point operations per second) performance for computational electromagnetics

Accurate and rapid evaluation of radar signature for alternative aircraft/store configurations would be of substantial benefit in the evolution of integrated designs that meet radar cross-section (RCS) requirements across the threat spectrum. Finite-volume time domain methods offer the possibility of modeling the whole aircraft, including penetrable regions and stores, at longer wavelengths on today's gigaflop supercomputers and at typical airborne radar wavelengths on the teraflop computers of tomorrow. A structured-grid finite-volume time domain computational fluid dynamics (CFD)-based RCS code has been developed at the Rockwell Science Center, and this code incorporates modeling techniques for general radar absorbing materials and structures. Using this work as a base, the goal of the CFD-based CEM effort is to define, implement and evaluate various code development issues suitable for rapid prototype signature prediction.

Detection of a magnetic region on HR 1099

The paper reports results of a magnetic field measuring campaign on the active K component of the RS CVn system HR 1099, using Zeeman-Doppler imaging. A localized magnetic field is detected near quadrature (phase 0.85). Assuming this magnetic region has a circular shape, its longitude and latitude are, respectively, estimated to be 86 + or - 4 deg and 5 + or - 5 deg. This equatorial region is largely monopolar, has a mean field strength of 985 + or - 270 G, covers 18 + or - 3 percent of the total stellar surface and may be colocalized with a bright photospheric spot.
