Wu, Dong L., 2004, "Mesoscale gravity wave variances from AMSU-A radiances", https://hdl.handle.net/2014/40861, Geophysical Research Letters, Vol. 31, L12114, doi:10.1029/2004GL019562, 2004, JPL Open Repository
A variance analysis technique is developed here to extract gravity wave (GW) induced temperature fluctuations from NOAA AMSU-A (Advanced Microwave Sounding Unit-A) radiance measurements. By carefully removing the instrument/measurement noise, the algorithm can produce reliable GW... |

Kahn, Ralph; Ku, Wen-Hao; Martonchik, John; Bruegge, Carol J; Diner, David J.; Gaitley, Barbara J.; Abdou, Wedad; Dubovik, Oleg; Holben, Brent; Smirnov, Alexander; Jin, Zhonghai; Clark, Dennis, 2004, "MISR Calibration and implications for low-light-level aerosol retrieval over dark water.", https://hdl.handle.net/2014/39257, Journal of the Atmospheric Sciences - Special Section, Vol. 62, 1032-1052., JPL Open Repository
The authors push the limits of the vicarious calibration method’s accuracy, aiming to assess absolute, camera-to-camera, and band-toband radiometry. Patterns repeated over many well-constrained cases lend confidence to the results, at a few percent accuracy, as do additional vica... |

Wilson, Eric H.; Atreya, S. K., 2004, "Current state of modeling the photochemistry of Titan’s mutually dependent atmosphere and ionosphere", https://hdl.handle.net/2014/40873, Journal of Geophysical Research, Vol. 109, E06002, doi:10.1029/2003JE002181, 2004, JPL Open Repository
In the context of recent observations, microphysical models, and laboratory data, a photochemical model of Titan’s atmosphere, including updated chemistry focusing on rate coefficients and cross sections measured under appropriate conditions, has been developed to increase unders... |

Aguirre, Arturo Hernandez; Zebulum, Ricardo S.; Coello, Carlos Coello, 2004, "Evolutionary multiobjective design targeting a field programmable transistor array", https://hdl.handle.net/2014/40941, 2004 NASA/DoD Conference on Evolvable Hardware (EH'04), http://doi.ieeecomputersociety.org/10.1109/EH.2004.1310831, JPL Open Repository
This paper introduces the ISPAES algorithm for circuit design targeting a Field Programmable Transistor Array (FPTA). The use of evolutionary algorithms is common in circuit design problems, where a single fitness function drives the evolution process. Frequently, the design prob... |

Treuhaft, Robert N.; Law, Beverly E.; Asner, Gregory P., 2004, "Forest attributes from radar interferometric structure and its fusion with optical remote sensing", https://hdl.handle.net/2014/40842, BioScience, Vol. 54 No. 6, June 2004, doi: 10.1641/0006-3568(2004)054, JPL Open Repository
The possibility of global, three-dimensional remote sensing of forest structure with interferometric synthetic aperture radar (InSAR) bears on important forest ecological processes, particularly the carbon cycle. InSAR supplements two-dimensional remote sensing with information i... |

Sekanina, Zdenek; Chodas, Paul W., 2004, "Fragmentation hierarchy of bright sungrazing comets and the birth and orbital evolution of the Kreutz system. I. Two-superfragment model", https://hdl.handle.net/2014/39288, The Astrophysical Journal, 607:620–639, 2004 May 20, DOI: 10.1086/383466, JPL Open Repository
A back-and-forth orbit integration technique, developed for our previous investigation of the splitting of the parent of the sungrazers C/1882 R1 and C/1965 S1, is now applied in an effort to understand the history and orbital evolution of the Kreutz sungrazer system, starting wi... |

Qiu, Yueming; Uhl, David, 2004, "Self-assembled InAsSb quantum dots on (001) InP substrates", https://hdl.handle.net/2014/40905, Applied Physics Letters, Volume 84, Number 9, 1 March 2004 DOI: 10.1063/1.1655690, JPL Open Repository
Self-assembled InAsSb quantum dots (QD) on (001) InP substrates have been grown using metalorganic vapor phase epitaxy. The dot density and size are found to be strongly dependent on the presence of arsine. Direct deposition of InSb on InP and GaSb substrates formed large islands... |
