Kulawik, Susan S.; Worden, John; Eldering, Annmarie; Bowman, Kevin; Gunson, Michael; Osterman, Gregory B.; Zhang, Lin; Clough, Shepard A.; Shephard, Mark W.; Beer, Reinhard, 2006, "Implementation of cloud retrievals for Tropospheric Emission Spectrometer (TES) atmospheric retrievals : part 1. description and characterization of errors on trace gas retrievals", https://hdl.handle.net/2014/40387, Journal Of Geophysical Research, Vol. 111, D24204, doi:10.1029/2005JD006733, 2006, JPL Open Repository
We develop an approach to estimate and characterize trace gas retrievals in the presence of clouds in high spectral measurements of upwelling radiance in the infrared spectral region (650–2260 cm-1). The radiance contribution of clouds is parameterized in terms of a set of freque... |

Froidevaux, L.; Livesey, N. J.; Read, W. G.; Salawitch, R. J.; Waters, J. W.; Drouin, B.; MacKenzie, I. A.; Pumphrey, H. C.; Bernath, P.; Boone, C.; Nassar, R.; Montzka, S.; Elkins, J.; Cunnold, D.; Waugh, D., 2006, "Temporal decrease in upper atmospheric chlorine", https://hdl.handle.net/2014/40388, Geophysical Research Letters, Vol. 33, L23812, doi:10.1029/2006GL027600, 2006, JPL Open Repository
We report a steady decrease in the upper stratospheric and lower mesospheric abundances of hydrogen chloride (HCl) from August 2004 through January 2006, as measured by the Microwave Limb Sounder (MLS) aboard the Aura satellite. For 60°S to 60°N zonal means, the average yearly ch... |

Erosion rates derived from the Gusev cratered plains and the erosion of weak sulfates by saltating sand at Meridiani Planum are so slow that they argue that the present dry and desiccating environment has persisted since the Early Hesperian. In contrast, sedimentary rocks at Meri... |

Temma, T.; Baines, K. H.; Butler, R. A. H.; Brown, L. R.; Sagui, L.; Kleiner, I., 2006, "Exponential sum absorption coefficients of phosphine from 2750 to 3550 cmˉ¹ for application to radiative transfer analyses on Jupiter and Saturn", https://hdl.handle.net/2014/40229, Journal Of Geophysical Research, Vol. 111, E12003, doi:10.1029/2006JE002720, 2006, JPL Open Repository
PH exponential sum k coefficients were computed between 2750 and 3550 cmˉ¹ (2.82–3.64 µm), in view of future application to radiative transfer analyses of Jupiter and Saturn in a phosphine absorption band near 3 µm. The temperature and pressure of this data set cover the ranges f... |

Space-based measurements of reflected sunlight in the near-infrared (NIR) region promise to yield accurate and precise observations of the global distribution of atmospheric CO2. The Orbiting Carbon Observatory (OCO) is a future NASA mission, which will use this technique to meas... |

We have recently completed a prototype ion-clock physics package based on Hg ions shuttled between a quadrupole and a 16-pole rf trap. With this architecture we have demonstrated short-term stability ~2-3x10-13 at 1 second, averaging to 10-15 at 1 day. This development shows that... |
