Surface Biology & Geology Pathfinder Data Analysis Pipeline

NASA's future global orbital mission, currently in development as the Surface Biology and Geology (SBG) Designated Observable study, will acquire relatively high resolution solar-reflected spectroscopy and thermal infrared observations. Innovative processes must be utilized for handling the high volume of data anticipated to be collected, which is anticipated to exceed 100 terabytes/day, greater than NASA's total extant airborne hyperspectral data collection. Collecting, processing/re-processing, disseminating, and exploiting this volume of data presents new challenges. To begin addressing them, NASA is drawing upon the expertise developed from its astrophysics programs to address Earth science and applications. Specifically, NASA is adapting the science processing operations technology developed for the Kepler and TESS planet-hunting missions for imaging spectroscopy data processing. This technology development has been the foundation for the remarkable scientific successes of Kepler and TESS. The Kepler/TESS data processing technology provides a scalable architecture for robust, repeatable, and replicable science and application products while enabling the Earth science community to develop, test, and implement new algorithms. Our effort to leverage this existing capability has begun by ingesting data and applying workflows from the EO-1/Hyperion 17-year mission archive that provides globally sampled visible through shortwave infrared spectra that are representative of SBG data types and volumes. This pathfinding data processing system will help define the solutions to processing SBG data volumes and will enable the scientific community to interact with the data and processing pipeline to create new science products

Elusive Complexity : New Data from late Halaf Domuztepe in South Central Turkey

Domuztepe is located in south central Turkey between the modern cities of Kahramanmaraş and Gaziantep. At about 20 ha, Domuztepe is one of the largest known settlements of the sixth millennium ВС date. Work has concentrated on the Late Halaf (Late Neolithic) layers within approximately 2 m of the surface. C14 dates suggest a time range for these strata of between ca. 5 700 and ca. 5 450 ВС (calibrated). The results discussed include evidence of widespread artificial terracing ; the excavation of an archaeologically elaborate mass burial ; and, in the top-most layers, an extensive architectural plan comprised of both rectilinear and round structures. The archaeological evidence for the ritual activities that accompanied the fractional burial of 35-40 individuals is presented in detail. Ceramic, glyptic and worked stone assemblages are described, and a brief overview of the paleoeconomy outlined. The paper concludes with a discussion of the evidence for emerging social complexity at the site.Domuztepe est situé au sud de la partie centrale de la Turquie entre les villes de Kahramanmaraş et Gaziantep. D 'une superficie d 'environ 20 hectares, Domuztepe est l 'un des plus grands établissements du 6e millénaire connu à ce jour. Les recherches ont porté sur les niveaux Halaf récent (Néolithique récent) qui se trouvent approximativement à 2 m de la surface et que les dates C14 permettent de dater entre ca. 5 700 et 5 450 ВС (cal.). Les résultats présentés ici concernent le large terrassement artificiel observé, la, fouille d 'un complexe élaboré de sépultures collectives ; et, pour les couches les plus récentes, le dégagement de structures architecturales les unes rondes, les autres rectililignes. Nous présentons en détail ce qui peut être mis en relation avec les rites qui auraient accompagné l'enterrement de 35-40 individus. Les ensembles céramique, glyptique et de pierre sont brièvement décrits et un aperçu de la paléo-économie est donné. En conclusion une discussion est proposée sur ce qui peut, sur ce site, suggérer l'émergence d'une certaine complexité de l'organisation sociale.Carter Elizabeth, Campbell Stuart, Gauld Suellen.

Workshop on Statistical Approaches for the Evaluation of Complex Computer Models

As decision- and policy-makers come to rely increasingly on estimates and simulations produced b y computerized models of the world, in areas as diverse and climate prediction, transportation planning, economic policy and civil engineering, the need for objective evaluation of the accuracy and utility of such models likewise becomes more urgent. This article summarizes a two-day workshop that took place in Santa Fe, New Mexico in December 1999, whose focus was the evaluation of complex computer models. Approximately half of the workshop was taken up with formal presentation of four computer models by their creators, each paired with an initial assessment by a statistician. These prepared papers are presented, in shortened form, in Section 3 of this paper. The remainder of the workshop was devoted to introductory and summary contents, short contributed descriptions of related models, and a great deal of floor discussion, which was recorded by assigned rapporteurs. These are presented in Sections 2 and 4 in the paper. In the introductory and concluding sections we attempt to summarize the progress made by the workshop and suggest next steps
