CODE’s new ultra-rapid orbit and ERP products for the IGS     

Simon?LutzEmail author  Gerhard?Beutler  Stefan?Schaer  Rolf?Dach  Adrian?J?ggi 《GPS Solutions》2016,20(2):239-250

The International GNSS Service (IGS) issues four sets of so-called ultra-rapid products per day, which are based on the contributions of the IGS Analysis Centers. The traditional (“old”) ultra-rapid orbit and earth rotation parameters (ERP) solution of the Center for Orbit Determination in Europe (CODE) was based on the output of three consecutive 3-day long-arc rapid solutions. Information from the IERS Bulletin A was required to generate the predicted part of the old CODE ultra-rapid product. The current (“new”) product, activated in November 2013, is based on the output of exactly one multi-day solution. A priori information from the IERS Bulletin A is no longer required for generating and predicting the orbits and ERPs. This article discusses the transition from the old to the new CODE ultra-rapid orbit and ERP products and the associated improvement in reliability and performance. All solutions used in this article were generated with the development version of the Bernese GNSS Software. The package was slightly extended to meet the needs of the new CODE ultra-rapid generation.  相似文献

On the kinematics of zircon growth and its petrogenetic significance: a cathodoluminescence study   总被引：26，自引：0，他引：26  

Gerhard Vavra 《Contributions to Mineralogy and Petrology》1990,106(1):90-99

The relative growth rates of zircon crystal faces are recorded by growth zoning, which is recognizable in cathodoluminescence photographs of oriented crystal sections. The kinematics of zircon growth is graphically presented by the slopes of Grabahnen between crystal sectors. The relative velocities of advance of crystal faces correlate to the pattern of growth zoning. Widely spaced zoning, interrupted by surfaces of dissolution, on the one hand, and narrowly spaced uninterrupted oscillatory zoning, on the other hand, are interpreted as markers of low and high zircon-supersaturation of the melt, respectively. The following model is deduced from this correlation. The prism {110} is that crystal form, the growth rate of which reacts most sensitively to the zircon-supersaturation of the melt. The growthrate of the steep pyramid {211} is not primarily controlled by zircon-supersaturation. Instead, the growth of {211} is delayed by the adsorption of foreign atoms on its faces. The kinematics of zircon growth in anatectic, plutonic and meta-rhyolitic host rocks in the pre-Mesozoic basement of the Tauern Window (Eastern Alps) is explained by this model. Results show that the kinematics of zircon growth carry a much greater petrogenetic significance than has been previously suggested for the final shape of crystals alone.  相似文献

Über Temperaturanomalien an der Meeresoberfläche und ihre Beziehungen zur atmosphärischen Zirkulation     

Gerhard Neumann 《Ocean Dynamics》1950,3(3-4):206-213

Zusammenfassung An Hand von Beobachtungen über periodische und unperiodische Temperaturschwankungen im Nordatlantischen Ozean wird versucht, die Frage Anomalietransport oder lokale Anomaliebildung zu klären, bzw. festzustellen, welche von beiden Entstehungsursachen für die auftretenden Schwankungen die wichtigere ist. Die Frage wird zu Gunsten der lokalen Anomaliebildung entschieden. Die Temperaturschwankungen treten in groen Gebieten des Atlantischen Ozeans fast gleichzeitig auf und verschwinden ebenso. Sie zeigen eine auffallende Gegensätzlichkeit im nordwestlichen und südöstlichen bzw. östlichen Teil des Nordatlantik, so da von einer nordatlantischen Wärmeschaukel gesprochen werden kann. Das Erscheinen der Anomalien hat dynamische Gründe und steht im Zusammenhang mit Schwankungen der ozeanischen Zirkulation, die dem Meere durch Schwankungen der atmosphärischen Zirkulation aufgeprägt werden.

On temperature anomalies at the sea surface and their relation to atmospheric circulation

Summary Based on observations on periodic and aperiodic temperature oscillations in the North Atlantic an attempt is made to discover whether these oscillations are due to wandering or locally generated anomalies, or which of these two phenomena is predominant. The problem is settled in favour of local generation of anomalies. Oscillations of temperature appear and vanish almost simultaneously in wide regions of the Atlantic. In their occurrence there is a striking contrast between the north western and the south eastern or eastern parts of the North Atlantic — one may speak of a North Atlantic temperature see saw. The anomalies are of dynamic origin and are connected with oscillations of the oceanic circulation which are impressed on the sea surface by oscillations of the atmospheric circulation.
