Global land cover is a key variable in the earth system with feedbacks on climate, biodiversity and natural resources. However, global land cover data sets presently fall short of user needs in provid...
This work is an extended evaluation of near-surface ozone as part of the global reanalysis of atmospheric composition, produced within the European-funded project MACC (Monitoring Atmospheric Composit...
We present "Met.3D", a new open-source tool for the interactive three-dimensional (3-D) visualization of numerical ensemble weather predictions. The tool has been developed to support weather forecast...
We present the application of interactive three-dimensional (3-D) visualization of ensemble weather predictions to forecasting warm conveyor belt situations during aircraft-based atmospheric research ...
We describe and test a two-horizontal-dimension subglacial hydrology model which combines till with a distributed system of water-filled, linked cavities which open through sliding and close t...
We present the first stage of a new online-coupled global to regional-scale modeling framework for the simulation of the spatiotemporal evolution of aerosols and trace gases. The underlying me...
This study presents an extended vertical grid for the regional atmospheric model COSMO (COnsortium for Small-scale MOdeling) reaching up to 33 km. The extended setup has been used to stably simulat...
We evaluate the ISBACC (Interaction Soil Biosphere Atmosphere Carbon Cycle) land surface model (LSM) over the Amazon forest, and propose a revised parameterization of photosynthesis, including new so...
Karst develops through the dissolution of carbonate rock and is a major source of groundwater contributing up to half of the total drinking water supply in some European countries.ate rock and is a ...
The NetCDF (Network Common Data Form) library has become an indispensable tool for data and model output management in geoscience. However for simple tasks, particularly in Fortran, the complexity o...
This is nominally a review of a 2001 publication, the NOAA Diving Manual, Diving for Science and Technology, 4th edition, NTIS Order Number PB99-144321INQ, and available from NTIS, see www.ntis.gov/pr...
Ebb and Flow: Tides and Life on Our Once and Future Planet is well titled. It tells the story of tides, why they matter, what causes them, and how they have changed over time. The author, Tom Koppel, ...

The one hundredth anniversary of Robert Peary's controversial North Pole claim was in April 2009, and the centennial of Roald Amundsen's undisputed dash to the South Pole is coming up in December 2011...
2200年初等几何一直认定相互平行且距离为0的直线必重合相等,等长的直线段必有合同关系;然而集合与几何起码常识凸显直线A沿本身伸缩或平移后就≠A了,有等长直线段a与b,a的元点多于b的元点使a不可≌b——从一侧面显示2200年“点无大小”公理并非“不容置疑”(坚持“点无大小”就无法解释图形a与b的“像素”点为何不一样多?)。人类自识无理数2500年来一直认定各已知正数x的对应x/2均是已知正数,然...
依据岩心、常规薄片及铸体薄片、物性分析、压汞等资料的研究,四川盆地中部下寒武统龙王庙组滩相储层为发育良好的中低孔、低渗的孔隙型储层及裂缝—孔隙型储层。储集岩主要为砂屑白云岩、鲕粒白云岩与具残余颗粒结构的粉—细晶白云岩,储集空间主要包括粒间溶孔、粒内溶孔、晶间溶孔、铸模孔、残余粒间孔、裂缝及溶洞,孔喉配置关系好。储层形成机制研究表明,滩核和滩翼微相有利于储层发育,滩相储层在沉积早期具有典型的宏观非均...
