“…Secondly, CDIAC AmeriFlux data products are being published into the Earth System Grid Federation (ESGF). ESGF is a data distribution portal used primarily to distribute large-scale, modeling results (Williams et al, 2009). ESGF integrates supercomputers with petabyte-scale data and analysis servers located at national laboratories and research centers to create a powerful environment for next generation climate research.…”

Abstract. The Carbon Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory (ORNL), USA has provided scientific data management support for the US Department of Energy and international climate change science since 1982. Among the many data archived and available from CDIAC are collections from long-term measurement projects. One current example is the AmeriFlux measurement network. AmeriFlux provides continuous measurements from forests, grasslands, wetlands, and croplands in North, Central, and South America and offers important insight about carbon cycling in terrestrial ecosystems. To successfully manage AmeriFlux data and support climate change research, CDIAC has designed flexible data systems using proven technologies and standards blended with new, evolving technologies and standards. The AmeriFlux data system, comprised primarily of a relational database, a PHPbased data interface and a FTP server, offers a broad suite of AmeriFlux data. The data interface allows users to query the AmeriFlux collection in a variety of ways and then subset, visualize and download the data. From the perspective of data stewardship, on the other hand, this system is designed for CDIAC to easily control database content, automate data movement, track data provenance, manage metadata content, and handle frequent additions and corrections. CDIAC and researchers in the flux community developed data submission guidelines to enhance the AmeriFlux data collection, enable automated data processing, and promote standardization across regional networks. Both continuous flux and meteorological data and irregular biological data collected at AmeriFlux sites are carefully scrutinized by CDIAC using established quality-control algorithms before the data are ingested into the AmeriFlux data system. Other tasks at CDIAC include reformatting and standardizing the diverse and heterogeneous datasets received from individual sites into a uniform and consistent network database, generating high-level derived products to meet the current demands from a broad user group, and developing new products in anticipation of future needs. In this paper, we share our approaches to meet the challenges of standardizing, archiving and delivering quality, well-documented AmeriFlux data worldwide to benefit others with similar challenges of handling diverse climate change data, to further heighten awareness and use of an outstanding ecological data resource, and to highlight expanded software engineering applications being used for climate change measurement data.

“…The model simulations therein require adherence to a strict experimental protocol and also to a strict protocol for the format of the model output fields to facilitate ease of use by the climate analysis community Doutriaux 2010, Taylor et al 2011). The distribution of these fields is to occur, in general, by the Earth System Grid (ESG), an initiative led by PCMDI 1 , which features a global distribution system involving interconnected nodes located in many nations engaged in climate system research (Williams et al 2009). Analyses using the fields contributed to the ESG for CMIP5 will form the basis of the modelling contribution to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5), due for publication during 2013 and 2014.…”

There are two versions of global coupled climate models developed at the Centre for Australian Weather and Climate Research (CAWCR) participating in phase 5 of the Coupled Model Inter-comparison Project (CMIP5), namely ACCESS1.0 and AC-CESS1.3. This paper describes the CMIP5 experimental configuration of the AC-CESS models and the climate forcings for the historical and future scenario runs.We also present an initial analysis of model results, concentrating on changes in surface air temperature and the hydrologic cycle, and on climate sensitivity. Both models somewhat underestimate the observed 20th century warming, particularly in mid century, though recent warming rates match those observed. Mean warming for 2081-2100 relative to 1986-2005 under the RCP8.5 scenario is 3.61 K and 3.56 K for ACCESS1.0 and ACCESS1.3 respectively, and under RCP4.5 it is 2.34 K and 2.12 K.Climate sensitivity from idealised simulations is 10-15 per cent larger in AC-CESS1.0 than ACCESS1.3 and both models are above the median of the range of CMIP3 and published CMIP5 results.

Abstract. Experiences with three practical meteorological applications with different characteristics are used to highlight the core computer science aspects and applicability of distributed computing to meteorology. Through presenting cloud and grid computing this paper shows use case scenarios fitting a wide range of meteorological applications from operational to research studies. The paper concludes that distributed computing complements and extends existing high performance computing concepts and allows for simple, powerful and cost-effective access to computing capacity.
