    Early achievements towards an automatic assessment of the uncertainty in solar irradiation using web services
    (Innovations in Sharing Environmental Observations and Information, 2011) Wald, Lucien; Blanc, Philippe; Espinar, Bella; Gschwind, Benoit; Lefevre, Mireille; Menard, Lionel; Wald, Fabien; Hoyer-Klick, Carsten; Schroedter-Homscheidt, Marion; Thomas, Claire
    A long standing effort aims at creating and operating an automatic procedure for the assessment of the uncertainty in solar radiation data and the delivery of this information to users. This communication presents the early achievements. The overall objective can be seen as composed of three specific objectives: 1) assessing the uncertainty of the satellite-derived irradiation compared to a reference; 2) as the uncertainty depends on atmospheric conditions, devising a model that can predict uncertainty at any location and any time; 3) delivering information to users. As irradiation data are already delivered through the SoDa Service and the IEA SHC#36 / MESOR portal, it is natural to use these dissemination media and to embed the uncertainty quantities in the data flow. The strategy is to implement the overall procedure by the means of interoperable Web services. Two ensembles of Web services are being developed: one for the assessment protocol, the other for the model of uncertainty.

    Human health impacts for Renewable Energy scenarios from the EnerGEO Platform of Integrated Assessment (PIA)
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Lefevre, Mireille; Gschwind, Benoit; Blanc, Isabelle; Ranchin, Thierry; Wyrwa, Artur; Drebszok, Kamila; Cofala, Janusz; Fuss, Sabine
    This article reports impact results from running the EnerGEO Platform of Integrated Assessment (PIA) related to human health for different scenarios in Europe. The scenarios were prepared within the EnerGEO project. The idea of this European project is to determine how low carbon scenarios, and in particular scenarios with a high share of renewable energy, affect concentrations of air pollutants and as a consequence affect human health. PM2.5 concentrations were estimated with the IIASA Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model on a time horizon up to the year 2050 for different scenarios. We analyse here the estimation of the Loss of Life Expectancy due to PM2.5 concentrations for the Baseline scenario taken as a reference and the Maximum renewable power scenario.

    SoDa: A Project for the Integration and Exploitation of Networked Solar Radiation Databases
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Wald, Lucien; Albuisson, Michel; Best, Clive; Delamare, Catherine; Dumortier, Dominique; Gaboardi, Elena; Hammer, Annette; Heinemann, Detlev; Kift, Richard; Kunz, Stefan; Lefevre, Mireille; Leroy, Sebastien; Martionli, Mario; Menard, Lionel; Page, John; Prager, Tamas; Ratto, Corrado; Reise, Christian; Remund, Jan; Rimoczi-Paal, Aniko; Van der Goot, Erik
    The project SoDa (solar data) answers the needs of industry and research for information on solar radiation parameters with a satisfactory quality. The methodology is user-driven with a large involvement of users in the project, who gauge the progresses and achievements. A prototype service has been developed, using Internet technology, that integrates and efficiently exploits diverse networked information sources to supply value-added information. Access to data and applications has been greatly improved; efforts were made on interpolation methods and satellite data processing to achieve better quality and increase time and space coverage of the information. Applications were developed or networked to supply information actually needed by customers, and not only raw data.

    The EnerGEO Platform of Integrated Assessment (PIA): environmental assessment of scenarios as a web service
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Blanc, Isabelle; Gschwind, Benoit; Lefevre, Mireille; Beloin-Saint-Pierre, Didier; Ranchin, Thierry; Ménard, Lionel; Cofala, Janusz; Fuss, Sabine; Wyrwa, Artur; Drebszok, Kamila; Schaap, Martijn
    With the International Energy Agency estimating that global energy demand will increase between 40 and 50 percent by 2030 (compared to 2003), scientists and policymakers are concerned about the sustainability of the current energy system and what environmental pressures might result from the development of future energy systems. EnerGEO is an ongoing FP7 Project (2009-2013) which assesses the current and future impact of energy use on the environment by linking environmental observation systems with the processes involved in exploiting energy resources. The idea of this European project is to determine how low carbon scenarios, and in particular scenarios with a high share of renewable electricity, affect emissions of air pollutants and greenhouse gases (GHG) and contribute to mitigation of negative energy system impacts on human health and ecosystems. A Platform of Integrated Assessment (PIA) has been elaborated to provide impact results for a selection of scenarios via a set of models (large-scale energy models, Life Cycle Assessment models, ...). This PIA is currently available through a web service. The concept of the PIA is detailed and to illustrate its interest, a set of results is given with the use of the simulation mode of the European version of GAINS for a selection of scenarios.
