    An OGC Web Processing Service for assessing the quality of solar radiation measurements
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Espinar, Bella; Gschwind, Benoit; Wald, Lucien; Thomas, Claire
    A service is presented that assesses the quality of measurements of daily global irradiation or means of global irradiance acquired by a ground station. Measurements are checked against models resulting in a measure of plausibility. This on-line service obeys the WPS (Web Processing Service) standard of the Open Geospatial Consortium. It is free of use and can be integrated into routine operations and Web portals thanks due its interoperability capability.

    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.
