This new issue of the Mercator Ocean newsletter is dedicated to the Pre-operational PREVIMER system (see article 1, this issue for a general introduction to the Previmer system) which provides coastal observations and forecasts along French coasts: currents, waves, sea levels, temperature, salinity, primary production and turbidity. Previmer marine environment data come from in situ observations, satellite images, and numerical models.
They are centralized and archived in Center for Data in Coastal Operational Oceanography, then published on website and finally disseminated to users.
The present issue describes in details all the components of the PREVIMER users system.
The Previmer project was launched on 2006 to enlarge the French operational oceanography capability towards the coastal areas. The first phase (2006-2007) focused on various demonstrators (sea states, coastal circulation, primary production and water quality). The second phase (2008-2013) has ended last December 2013 and aimed at building infrastructures and tools in order to ensure an operational service for the benefit of a wide community (private companies, public organisms, defense, and citizens).
The four main components that constituted the Previmer project are:
- in situ observations: instrumental development, data acquisition, deployment and exploitation of optimized instrumental networks to produce specific coastal data. This component is illustrated in the 3 following papers by Charria et al., Beurret and Thomas as well as Beurret et al.
- modeling tools: development and evolution of numerical models, coupling of hydrodynamical (waves and circulation), sedimentological, biogeochemical models, data assimilation, tools for the chemical and toxicity risk analysis. This component is illustrated with 7 papers: see for example the papers in this issue by Pineau-Guillou et al, Ardhuin et al. and Garnier et al.
- interface tools for users and advanced products: satellite data processing, synthetic indicators, data, images, dissemination thanks to the web. This component is illustrated in this issue in the 2 following papers: Theetten et al. and Raynaud et al.
- data center dedicated to coastal operational oceanography (CDOCO): acquisition, quality control, diffusion of observations and model results, implementation of the models and data center, daily production of services and products. This component is illustrated in the following paper: Faillot et al., this issue.
