The work plan reflects the willingness to co-design and co-develop the projects, and associates the three categories of partners (academics, ski resorts, solution suppliers). The project is organized in six work packages. This deliberately small number of work packages is intended to maintain strong ties between project partners along a focused path culminating at the achievement of the project results. The key nodal point of the co-design approach relies on the establishment throughout the entire project of cross-cutting local working groups (LWG), one for each participating ski resort. Each LWG will comprise at least one representative from the resort technical management team, a technical and science partner and all stakeholders directly concerned with the use of data. The LWG will be involved in all resort-level activities, in particular in WP1, WP2 and WP4.

WP1 (Set-up, computation and provision of meteorological and snowpack forecasts) will assess the existing tools and databases for snow and snow cover anticipation: historical snowfall and snow cover datasets, remotely-sensed snow observations, prediction systems from one week to several months ahead and their skill for snow and other parameters, snow models and their compatibility with seasonal forecast systems. It will develop and implement the data processing tools upstream individual locations handled by the demonstrator and set-up the relevant data-stream. It will evaluate the physical components used by the demonstrator based on long-term observation sites in different European countries. It will quantify the uncertainties and propose visualizations deemed manageable by the ski resorts and mountain professionals.

WP2 (Climate services market, co-design and value in the European ski industry) will improve our knowledge of the demand and of the other economical, legal and institutional conditions for market deployment, at resort, national and Alpine levels.
Work tasks will include user need assessment involving all the LWG, and an extended sample of ski resort managers, assessment of existing meteorological and climate services, development of communication channels of climate services from national or European services to final users, and establishment of public/private partnerships and institutional arrangements. The legal framework of existing and yet-to-develop products will be assessed specifically.

WP3 (Demonstrator specification and implementation) will provide the technical specifications of demonstrator, and implement them (web services, APIs, server architecture, web access, newsletter, weekly brief, breaking news on climate forecasts).
It will then interact at all steps with WP4 to continuously improve the demonstrator, during and post implementation. It will finally deliver a final version integrating users’ feedback.

WP4 (Pilot deployment, exploitation and evaluation) will exploit in real time the PROSNOW Demonstrator at the pilot ski resorts (through the involvement of all LWG), thereby demonstrating the PROSNOW proof-of-concept, providing feedback necessary to improve the Demonstrator, and contributing to evaluating its added value and potential for market replication.

WP5 (Dissemination and preparation for market exploitation), based on the project outputs, will disseminate the results and prepare market exploitation…. Industrial partners will be mobilized as multiplier factors, to consider complementarities with their offers and to reach end-users. The final objective is to establish a structure in charge of exploiting PROSNOW products in the long-run.

WP6 (Scientific coordination, project management and communication) will be in charge of project management, coordination of scientific activities, and coordination of communication activities.
