Some changes of the work plan build process (w/r to the MoU4 practices) were introduced in 2017 in the framework of the newly signed ALADIN-HIRLAM cooperation agreement, the strategy meeting held in Toulouse and the 2nd joint ALADIN General Assembly and HIRLAM Council.
The Directors approved the definition of these three types of activities :

  • Part 1. common activities (activities necessary to create the export versions) : code delivery, maintenance and support activities;
  • Part 2. core programs (R&D): commonly agreed programs of recognized strategic importance that will benefit all partners. Two core programs are proposed “Scalability” (numerics, scalability and HPC developments) and “DA for ALL partners” (Development of a DA “starters kit” to help those ALADIN Members who do not have an operational data assimilation yet, and further developments of 3Dvar).
  • Part 3. specific activities : all activities carried out outside of the core programs that
    • a.) are needed by a limited group of member states who invest resources in it, OR
    • b.) do not lead in the short term to the creation of a new CMC or a major extension of the sanity check, OR
    • c.) are not needed to guarantee operations; a first list of specific activities has been identified during the strategy meeting.

The Rolling Work Plan (RWP) is reorganized accordingly, with commitments from all Partners to the core programs. The impact on the code design/code implementation of the science is made more visible and the new RWP aims to allow for a better planning and reporting in the future, with focus on deliverables. It also helps identify code contributions, thus defining the ALADIN-HIRLAM common codes.

During the HMG/CSSI meeting in Helsinki, it was agreed that :

  • Part 1 & 2 are left to the responsibility of the ALADIN and HIRLAM PMs and should be written before the end of the summer;
  • Part 3 is organised in Work Packages (WPs), following the “best practice” of H2020.
    • Each WP has an editorial leadership, with a WP redactor (WPR) who is responsible for the redaction of the relevant part of the RWP and the coordination of the redaction, but not for its realisation. The WPRs should contact people in the consortia to make sure that they cover the topic of the WP.

Annual calendar for establishing the RWP :

  • The list of WPs and their leader redactors (WPRs) is set up and agreed on during the HMG/CSSI meeting every year and presented to HAC/PAC.
  • The WPRs propose to the 3 PMs a concise draft of their WPs, using the new template.
  • The 3 PMs (ALADIN, HIRLAM, LACE) integrate the components of the RWP.
  • The Local Team Managers (LTM) for ALADIN are presented with the RWP besides the EWGLAM meeting (1st week of October) and commit the manpower.
  • HAC review the RWP at their meeting late October. It will be proposed to the PAC to move their annual meeting from spring to autumn, when they could comment on the proposed RWP, at a joint meeting with HAC.
  • The joint GA/Council (end of year) is presented with the RWP, including deliverables and manpower commitments.
