  • Working: Robin to chase up with NCI for a non-access.admin tester account.
  • Working: Jin Lee has requested Rosebud as part of Rose; Ian to check if Rosebud is working with all UM versions (8.3-8.6) and install as standard accessdev utility.
  • Working: Handover of Ian's duties to Robin, Asri, Martin, Peter Uhe and Wenming; Robin to look at the handover strategy and details;

2. Rose-Cylc training and documentation

  • Working: Testing the migration from accesscollab to accessdev; Martin will add a link to Scott's wiki for testing users.
  • Working: so far the response to standard experiments does not meet the expectation; more work needs to be done to get more feedback
  • Working: NIWA Hilary Oliver's visit to BOM approved. The visit focuses on the training of using Cylc and consulting of the operational usage of Cylc at BNOC
  • Working: Consider moving access_wiki from to accesssdev. Scott following this up with NCI, has written script for NCI to do for this move.
    Ben thinks it is not a good idea; Ben/Scott and others may need to discuss this further

3. Rose-Cylc suite design

  • Working: Asri/Ilia working on rose-stem. Ilia working on including GCOM build as part of UM build, to tighten control over GCOM versions in UM; has some problems: FCM does not look for the specified GCOM lib.
    Action: Martin to do a simple GCOM test
  • Working: Pre-build libraries; ~access/prebuilds/um/vn9.x will be default place for um prebuilds, as per Asri's recommendation.

  • Working: Ian to complete N512 forecast suite. Some references to scripts in Xiao's directories to be moved to within suite. Peter S mentioned that radiation/aerosol fix from APS1 needs to be included in APS2.
