• TR “mono”

  • oRRS18to6 → ne256pg2

    • takes about 7h to produce (single processor)

    • Weights are good. Row sums are bad (1.2e-6) Column sum error 1.1e-6

    • Status: usable for development. NOT USABLE FOR PRODUCTION

  • oRRS18to6 → ne1024pg2: too expensive/too much memory. need MBTR to compute in parallel.

• MBTR “mono”

  • oRRS18to6 → ne256pg2

  • Weights are good, but 316 MPAS grid points have weight=0. This is incorrect and corrupts other diagnostics.

  • Status: NOT USABLE

• ESMF “aave”

  • oRRS18to6 → ne256pg2

    • weights are good. row sum error 1e-11. Conservation error 1.5e-11

    • Status: GOOD

  • oRRS18to6 → ne512pg2

    • weights are good. row sum error 1e-11. conservation error 1e-11

    • Status: GOOD

  • oRRS18to6 → ne1024pg2

    • weights are bad: max 2.6

    • issue: ncks --chk_map row sum error 3e-11 ( so not seeing the 2.6 weight - it’s probably in a region with frac_a or frac_b << 1)

    • AnalyzeMap reports rowsum = 3 (consistent with 2.6 weight)

    • ncks --chk_map conservation error: 3.1e-11

    • AnalyzeMap:

    • Status: NOT USABLE
