| 5 | +One-line Summary: Some important fixes for LUNA in clm5_0, and small urban issue in clm5_0 |
| 6 | + |
| 7 | +Purpose of changes |
| 8 | +------------------ |
| 9 | + |
| 10 | +Fix some important issues that were found in LUNA for the arctic. These changes were large enough |
| 11 | +that we had to re-tune the clm5_0 parameters to give a similar simulation. Leah Birch noticed |
| 12 | +that the formulations in the code disagreed with the paper. Correcting this caused arctic plants |
| 13 | +to be less productive. In order to compensate parameters for leafcn, and slatop were adjusted for |
| 14 | +broadleaf_deciduous_boreal_shrub and c3_arctic_grass for clm5_0. |
| 15 | + |
| 16 | +The total vegetation carbon threshold on exit_spinup (from accelerated decomposition (AD) mode) was |
| 17 | +increased from 0.1 to 1.0. Without this change some PFT's can die out in exit spinup even when |
| 18 | +they have significant carbon stores from the AD spinup mode. |
| 19 | + |
| 20 | +There is an implicit assumption in the urban building energy model that building width equals |
| 21 | +street width. However, this assumption can/should be relaxed and building width can be derived |
| 22 | +from the morphology dataset. |
| 23 | + |
| 24 | + |
| 25 | +Bugs fixed or introduced |
| 26 | +------------------------ |
| 27 | + |
| 28 | +Issues fixed (include CTSM Issue #): #738 #803 #953 #958 #1056 |
| 29 | + Fixes #1056 -- Remove allpfts dimension |
| 30 | + Fixes #953 -- Incorrect formula in LUNA uses day time rather than average of day/night |
| 31 | + Fixes #958 -- LUNA day length factor missing |
| 32 | + Fixes #738 -- Totvegc threshold increased from 0.1 to 1. |
| 33 | + Fixes #803 -- No longer assume building width |
| 34 | + |
| 35 | +Known bugs introduced in this tag (include github issue ID): #1060 |
| 36 | + #1060 -- Some code cleanup of luna bug fixes |
| 37 | + |
| 38 | +Significant changes to scientifically-supported configurations |
| 39 | +-------------------------------------------------------------- |
| 40 | + |
| 41 | +Does this tag change answers significantly for any of the following physics configurations? |
| 42 | +(Details of any changes will be given in the "Answer changes" section below.) |
| 43 | + |
| 44 | + [Put an [X] in the box for any configuration with significant answer changes.] |
| 45 | + |
| 46 | +[x] clm5_0 |
| 47 | + |
| 48 | +[x] ctsm5_0-nwp |
| 49 | + |
| 50 | +[ ] clm4_5 |
| 51 | + |
| 52 | +Notes of particular relevance for users |
| 53 | +--------------------------------------- |
| 54 | + |
| 55 | +Caveats for users (e.g., need to interpolate initial conditions): clm5_0 climate adjusted for arctic plants |
| 56 | + |
| 57 | +Changes to CTSM's user interface (e.g., new/renamed XML or namelist variables): none |
| 58 | + |
| 59 | +Changes made to namelist defaults (e.g., changed parameter values): |
| 60 | + |
| 61 | +Changes to the datasets (e.g., parameter, surface or initial files): New parameter files |
| 62 | + |
| 63 | +Substantial timing or memory changes: None |
| 64 | + |
| 65 | +Notes of particular relevance for developers: (including Code reviews and testing) |
| 66 | +--------------------------------------------- |
| 67 | +NOTE: Be sure to review the steps in README.CHECKLIST.master_tags as well as the coding style in the Developers Guide |
| 68 | + |
| 69 | +Caveats for developers (e.g., code that is duplicated that requires double maintenance): We |
| 70 | + chose some bad names for variables, so we'll clean this up in a seperate step (see #1060) |
| 71 | + |
| 72 | +Changes to tests or testing: None |
| 73 | + |
| 74 | +Code reviewed by: self, olyson, bill-sacks, wweider |
| 75 | + |
| 76 | + |
| 77 | +CTSM testing: regular |
| 78 | + |
| 79 | + [PASS means all tests PASS and OK means tests PASS other than expected fails.] |
| 80 | + |
| 81 | + build-namelist tests: |
| 82 | + |
| 83 | + cheyenne - PASS (266 compare differently because of update in paramsfile and jmaxb1) |
| 84 | + |
| 85 | + python testing (see instructions in python/README.md; document testing done): |
| 86 | + |
| 87 | + cheyenne - PASS |
| 88 | + |
| 89 | + regular tests (aux_clm): |
| 90 | + |
| 91 | + cheyenne ---- PASS |
| 92 | + izumi ------- PASS |
| 93 | + |
| 94 | +If the tag used for baseline comparisons was NOT the previous tag, note that here: |
| 95 | + |
| 96 | + |
| 97 | +Answer changes |
| 98 | +-------------- |
| 99 | + |
| 100 | +Changes answers relative to baseline: Yes for clm5_0 |
| 101 | + |
| 102 | + If a tag changes answers relative to baseline comparison the |
| 103 | + following should be filled in (otherwise remove this section): |
| 104 | + |
| 105 | + Summarize any changes to answers, i.e., |
| 106 | + - what code configurations: clm5_0 when Luna on as well as smaller changes for urban |
| 107 | + - what platforms/compilers: all |
| 108 | + - nature of change: climate changing, but tuned to respond similar to clm5.0 |
| 109 | + |
| 110 | + If this tag changes climate describe the run(s) done to evaluate the new |
| 111 | + climate (put details of the simulations in the experiment database) |
| 112 | + luna changes: oleson case clm50_ctsm10d089_2deg_GSWP3V1_luna3_jmaxb1-0.17_slatopA_leafcnA_hist |
