Tag name: ctsm1.0.dev102

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.]

46+
[x] clm5_0

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

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
