  • OLCF: none planned

PR board status

Latest issues and discussions

  • Q10 maint resp for c4 grasses
    • We are moving away from Ryan (to Atkin), so is this a "wont-fix" issue?
      • Both Ryan and Atkin don't have values for c4 baserate, so both suffer from a similar lack of data.
      • Consensus is that we should convert this to a discussion and continue there.
  • Email discussion: pan-amazon fates hydro errors in nocomp and SP configurations
    • Chongang looking into a possible solution to the dry failure cases that Jenny is seeing in a forthcoming PR. He will point Jenny to the old PR.

Calibration progress update

  • Jessie: allometry updates degrade ILAMB scores. Pattern is similar, just worse.
    • That said, this is constrained by data, so plan is to move forward calibrating with this.
    • Incorporating fire improved biomass, but did not impact LAI, likely due to there not being any understory.

Calibration progress update

  • Adrianna: Tuning Kumarathunge?
    • Charlie: Prefer to use paper's parameter which are tuned to observations.
      • Charlie/Rosie: How conditional on their own pft vcmax numbers are the other non-acclimation parameters provided in the paper (Table 2)
        • Check in with Alistair on this; Rosie to take action.
    • Marcos: from ED2, it was important to have C4 vcmax25top lower than C3 grasses to avoid GPP spiking.

Walk-on Topics

  • Adrianna: working on boreal fire
    • Bulk density seems low for boreal. Moss isn't present, which is a major contribution.
      • Additionally, perhaps we want to have different classes of leaf litter (needle versus broad)?
  • Marcos: testing drought-deciduous phenology (particularly timing)
    • Run SP + ST3? Idea is to have some initial forest inventory from SP, but keep it static via ST3
    • Ryan: alternate running ST3, but manually turn on phenology, but bypass some checks

  • New

Latest issues and discussions

Calibration progress update

  • Adrianna: Incorporated crop -> grass mapping. GPP is higher now (both in global total and map structure).

    • e3sm testing PR: Greg and Ryan discussed expanded test lists on e3sm side for fates
      • Greg and Ryan will run the expanded 'fates' list for API updates
      • Actions: ask e3sm land folks how many tests we can add to e3sm_land_developer suite
        • Note that this will increase the number of fates tests that run nightly and as such will increase our 'exposure' to maintaining these tests as e3sm does not really allow "expected failures".
  • New
    • LUH2 data tool "year" fix (1112): Ryan has approved.
      • This should have automated unit testing to make sure to avoid issues like this in the future
    • Landuse V2 (1116): this is still a WIP technically. One edge case to still handle.
    • User history density option (1119)
      • The namelist controls not just the output, but the allocation as well
      • Will have graceful failure for when user request including an output that conflicts with the level requested

    • Notice: Greg added upcoming API plan to the User's Guide HLM table
      • Developers can use this to see what the integration plan is a little more cleanly than the PR board.
    • Het resp fix (1114): Reviewed and approved. CTSM-side API update testing complete. E3SM-side testing underway.
      • Issue is that the bc_out%ema_npp was not getting updated in time for the hi frequency output as the model restart and the fates update of ema_npp was not in sync (due to ema_npp update only happening daily).
      • Note this is being rolled into E3SM-side seed dispersal PR.
  • New

Latest issues and discussions

  • None to discuss

Calibration progress update

  • Jessie: tried pulling in Rosie's crop updates (PR 817), two-stream, and Medlyn parameters. Got a bunch of failures that she's working on fixing before comfortable with the runs.
    • Rosie believes she was using Ball-Berry and not Medlyn. Adrianna running default Medlyn parameters?
      • Adrianna: not using default. Using Charlie's recommended from another reference. Also saw same crashes that Jessie is seeing.
        • Discussion of low GPP in Adrianna's recent results.
    • Note: changes in landuse v2 reformulates the no-comp initialization logic

Two-stream update

  • Jenny triggered an error: check on solver results.
    • One particular pft was causing the issue
    • Ryan looked into LAPACK to understand what could be causing the issue (i.e. what is acceptable precision for matrix inversion?)
      • Issue turned out to be if two differencing terms (beam and diffusion) in eq 26 of Ryan's manuscript is near zero, values become huge. Ryan to introduce check and small perturbation to avoid this state.

Walk-on Topics

  • Adrianna: fire model refactoring discussion. Proposing creating a patch fuel data class.
    • Would take in litter and other states and calculate/store fuel fraction, bulk density, etc.
    • Has unit tests and functional tests :D!
    • Consensus is yes.

    • Two stream: Marcos and Adrianna providing reviews.
      • Aside: Rosie noted that Mariana is looking to do some performance testing of fates. Rosie suggested she waited until this one was integrated.
        • Ryan wants to create a PR (HLM-side) to add namelist variable to tailor the set of history variable "classes" (i.e. site versus muliplexed). This would avoid calling the subroutines that populate the particular history variables.
    • tree pfts update (1093): Jessie reviewed the impact of fates_allom_blca_expnt_diff. Including this, which adjusts LAI wrt size, improves ILAMB results. Let move this in.
  • New
    • clean inventory init: removes extra columns and adds ed2 to fates python tool
      • Put c_height back in.
        • Aside: Marcos noted that dbh -> height isn't perfectly reversible
      • Consensus is that we should just remove the ED2 compatible format instead of keeping both FATES-only and ED compatible.
      • We should try running this globally to get a sense of the common assumption that this is going to be very slow.

Latest issues and discussions

Calibration progress update (Adrianna, Jessica, Rosie)

  • Adrianna: submitted min/max one-at-a-time run. Some of them crashed. Investigating.

Walk-on Topics

  • Rosie: spectral element grids. Does anyone know if CLM run on different grids.
  • Adrianna: LAI difference
    • Charlie: bigleaf and fates have differences in where they are being run for antarctic, greenland, and some other minor area. FATES is nan in the ice sheets.
  • Charlie: fates_max_nocomppft_landuse_vector discussion: we need to manage that we may have more pfts than we have patches available for a given landuse type. This new parameter would allow user to control this.
    • We define a maximum number of patches by landuse type. The new parameter would tell fates how many of the top pfts to prioritize to meet this limit.

      • Ryan: should we notify the community?
      • Aside: Rosie suggested that we add an agenda item once a monthly to pull together items for our "fates digest" monthly email. This would be a good candidate for this.
        • This was a previous discussion that we had regarding how to update fates users of software updates
    • LUH2 v1 (1040): reverted back to original terminate_patches method
    • cross-grid seed (1005): API-side test changes need update per CTSM#2151

Latest issues and discussions

Calibration progress update (Adrianna, Jessica, Rosie)

  • Adrianna: struggling with getting sparse grid to work with NUOPC. Sam Levis helping out.
    • Ryan to apply two-stream to another branch to help Adrianna to move forward around the NUOPC issue.

Walk-on Topics

  • Rosie: Low LAI in tropics discussion. What are our next steps from here (assuming GPP and carbon use efficiency is in the ballpark)
    • Jessie/Rosie: Why doesn't increasing root longevity improve this?
    • Charlie: should we try decoupling root/leaf optimization (in trimming)?

      • Erik: does FATES plan on holding multiple parameter files aside from the default on main?
        • Consensus seems to be our goal of building param files on the fly would cover regional or run-mode specific variations of the param files

  • Jessie: has a boreal forest that looks good now. Currently has a run spinning up that has good ILAMB results so far. Can share results next week.
    • How do we decide what species are representative of a particular pft?
      • Looking at extra tropical trees, it suggests we may want more pfts (e.g. late-succesional deciduous, early-succesional deciduous).
      • As first pass, update since this is an improvement (provinence-wise and results-wise)
        • Potential future work: Weighting by abundance or iding species that are representative for the given pft?

E3SM restart issues (Jessie)

  • E3SM commit 0777e39115 on April 11th onwards introduces EAMXX. From that point onwards Jessie was finding restarts were not working.
    • Removing ./xmlchange DOUT_S=TRUE (short term archiving enabled) from script solved the restart issue

FATES paleo (Adrianna)

  • Sophia Macarewich running CLM-FATES Amazon single site runs in three different scenarios including 1850, last glacial maximum and paleo
  • Greg suggested this might be good for a future FATES modeling meeting topic. Adrianna suggests maybe November. She is providing support to Sophia.

    • 999 (CLM BGC compatibility)
      • Ryan would like to assess impact of reordering of root fraction calculations on the elm-fates results.
        • This would ideally be before the elm-side luh2 and seed dispersal pull requests (but after the refactor).

  • Updated

    • E3SM#5849 (refactor) tested and waiting on e3sm approval/integration
      • Greg to check in with Gautum and Peter S.
    • 1055 (too much canopy): added final regression testing forthcoming
    • 1040 (LUH2): updated patch insertion and fusion procedures
      • Fusion routine updated to fuse very small patches into largest patch of different landuse type if not possible to merge into same type
        • Need to assess if landuse transition rates could create small patches below threshold

  • Next tags

    • Given BGC-reorder check and refactor merge on e3sm side, move forward with seed dispersal and landuse on ctsm side.
      • Find reviewers for #1040. Retest seed dispersal and move this ahead of landuse in the ctsm queue.

Latest issues and discussions

Calibration progress update (Adrianna, Jessica, Rosie)

  • Adrianna: Ryan to call into calibration meeting this week, to talk about getting 2-stream ready for PPE.
  • Adrianna: Sparse grid for dominant pfts. What threshold should we use for "dominant?"

Walk-on Topics

  • Greg to create an issue for assessment of sp mode area tolerances
    • Rosie noted that the genesis for this was due to needing canopy to fully fill error (or we see downstread rad errors).
      • Perhaps "canopy shyness" gap mechanism would help with rad error? Ryan agrees that 2-stream will help enable this if desired.

  • Adrianna: CLM5 PPE
    • fff has large impact on FATES GPP
    • Working on getting relative % change in parameter affect (as opposed to absolute change)
    • Charlie: looking at spatial distribution would be interesting. He suspects it'll be split between snow/no snow areas
    • Next steps:
      • Bring in Ryan's two-stream branch to see the affect on the albedo bias
      • Another PPE with just fates params and then maybe clm + fates
      • Latin hyper-cube set (on for albedo tuning and then decision on next calibration steps)
    • Charlie: What about elm/clm param divergence? Maybe to investigate: calibration of fates with just fates versus fates + hlm params?

Walk-on Topics

  • Jessie: ELM-FATES training next summer
    • Geared towards ForestGeo community and potentially run at their sites. Inventory init since no met data available.
    • Still need to talk with Stuart to see if we're going to hold it concurrently with existing planned ForestGeo workshop or be standalone.

CTSM PR expectations and NCAR resource allocation

  • PR expectations discussion
    • Rewording 2a so as to not suggest precluding turn FATES on by default
    • 2b example is hillslope-hydrology
    • Ryan noted that we should add a refactor/code cleanup/bug fixes/performance improvement item (1c?)
      • (Marcos) 1a concerns about correcting bug or improving model to better align with data but making something else worse
      • (Will) Agreed. Example LUNA fixes degraded the performance, but were necessary
  • Resource allocation discussion
    • Dedicated FATES resources at NCAR: Jackie and Adrianna
    • How to handle concern of where to focus development (big-leaf versus fates)
    • CESM3 and FATES
      • Ideally there would be CESM FATES runs for TRENDY and CMIP
        • LULCC is limiting factor -> resource allocation
