Low relative humidity discontinuity discussion

  • Discovered via Demo of Leaf Biophys Unit Tests
    • Are the discontinuities due to singularities in stomatal conductance calculation?
    • Marcos has seen this in ED2 as well and addressed it.
      • Dynamically make sure that the initial guesses don't straddle the singularity.
  • Only an issue with Ball-Berry. Move to medlyn as the default?
    • Adrianna: Melyn has a correction that doesn't allow humidity to get that low (cap on VPDs between leaf and atm, not atm itself).
      • CLM apparently fixed the issue and removed the cap.
        • Ryan removed the caps for medyln and didn't see the issue reappear.
      • That said Adrianna is seeing convergence errors.
    • Ryan and Marcos to setup a meeting to discuss

Latest issues and discussions of note

  • Grass sapwood allometry hydro issue (#1254): Xiulin to create PR to address this soon.
  • Biomass outputs updating for non-new cohort only
    • Ryan: if its a state should be included, but if its a flux it shouldn't be used. We need to do an audit of Sam's list and what is/isn't a flux.
      • Marcos: Issue is more if its per plant rather than per area.
    • Future refactor: splitting history interface mode between fluxes and states
    • Immediate work: audit the list and create PR to correct. This should be based on Sam's PR and come in afterwards.
  • FATES simluation in desert environs: Rosie answered. Cross-post low relative humidity issue here as well.

Calibration progress update

  • Adrianna: getting results for co-dominant

Walk-on topics

  • Sam: distinction between subroutine hist dyn 1 and 2?
    • Adrianna: suggests renaming the subroutines to be more descriptive

  • Charlie: Seed rain impact on spin up discussion (wrt nocomp calibration)
    • Seeds may be supporting a population of plants that are constantly dying
    • Should we be making some metric/ecosystem benchmarks to make sure that certain pfts are being represented
      • It appears that die-off is mostly in grasses
      • Investigate using Xiulin's new grass allometry
      • Charlie to update with more detailed maps showing the differences

      • Adrianna current work doesn't include bl ever extra trop, and broad decid extra trop
        • Since so much is changing with sp mode calibration inputs (e.g. gswp3 -> cru), might as well update this and redo sp calibration
    • Jennifer: Drive to get this in is to meet NGEE-A milestone
    • Greg: start regression testing to get ahead of any other issues since API updates are coming up soon in queue
      • Greg to start e3sm API update

Initial feedback

  • Just under half responded via survey so far: mostly positive feedback, some constructive critism
  • Software: Docker setup pre-tutorial could use improvement; more introductory material on working in the terminal
  • Presentations: Slow down speech cadence during presentations and spend a little more time during intro talks
  • Balance of time between hands-on practice and presentations: slight bias towards more presentations with examples of use

FATES team feedback

  • Ryan: Presentations as breaking up the day
  • Jessie: more presentations on different processes in fates (guided examples)
  • Ryan: make it more clear that they can take breaks when they want

PR board status update

Updates

  • Fire Weather Refactor: Updates made and retested. Results as expected.
    • To be integrated next. No need to wait for CTSM API updates.
  • Arctic shrub PFT additions: Should this update the default or have a new cdl file? If not, how do we test this?
    • Making default cons: not tested pan-arcticly (one arctic site only), would complicated calibration efforts (?)
      • Adrianna: there have been multiple parameter file updates during calibration, so not that big of a concern for SP calibration work
      • Check in with Rosie about non-comp impact
    • Multiple parameter files? Consensus is no; either update default or just provide xml for this PR.
      • Testing with xml only option: we could test this using the parameter auto-gen workflow
      • TODO: run long global 4x5 smoke test. If results look good, make this default.
  • CTSM API 36.1 update: Waiting on higher priority ctsm-side PRs to meet CTSM5.3.0 tag

New

Latest issues and discussions of note

  • CanopyStructure third canopy layer
    • Added new clause is causing issues due to tolerance. Some version of check should be performed, but not sure what tolerance.
      • Ryan: imperfect plasticity would help this, but radiation scattering makes that difficult.
    • Charlie: leave open; needs more investigation.
  • EDPFTVarcon merging: Ryan will address this.
  • FATES inventory pft error: Greg to reach out to author to ask for files
  • Charlie's Restart Error: under investigation; Ryan reproduced error
    • Ryan: Not all of the params the drive 2-stream have reasonable values on the restart. Adding error codes to exit back into calling subroutine.

    • Sam to work on replicating Rosie's fire work (3 pfts)

Latest issues and discussions of note

  • 2-stream restart error: testing on main with Charlie's minimum script is passing
    • Charlie: Issue has to do with grazing. He's confirmed that removing grazing alleviates the issue he was seeing.
  • Charlie: canopy structure issue (to be )
    • There is a check missing that needs added to make sure that the canopy is full before adding to lower canopy layers
    • Immediate fix is to change order of promotion from lower to upper
    • Whats the reasonable tolerance level on check?
      • Rosie: check the largest error for crash
    • Prioritization of conservation values (dbh, mass, etc) resulting in conflicts
    • Marcos: ED2 doesn't conserve DBH and back-calculates. FATES is more complicated.

Calibration progress update

  • Adrianna: No major updates. Script for dominant and co-dominant grid working.
  • Greg: documentation of process and tools used? Maybe this should be a discussion point for the coordination meeting?

PR board status update

Use of fates synchronized branches with CTSM (not master)

  • Motivation: FATES development team can merge in PRs that are synchronized with CTSM on our own schedule, allows users to have a CTSM branch that is always compatible with FATES master
  • Questions:
    • Should we have a single branch (fates-latest)? Or a branch for each expected tag?
    • What frequency should we merge ctsm updates into this (these) branches?
      • Every ctsm tag/PR?
      • Only when the new branch is merged into ctsm master?
    • Should PRs be issued to fates-latest? Or ctsm's master?

Hydro / SP mode compatibility (Ryan)

  • Ryan noting that we need to add new features to make hydro and sp mode work together.
    • As such, we shouldn't consider failure in the mode to be a bug, but a feature not yet supported.
    • Greg to take the action to add graceful failure with both modes in API35 and API34 ctsm and e3sm PRs respectively.

Walk-on topics

Latest issues and discussions of note

Calibration progress update

  • Rosie: discussion of disconnect between tuning and diagnostics packages for land

Fire emission coupling hackathon (Rosie)

  • Goal: get fire emissions out of fates and into atmosphere model
  • Calculate biomass burned and pass to HLM to calculate emissions or fates calculate emissions directly
    • emissions are pft specific suggesting we should have fates calculate directly
      • would result in duplication of emissions factors from HLM
  • Charlie: is emission a function of fire "type" (i.e. anthro versus wildfire)
    • Rosie: yes, but pft is a proxy of this
  • Ryan: discussion or issue?

Hydaulic failure discussion (Chonggang)

  • Option: when leaf water potential high, zero stomatal conductance and not request water
    • May improve numerical stability
    • Chonggang hoping to attempt this at the end of the month
  • Ryan: preference is to implement linear model between
    • Alternate (short term?): run case at much shorter time steps to get through snags
  • Charlie: Develop dry condition test failures (e.g. single site at Atacama)
    • Ryan: functional unit testing
      • satphen + hydro?
    • Greg: being able to parameterize functional unit tests would be great

    • Considering adoption of Adrianna's ML method for next iteration (post SP-mode calibration updates)
    • Ryan: stem respiration for calibration?
      • Jessie: Not currently. Kolby keen to investigate this for next project phase. Discussions about field-to-model integration details on going.

Tutorial update

  • Jennifer: what's the accessibility goal? Will we explain how to setup the container, etc?
    • Jessie: Ultimate goal is to make this available all online with a very simple BCI method.
      • Greg: We also have a tutorial setup guide repo in development to host a readthedocs style walkthrough of setting up on a laptop.
    • Greg: OLMT experience? We might use or compare the single site subsetting function for pre-processing.
      • Jennifer: Yes, two years ago. Current attempts to use were hampered however.
      • Ryan: Running pre-process all at once?
        • Jessie: yes, we could use the sparse grid NCL method.

Latest issues and discussions of note

FATES speed audit update (Ryan)

  • Can we avoid leaf layer loop: Trimming routine forces us to iterate over leaf layer depth
  • Current plan: investigate Ci iteration cap and threshold. Update as necessary along with remembering the previous value.
  • Initial iteration analysis update suggests that we often hit the iteration cap.
    • Initial iteration testing with ST3 mode (audit was using full dynamics however).
  • ED2 experience: What about trying Newton method using the derivitives from reduced analytical form? Review the ED2 approach and share with team.
  • Investigate impact of making photosynthesis loosely coupled?

Calibration progress update

  • Adrianna: CLM surface data does not seem to quite match ILAMB observation. This is causing issues with gridcell to gridcell comparison.
    • Ask Nate Collier for help.
  • Calibration team to review Adrianna's brute-force method and will review selected parameter ranges.

PR board status update

Latest issues and discussions of note

  • LU data tool fails on derecho: probably taking too much memory for login node. This will need to be addressed eventually for CLM LU build on the fly.
    • This came up in the context of checking ctsm python environment on derecho, due to a dependency issue for xesmf.
    • Erik/Charlie: test this on the develop queue

Calibration progress update

  • Adrianna: Ran Ball-Berry without temp acclimation. Observational mean is more easily achieved, but emulator does a worse job.
    • Temperture acclimation without very low vcmax
      • Charlie: Claire Zarackas is finding something similar in the absence of hydraulics. So there is a scientific rationale for excluding temp acclimation.
  • Jessie: met with Ryan to talk about carbon budget issue; add recruitment carbon flux. Carbon budget closes now.
    • Not sure if recruitments that die in the same timestep are showing up in the diagnostics

Walk-on topics

  • Rosie: Question: Matvey fates model focus? Take over Marius work? Where does it fall in the priority?
    • Jennifer: arctic-fire stuff coming up prior to arctic-hydro. Maybe hardening?
    • Greg: This is back on API 17, so bringing it up before it gets too stale would be good
    • Charlie/Ryan/Rosie: recent hydro issues do suggest that addressing hardening is a good idea.
    • Matvey: only calibrated to 2 local sites; will it work globally?

Building parameter files on the fly

  • Ryan to look at moving this forward this week

Latest issues and discussions of note

  • hydro dry region failure: Marcos has been working with Jenny on this. Recommendation is that she not trace the issue since its out of scope for her work.
    • Ryan proposing to add a fail safe for extreme outlier cases to allow fates run to complete. Still need to make sure this is actually an outlier.

Calibration progress update

  • Calibration branch
    • Jessie still needs this branch until 2-stream gets to E3SM (probably a few weeks at this point). The calibration branch is pretty close to FATES main for her purposes, so no need to merge main into calibration branch.

Walk-on topics

  • Erik asking about status of Marius' frost branch
