[Biogenics] Expanding Emissions for More Flexibility Across Chemical Mechanisms #89

Open drnimbusrain opened 10 months ago

drnimbusrain commented 10 months ago

As discussed at today's UFS-CATChem development meeting, there may be need to expand the current capabilities of canopy-app biogenics to have more granularity and flexibility across chemical complexity and more PFT complexity.

As a first step, we could follow MEGANv3 for mapping across chemical complexity. Currently, MEGANv3 takes the 19 compound class output species, speciates to 201 species, and then remaps to any chemical mechanism complexity using set mechanism input files (e.g., CB06, SAPRC, RADM, etc.). Currently on GMU Hopper, the MGN2MECH codes are found by example at:

_/groups/ESS/pcampbe8/MEGAN/MEGANv3.2_Dec2021/src/MGN2MECH/mgn2mech.F

This would be relatively easy to make an option in canopy-app to follow the MEGANv3 mapping and output the chemical mechanism/complexity is desired.

@quaz115 I would like to add Maggie in the future to work on this as well.

After talking with Jeff Willison (EPA) at CMAS, he noted that MEGANv3 had major bug in its chemical mapper mechanism, and to ensure we follow latest code updates (since at least Dec 2022 release). https://bai.ess.uci.edu/megan/data-and-code/megan32
