make land use change and nocomp work together #15
Comments
Notes to self on how to handle this (copied from email I just wrote): We need the various files at https://gdex.ucar.edu/dataset/188b_oleson/file.html such as Basically the prescribed landcover version in the absence of land use change currently uses the PFT map from the surface dataset file, which I believe is a regridded version of So for FATES non-crop PFTs, what we would want to do for a nocomp configuration with land use change is read in a regridded version of the forest/pasture/other PFT maps directly, which would put into the same file that we are currently putting the luh2 data into. And then for each gridcell, we would assign a PFT x land-use matrix that defines the nocomp PFT weighting for each land use type in that gridcell. So primary and secondary lands would both be the forest/nonforest-weighted average of the Once we have that matrix, then FATES would initialize the nocomp PFTs based on the weighting matrix and the land use types for a given year, and then would update the nocomp patch areas to reflect the changing land use weightings over time as driven by the transition matrix. |
things to do still:

One way this might work is to change the use_fates_logging from a boolean flag to an integer flag with the following values:

note that this was not the first read/write of restarts, it was the second one (after 2 successful 3-month iterations) EDIT ran into this again in a different run:
second edit: I believe that commit 401bdd8 might fix this, but I don't fully understand the nature of the problem and so want to confirm that that is the best solution. |

Branch started here off of Landuse V1 e3sm PR: https://github.com/glemieux/E3SM/tree/lnd/fates-luh2-harvest |
HI @glemieux in addition to |
sorry, I created a new branch that merges the harvest + v2 landuse together to be the new 'official' code called For background see: glemieux/E3SM#30 (comment) |
