Define cheatgrass biomass to area relationship #458

Closed menglandjohns closed 4 years ago

menglandjohns commented 4 years ago

We need to define a working relationship between biomass of cheatgrass and the area/percent cover to connect fire probability relationships documented in literature with the biomass values needed for the model. Here are the findings documented so far:

@menglandjohns We need to scale cheatgrass biomass (g/m2) from STEPWAT2 to % cover (so we can apply the cheatgrass % cover-fire probability relationship you have derived in issue #324). From your previous work/documentation, you established:

1% cover of cheatgrass in a m2 = 10.296g of cheatgrass in a m2

That relationship comes from the following document: Cheatgrass threshold documentation.v2.docx

Correct me if I am wrong, but we should be able to check on the cheatgrass biomass within a given year in STEPWAT2 and convert that to % cover by dividing by 10.296g.

menglandjohns commented 4 years ago

@kpalmqui Yes, that sounds correct to me.

chaukap commented 4 years ago

@kpalmqui @menglandjohns I am going to create a function in ST_mortality.c to calculate cheatgrass percent cover. That way, we can modify it as needed.

kpalmqui commented 4 years ago

The code that converts biomass to percent cover is working as expected. I used printf statements to examine cover and biomass. As such, I am closing this issue.
