Coupling GCAM to E3SM Tim Shippert, PNNL tim.shippert@pnnl.gov 3/19/2019
Development Overview Coupler modifications to add IAC component integrated assessment component Single letter z Status: Coded, in testing, debugging unit tests on ANVIL l->z coupling modifications to CLM and GCAM CLM: NPP and HR to coupler GCAM: read from coupler Status: designed, coding in progress
Development Overview (cont) z->l coupling modifications to CLM and GCAM GCAM: send land use data to coupler CLM: replace surfdat file with read from coupler Status: designed, coding in progress z->a coupling modifications to CAM and GCAM GCAM: CO2 flux to coupler CAM: CO2 flux from GCAM added to CLM flux Status: in development
Additional tasks Create and run compsets with GCAM coupling Generate unit tests Documentation for adding a new component Merge with up-to-date E3SM version Update to GCAM 5 currently using GCAM 3 Additional couplings, some code restructuring (submodule)
