Description
E3SM v1.1 updates the model's land, ocean, sea ice, and coupled biogeochemistry configurations, and will be used for the E3SMv1 biogeochemistry science campaign.
This release includes scientifically-validated tunings of the E3SM Land Model (ELM) and E3SM Atmosphere Model (EAM) for coupled simulations with active land biogeochemistry, for ELM configurations using both the CTC and ECA approaches to representation of nutrient competition. Spun-up initial conditions will be made available later.
Additional diagnostic variables have been made available as history variables from the ELM, and from the MPAS-Ocean and MPAS-Seaice biogeochemistry modules, in order to improve consistency with the output variable requests of the Coupled Climate Carbon Cycle Model Intercomparison Project (C4MIP), and to support improved analysis of the land, ocean, and sea ice carbon cycles.
The atmosphere models prognostic CO2 code has been updated to enable regridding of anthropogenic CO2 emission files to the E3SMs native spectral element grid. Note that (1) the prognostic CO2 configuration of E3SM has not been scientifically validated, and (2) the regridding of emission files as currently implemented is not mass-conserving and is intended as a temporary workaround. We do not advise using E3SMv1.1 for fully-coupled carbon cycle simulations where mass conservation is critical, but it is suitable for enabling use of the 3D CO2 tracer for diagnostic and testing purposes.
Several bugs found after v1.0 DECK runs started have been fixed. These include: adding limiters to avoid bad extrapolation in RRTMG, CLM surface water and lake fixes, fixes an error in the calculation of NIR reflectance that affects cloud fields derived from MODIS simulator As a result, this version can not reproduce BFB v1.0 simulations results.
In addition, a number of minor bugfixes and technical improvements have been introduced in the EAM, ELM and MPAS-Ocean models.
