• Common architecture (ALL)• Orographic downscaling (WC)• Variably saturated flow - VSF (WC)• PFLOTRAN BGC interface (BGC)• Coupled C-N-P cycles (BGC)• Alternative plant-microbe competition - ECA (BGC)• Initial crop model improvements (ALL)• MOSART river routing - uncoupled (ALL)• UQ framework (ALL)• Evaluation / benchmarking framework (ALL)• Functional unit testing framework (ALL)
Capabilities in development for V2• VIC-based runoff• MOSART river routing – coupled• Managed hydrology• Riverine biogeochemistry• Improved soil thermal hydrology – PFLOTRAN• Improved root hydrology• Explicit microbes, methane model• Nitrification, denitrification, N-fixation• Ecosystem demography – ED• Additional UQ• Additional evaluation / benchmarking• Human dimensions (pending)
Progress to date on V1 developments (1 of 2)
• Common architecture– Decision made to base ED development on V1 model, eliminating
long-lived ED development branch
• Orographic downscaling– Documented approach, developing subgrid elevation, coordinating
with atmosphere group
• Variably saturated flow (soil hydrology)– PETSc-based solver complete, coupled to surface fluxes
• PFLOTRAN BGC interface– BGC interface complete and tested for C-N coupling
• Coupled C-N-P model– C-N-P development complete, site-level testing underway

Progress to date on V1 developments (2 of 2)• Alternative plant-microbe competition – ECA
– Three papers submitted describing new approach for nutrient competition, plant traits, and advective losses
• Crop model improvements– Dynamic rooting profiles, harvest routine port complete
• MOSART river routing – uncoupled– Inundation model tested for Columbia and Amazon river basins
• UQ framework– Sensitivity analysis for two sites with ACME V0 (55 parameters,
10,000 simulations), paper in review– Spinup acceleration and offline model acceleration achieved
• Benchmarking framework– Group development of data sets and metrics continues
• Functional unit testing– Code analysis for ACME v0

Progress to date on V2 developments (1 of 2)
• Water management– Global testing ongoing
• Riverine BGC– Sediment model added to MOSART, simple global
parameterization– MOSART migration to ACME code base is underway
• Improved thermal hydrology – PFLOTRAN– Migrated interface to ACME code (complete)– Initial global tests in 1D (vertical-only) mode complete, above-
freezing
• Improved root hydrology– Dual continuum connected matrix approach implemented,
benchmark case for macropore flow developed and executed

Progress to date on V2 developments (2 of 2)
• Microbe-enabled decomposition and methane dynamics– Development and testing in new BGC framework underway
• Nitrification, denitrification, N-fixation– Developing and analyzing reduced order models
• Ecosystem Demography – ED– Vegetation demography, size-structured plant competition,
mechanistic mortality, and plant trait filtering introduced in ACME, based on CLM-ED
– Site-level evaluation underway for Manaus Brazil, Iquitos Peru, the Congo, and a temperate forest in California
• Human dimensions (pending)– Prognostic human influence on carbon and water cycles
