Project: Applying Computationally Efficient Schemes for BioGeochemical Cycles (ACES4BGC)
The Applying Computationally Efficient Schemes for BioGeochemical Cycles (ACES4BGC) project will advance the predictive capabilities of Earth System Models (ESMs) by reducing two of the largest sources of uncertainty, aerosols and biospheric feedbacks, to deliver a second-generation ESM with improved representation of biogeochemical interactions at the canopy-to-atomsphere, river-to-coastal ocean, and ocean-to-atmosphere interfaces. Significant computational challenges emerge from the scientific requirement to support large numbers of reactive biogeochemical tracers across ESM component models. In particular, a new computationally efficient, accurate, and conservative tracer advection scheme is critically needed. Moreover, routine monitoring and performance optimization are required to assure project success.
