Climate Model Development and Validation

archived

The Climate Model Development and Validation (CMDV) Activity in the Climate and Environmental Sciences Division (CESD), Office of Biological and Environmental Research (BER) of the Office of Science (SC), U.S. Department of Energy (DOE), is a new effort to improve climate model architecture, software, and computational design to prepare for exascale computing, to develop scale-aware physics for climate systems, and to enhance methods for model validation. This solicitation focuses mainly on the development and validation of scale-aware physics parameterizations for the atmosphere, with the goal of including these in either the current or next generation version of DOE’s Accelerated Climate Model for Energy (ACME). A recent workshop report (http://www.arm.gov/publications/programdocs/acme-arm-asr-draft-report.pdf) describes a new strategy to better align DOE capabilities across scales and disciplines in order to much more rapidly advance ACME development. In line with this strategy, this FOA solicits university and other non-DOE-Laboratory investigators to participate as collaborators in team projects led by DOE National Laboratories that will work in an end-to-end manner between measurements and modeling, and across scales from local and/or regional to global, in order to improve the fidelity of global climate model simulations, with a view to enhanced predictability and address critical climate science challenges. The model representation of clouds and aerosols, and their changes in response to energy and climate drivers, remain the most uncertain elements in model predictions of the climate system. Therefore, improved predictability requires greater understanding and representation of the behaviors of clouds and chemistry within global climate models.
