Precursor projects

CISL’s Advanced Research Computing Division announced that Derecho will be delayed until June 2022. This could provide lead time to pursue precursor projects (on a different platform such as KAUST’s Shaheen II) to test various aspects of the experimental setup such as adaptive inflation and the influence of certain observations such as sea surface salinity.

Adaptive inflation

An experiment contrasting the behavior of the inverse-gamma adaptive inflation algorithm of Gharamti (2019) in eddy-parameterizing and eddy-resolving ocean models has not been attempted. Such an experiment would enable the team to test the ASD experimental configuration over short (model week to month) integration periods.

Sea surface salinity

Deppenmeier et al. (2021) studied the temperature structure of the Pacific Cold Tongue (PCT). The PCT is adjacent to the Eastern Tropical Pacific Fresh Pool, yet the influence of salinity on the structure of the PCT is poorly understood. A/B experiments, in which sea surface salinity is assimilated and not assimilated could be conducted to gauge its influence on the predicability of the PCT.
