ACCESS-NRI support of high-resolution modelling using ACCESS-RM with ERA5 driving conditions
Abstract
Researchers working outside of operational centres, such as the Australian Bureau of Meteorology, that wish to work on high-resolution modelling have different barriers to entry and ability to access data.
High-resolution ACCESS model runs require initial- and lateral boundary conditions. Instead of using initial- and lateral boundary conditions from the parent (ACCESS) model, researchers outside of operational centres tend to use initial- and lateral boundary conditions from reanalysis datasets such as ERA5 or ERA5-land.
There were known issues when using ERA5 soil moistures as an initial condition.
ACCESS-NRI has worked to:
• Circumvent the known issues when using ERA5 soil moistures as an initial condition.
• Add the ability to instead use ERA5-land land/surface (including soil moisture) information at 10km rather than 31km, or BARRA-R2 land/surface (also including soil moisture) at 11km NOT 31km.
• demonstrate the impact of using a double- rather than single-level nesting strategy.
The results of the ACCESS-NRI work will be shown in this talk along with the strategy to release suites that support similar work for interested researchers.
