Configuration for the pre-operational MONAN global 10km uniform resolution

[saulorfreitas]

Pull Request Description

Describe what this Pull Request contains and the changes made.

This develop contains further configuration for the pre-operational MONAN global 10km uniform resolution to run in the new CRAY supercomputer. It contains new tunning for the GF scheme and also defaults to WSM6 as the cloud microphysics parameterization to be applied. In this case, the 'namelist.atmosphere' present in the directory 'namelist_monan' must be used. It should requires changes in GCC CD_CT scripts. In other words, the namelist.atmosphere should read config_physics_suite = 'mesoscale_reference_monan'

Type of Change

• Bug fix
• Hot fix
• New feature
• Improvement to existing functionality
• Code refactoring
• Code optimization
• [ X] Other: Physics tuning

Testing and Quality

• Code was written following MONAN’s DTN-01 (Coding Standard)
• Compilation and execution tests of the model were executed
• Test with the debug flag was executed
• Results are reproducible with the default configuration

Scientific Impact

This version should improves the forecast precipitation in the first 24h of the time integration. Because of MONAN uses a analysis data from a different model for its IC, we found that the 1st day always have a sub-estimation of the global mean precipitation. In my experiments, this version improves this systematic bias. In the future, this configuration should be revisited when the data assimilation of MONAN becoming available and start producing its own analysis for IC.

Bom dia João e colegas. Obrigado pela informação. Vamos usar esta versão para as rodadas de 10 km na Jaci. Por favor, me avise assim que a esta nova versão já estiver sendo executada no lugar da atual. Saulo
