Atmospheric output for some commonly used configurations of NorESM2¶
In preparation for CMIP6 and the required model output for the various MIPs, NorESM2 has been set up with different configurations, all run as AMIP using the compset NF2000climo (on 2 degrees) in noresm-dev (commit 7757f2d8258d5f84e960db12f840afebc69d7856 from October 30’th 2018).
With standard set-up of the model, the monthly output variables (1, 2 and 3 D) are:
Adding history_aerosol = .true. to user_nl_cam gives the following additional 577 variables (+ ca. 13 % CPU-time)
Furthermore including #define AEROFFL to preprocessorDefinitions.h gives 8 additionally variables (+ ca. 5% CPU-time)
and when also #define AEROCOM is activated there, we additionally get the following 149 variables (+ ca. 13% CPU-time)
Finally, also taking out COSP data (./xmlchange –append CAM_CONFIG_OPTS=’-cosp’), the following 57 output variables (of which 7 are 4 D) are added to the output (+ ca. 10% CPU-time):
