This page shows how to set up an offline land analysis experiment by prepIFS based on CY48R1 by prepIFS (including snow depth analysis).
...
- You can change settings for offline land surface model. In this case, horizontal resolution and time step are changed to the same as the seasonal prediction system.
- In the default settings, atmospheric forcing is retrieved from ERA5.
- 'FREQ_PP_OSM' must be set to 1 if you set up an offline land analysis experiment.
...
- If you run an experiment at high higher resolution, you might have to change NPES_FC and THREADS_FC. NPES_FC=1 is enough for TCo319 experiment.
- If you would like to change horizontal resolution, the following page will be useful: Old documentation of Offline ECLand simulations
...
- You can change settings for offline land analysis here.
- LSEKF_SM: activate soil moisture analysis
- LSEKF_SD: activate snow depth analysis
- LMONTHLY_ARCH: In order not to avoid high load on MARS by archiving output frequently, it is better to set it On. This is used for offline land analysis experiment only.
- LSAVE_SEKF: To save the SEKF output in ECFS, including increments, innovations and Kalman gains, select LSAVE_SEKF to "ON"
