Pre-release
Side-by-Side HYD Release
This release introduces the side-by-side hydrology feature. A test case has been added to run two side-by-side hydrology components. This compset is available as sbys_tuolumne_hyd.ens002.ldas. This feature is a is a prerequisite to an online coupled LND-HYD ensemble.
LISHydro: LIS Hydro Driver (ESM)
The LIS-Hydro driver will automatically generate multiple hydrology instances based on the runtime configuration variable set in lishydro.runconfig. PET pairs set in lishydro.runconfig define the PET boundaries for each hydrology instance. PET lists for different instances must not overlap.
pets_hyd: 0 3 4 7 8 11 ... # in this example each instance is given 4 processors
multi_instance_hyd: true # generate multiple hydrology instances
instance_count_hyd: x # x is the number of instances
Each hydrology instance is suffixed with an instance identifier.
HYD-01, HYD-02, HYD-03, ..., HYD-16, ..., HYD-x
The multi_instance_hyd attribute is passed down to each hydrology instance.
HYD: WRF-Hydro
WRF-Hydro references the NESII/wrf_hydro_nwm_public repository forked from NCAR/wrf_hydro_nwm_public. WRF-Hydro has been updated to support multiple instances using a call to change working directory in the WRF-Hydro cap. If the multiple instance attribute is set to true then the WRF-Hydro cap will change the working directory to a subdirectory with the same name as the component.
multi_instance_hyd: true
