CFE output files (cat-*.csv) results are all zero

[shahab122]

Hi everyone, I have run CFE using NGIAB for the Sipsey River basin (VPU # 03W) in Alabama. As I was checking the model outputs (e.g., "cat-117770.csv"), I found all values in the"cat-117770.csv" file to be zero. This is the case for all catchment csv files. I used "latest-86" image as I was running CFE within NGIAB on Black Warrior. I am not sure what went wrong as I followed the steps mentioned here: https://github.com/CIROH-UA/NGIAB-CloudInfra.

@shahab122. The easy, useless answer is that those are the default values your configurations is asking the SLOTH module to create as gap-filler for a few values that have to be supplied to CFE.

But what we really need to do is:
a) We need to figure out where the real output from your CFE simulations are going (which is what I believe was your real concern; please confirm).
b) We need to figure out if the 0 values for EVAPOTRANS, *ice_fraction, and sloth_smp are valid for the conditions of your simulation or if they were just default values to permit successful simulation. The EVAPOTRANS parameter has a companion parameter in the CFE model that may be taking precedence in the simulation, for instance. Or, the *_ice_fraction value could be valid at zero if there are no freezing temperatures for your simulation.

This is the sloth configuration here that is producing csv output files:

{
    "name": "bmi_c++",
    "params": {
        "name": "bmi_c++",
        "model_type_name": "SLOTH",
        "main_output_variable": "z",
        "init_config": "/dev/null",
        "allow_exceed_end_time": true,
        "fixed_time_step": false,
        "uses_forcing_file": false,
        "model_params": {
            "sloth_ice_fraction_schaake(1,double,m,node)": "0.0",
            "sloth_ice_fraction_xinan(1,double,1,node)": "0.0",
            "sloth_smp(1,double,1,node)": "0.0",
            "EVAPOTRANS": "0.0"
        },
        "library_file": "/dmod/shared_libs/libslothmodel.so",
        "registration_function": "none"
    }
}

Two options here, one, change the order of the multi bmi module definitions so that sloth comes first in the list and CFE is last. By default, ngen will only output the output variables of the LAST modules defined in a multi-bmi model definition. The other option is to use the optional configuration key

"output_vars" : [ "Q_OUT", "OTHER_KNOWN_OUTPUT_VAR"]

With this list, you can explicitly define any output variable available in any of the modules, and the order they will appear in the output CSV file.

First option works for me. It produces the output cat-*.csv files with the outputs for both serial and parellel run. Thank you Nels, I will add the updated one to the AWI_002

[arpita0911patel]

Updated AWI_03W_113060_002.tar.gz in S3 bucket with the new config file.

@shahab122, could you please review the most recent updates and confirm that everything appears satisfactory on your end? Please inform us of any issues or concerns. Thank you!

[shahab122]

@arpita0911patel It worked on my end as well. However, I would prefer the output results (i.e., *.flowveldepth.csv files) for each catchment id, not for each time step. So, each *.flowveldepth.csv file should contain all time steps. I think it would make further analysis easier. Thank you!

[arpita0911patel]

Thank you Shahab closing this ticket as it generates non zero output cat-*.csv files now.
For the flowveldepth file, created seperate ticket #61
