Adding new variables to an existing network¶
Each network has a list of variables (from raw file) that are known to
where ‘network_name’ is the name of newtork lke ‘gcnet’, ‘promice’, etc.
If you want to modify JAWS and add new variables to a network, you need to modify following 3 files i.e.
In this example, we will add two new variables (‘Sensible Heat Flux’ and ‘Latent Heat Flux’) to PROMICE.
Step 1: Add variable names to columns.txt of that network in same order as they are in raw file. In our example raw file, ‘sensible_heat_flux’ comes after ‘wind_direction’ and is followed by ‘latent_heat_flux’. So, we will add new variables like this:
Step 2: Next, we will populate attributes information for the newly added variables in ds.json as following:
Step 3: Then, we will add the encoding information in encoding.json as below:
Step 4: The final step is only for
AAWS, GCNet and PROMICE networks. You will need to update the count
of variables in jaws/common.py. Since we have added two variable, so we will update the
len(input_file_vars) from 44 to 46 as following:
