how could we have available_variables give out different list of variables based on the dataset type if all variables are in one dictionary?

yeah that's why I did them separately, especially because the BGC variables are non-overlapping

I suggest using a single "master" copernicus_bgc_monthly_dataset_variable_names, and then writing out the available variable names explicitly in these functions. That way we have a single readable reference for all of the variables that can be downloaded from copernicus. It might become important as the number of variables grows.

Ok I reverted to a 'master' dict copernicus_dataset_variable_names and wrote out the variables explicitly in the avaiable_variables function. Is that what you were thinking?

yes, thank you! I can eliminate the repeated code by creating a more organized type hierarchy. do you mind if I commit to your branch?
