@fmaussion, thanks again for your time!

Which is what I think you do in salem.

Oh, and to make the time slice work for WRF, I had to make the time variables consistent: python xds.rename( { time_dim: 'time', time_var: 'time', }, inplace=True )

OK. That is good to know. In this case, I don't know the name if the dimension beforehand, so I thought it might be preferable to do:

python data = data.loc[{self.lsm_time_dim: [pd.to_datetime(time_step)]}] instead of: python data = data.sel(**{self.lsm_time_dim: [pd.to_datetime(time_step)]}) What are your thoughts?

OK. I feel silly now. I thought I should have been using loc[] Thanks @fmaussion for that.
