How to append multiple data arrays into one varibale of xarray dataset?

[hosseinshirali]

i am new in this field and i need a small help. i just want to know that, what is the best way to append multiple data arrays in a variable of a xarray dataset?
each data array has a different time and value but has the same x,y coordinates same as dataset. i tried ds[variable_name] = da but it works only for the first data array. i want to create a function that gets data arrays and puts them into one variable of the dataset and updating the time dimension of the dataset. thanks for your help

you might want to have a look at the relevant section in the documentation. Usually, xr.concat with dim="time" should be enough, but xr.combine_by_coords, xr.combine_nested or xr.merge could work, too.

yes, xr.merge solved my problem
