xarray and IMERG precip files

[jules32]

xarray opens the IMERG precip files in AWS S3 bucket without any error message.
But they have zero coordinates or data. Does someone have an xarray example of how to open that data?

This was a question via email from a 2022 NASA Openscapes Champion; we will begin answering these sorts of questions here so we all can learn from them

From @betolink:

He needs to pass group="Grid". Here is an example: https://notebooksharing.space/view/0c9b943bfe8ec599df7ecf667c0efc8450f4d3a4c55ce359acc6949a3cc832ee#displayOptions=

From @rupesh2:

It also works when you add decode_coords="all". Here is an example: https://github.com/rupesh2/atmospheric_rivers/blob/main/precipitation_rate_imerg.ipynb

From @battistowx, from GES DISC (where IMERG files are archived):

We don't have any IMERG tutorials that use Xarray, but there is one that uses h5py and also requires /Grid/ to access the data: https://github.com/nasa/gesdisc-tutorials/blob/main/notebooks/How_to_Read_IMERG_Data_Using_Python.ipynb
