tams.data.get_imerg(time_or_range, *, version='07', run='final', parallel=False, **kwargs)#

Stream GPM IMERG L3 precipitation from NASA Earthdata.

https://gpm.nasa.gov/data/directory

This is half-hourly 0.1° (~ 10-km) resolution data. Each HDF5 file contains one time step. Each time step represents the mean precipitation rate for the half-hourly period that starts at the indicated time (i.e., left-labeled).

Note

The Python packages earthaccess and h5netcdf are required. Additionally, you must have a NASA Earthdata account (see https://earthaccess.readthedocs.io/en/stable/howto/authenticate/ for more info).

Parameters:

  • time_or_range (Any | tuple[Any, Any]) – Specific time or time range (inclusive) to request.

  • version (str) – For example: ‘06’, ‘07’.

  • run (str) – ‘early’ and ‘late’ are available in near-realtime; ‘final’ is delayed by a few months. See what’s available at NASA GES DISC.

  • parallel (bool) – Passed to xarray.open_mfdataset(), telling it to open files in parallel using Dask. This may speed up loading if you are requesting more than a few hours, especially if you are using dask.distributed.

  • **kwargs – Passed to earthaccess.login().

Return type:

xarray.Dataset
