A dataset plugin for climetlab for the dataset maelstrom-radiation.

maelstrom-radiation

A dataset plugin for climetlab (https://climetlab.readthedocs.io/en/latest/) for the dataset maelstrom-radiation.

Datasets description

This data is for learning the emulation of the ECMWF radiation scheme, using the McICA solver, found in the ecRad package (https://github.com/ecmwf/ecrad). Building an accurate emulator of radiative heating could accelerate weather and climate models partially by enabling the use of GPU hardware within our models.

There are two datasets, allowing different views on the same data:

1 : maelstom-radiation

Supports the to_xarray method and allows users to explore the data with all structure kept intact.

2 : maelstrom-radiation-tf

Loads the same data but from a shuffled and repacked into the TFRecord format. This dataset supports to_tfdataset which uses Tensorflow's dataset object.

Using climetlab to access the data

Both datasets and downloaded and explained in the demo notebook here https://git.ecmwf.int/projects/MLFET/repos/maelstrom-radiation/browse/notebooks/demo_radiation.ipynb

The climetlab python package allows easy access to the data with a few lines of code such as:

!pip install climetlab climetlab_maelstrom_radiation
import climetlab as cml
cml_ds = cml.load_dataset("maelstrom-radiation", subset="tier-1")
ds = cml_ds.to_xarray()

!or for the TFdataset version
cml_ds = cml.load_dataset("maelstrom-radiation-tf", subset="tier-1")
ds = cml_ds.to_tfdataset(batch_size=256)
