- Recreate biweekly renku datasets with `float32` single precision and newly uploaded data to [`climetlab_s2s_ai_challenge`](https://github.com/ecmwf-lab/climetlab-s2s-ai-challenge/releases/tag/0.7.0). Before `lead_time` in `tp` had a one day shift. These new renku datasets will be used by the [`s2saichallengescorer`](https://renkulab.io/gitlab/tasko.olevski/s2s-ai-competition-scoring-image/-/merge_requests/3). (#7, !9, https://renkulab.io/gitlab/aaron.spring/s2s-ai-challenge/-/issues/22, [Aaron Spring](https://renkulab.io/gitlab/aaron.spring))
- Order of processing gridded `RPSS` to final score: (#7, !9, [s2s-ai-competition-scoring-image!2](https://renkulab.io/gitlab/tasko.olevski/s2s-ai-competition-scoring-image/-/merge_requests/2), [Aaron Spring](https://renkulab.io/gitlab/aaron.spring))
1. `RPSS`
2. penalize where `NaN` submitted but value expected #7
3. `clip(-10,1)`: prevent too negative values
4. mean over `forecast_time`
5. spatially weighted mean [90N-60S]
6. mean over `lead_time` and `data_vars`
- Dont forget to `git add current_notebook.ipynb` also to ensure that consistent training pipeline and submission file are tagged, added to notebooks. (!9, [Aaron Spring](https://renkulab.io/gitlab/aaron.spring))
- Rerun [`ML_train_and_predict.ipynb`](https://renkulab.io/gitlab/aaron.spring/s2s-ai-challenge-template/-/blob/master/notebooks/ML_train_and_predict.ipynb) (!9, [Aaron Spring](https://renkulab.io/gitlab/aaron.spring))
- Fix typo in safeguards in [ML_forecast_template.ipynb](https://renkulab.io/gitlab/aaron.spring/s2s-ai-challenge-template/-/blob/master/notebooks/ML_forecast_template.ipynb): "We did NOT use `test` explicitly in training or implicitly in incrementally adjusting parameters."" (!8, [Aaron Spring](https://renkulab.io/gitlab/aaron.spring))

- fix `netcdf4` version to `1.5.4` for `opendap` to work lazily with `xarray` (!2, !7, [Aaron Spring](https://renkulab.io/gitlab/aaron.spring))
After this `v0.2` release, this CHANGELOG.md will describe all changes made in this template repository.
- update `README` how to join competition, please `git pull` if you forked before

- calculate `RPSS` with respect to climatology (not ECMWF anymore) ([Aaron Spring](https://renkulab.io/gitlab/aaron.spring))
- update `scorer`: https://renkulab.io/gitlab/tasko.olevski/s2s-ai-competition-scoring-image ([Tasko Olevski](https://renkulab.io/gitlab/tasko.olevski), [Aaron Spring](https://renkulab.io/gitlab/aaron.spring))
- Averaged ECMWF RPSS skill value to beat at least: -0.0070
