merged auxil into packdata, etc. +- Reformat documentation and added more comments +- Rewrote tests as pytest files +- Reformated the config file as a python file +- Used ruff for reformatting and linting +- Added pre-commit checks and a Github workflow for CI checks +- Added input features (std of some variables like Qair, Psurf, etc.) +- Increase Nc values (by a factor of 2) +- Instead of averaging over the whole time span, only take monthly averages and separate data per year to increase dataset size +- Simplified readvar.py +- Added new ML algorithm options: XGBoost, RandomForest, MLP, Lasso, Stacking Ensemble +- Combined all ML evaluation results into a single CSV table +- Implemented multithread parallelization to train a ML model per target variable in parallelization +- Added standard scaling to preprocess the data before ML training +- Updated README.md and CONTRIBUTING.md +- Added explanation of the varlist.json file + +## TODO +- Investigate (on bad-performance variables): feature importance, target variable correlation, sample size + +## Performance Benchmark + +### Separated Years +| Algorithm | R2 | slope |
