Quickstart
There is no separate quickstart notebook. The same notebooks that produced the manuscript results are the entry points for everything: only the config you point them at changes.
| Notebook | Stage |
|---|---|
02_lseqmdl_bias_correction.ipynb |
LS, LSEQM, LSEQM+DL correction |
03_measuring_performances.ipynb |
Per-pixel WMO metrics |
04_qa_framework.ipynb |
Continuous Quality Index |
05_station_validation.ipynb |
Independent BMKG station checks |
06_visualisation_hub.ipynb |
Figures and Taylor diagrams |
All five live in notebooks/ and open directly in Google Colab.
What you choose: the AOI
You have two options. Both use the same notebooks. The only difference is which config file you point them at.
Option A - Bali example (recommended for first run). Uses config_bali.yml and the 11 MB Bali bundle that ships in the repository under data/example_bali/. The nb02 bias-correction step finishes in ~15 minutes on a free Colab CPU; the full nb02-nb06 chain takes a bit longer.
Option B - Full Indonesia. Uses config.yml and the Indonesia input bundle published on Zenodo. End-to-end is heavier (hours on Colab CPU, much faster on GPU). Use this once Bali looks correct.
Step-by-step (Colab)
1. Get the repository and data into Drive
# In Drive, expected layout after this step:
# /MyDrive/hybrid-bias-correction/
# src/
# notebooks/
# config.yml
# config_bali.yml
# data/example_bali/ <- ships with the repo for Option A
# data/input/ data/output/ data/mask/ <- from Zenodo for Option BThe simplest path: download the repository as a ZIP, upload it to Drive, and unzip into /MyDrive/hybrid-bias-correction/. For Option B, also drop the Zenodo bundle into /MyDrive/hybrid-bias-correction/data/.
2. Open notebook 02 in Colab
The notebook opens with the GitHub copy; saving will prompt for a Drive copy. Same approach for nb03, nb04, nb05, nb06 - badges on their respective tutorial pages.
3. Mount Drive
Run the Section 1 cell. It mounts /content/drive and unmounts cleanly if a stale mount is present.
4. Point at the right config
Every notebook has the same toggle near the top of Step 1 (Setup Environment):
# ===========================================================================
# AOI config selector
# 'config.yml' -> full Indonesia (Zenodo input/output bundle)
# 'config_bali.yml' -> Bali example (ships with the repo, ~11 MB)
# Edit this single line to switch the entire pipeline between the two.
# ===========================================================================
CONFIG_FILE = 'config.yml'To run the Bali example, change the last line to:
CONFIG_FILE = 'config_bali.yml'Nothing else needs editing. Paths, parameters, and output directories are all resolved from whichever config is selected. The same toggle exists in nb02, nb03, nb04, nb05, and nb06 - keep them in sync (all five on 'config.yml' for the full run, all five on 'config_bali.yml' for the Bali example).
5. Verify and run
After the setup cell prints, you should see Bali-scoped paths:
Configuration loaded successfully:
Main directory : /content/drive/MyDrive/hybrid-bias-correction
Input directory : /content/drive/MyDrive/hybrid-bias-correction/data/example_bali
Output directory: /content/drive/MyDrive/hybrid-bias-correction/data/example_bali/output
IMERGL file : .../bali_imergl.nc4
CPC file : .../bali_cpcuni.nc4
Mask file : .../bali_mask.nc
From there, run cells in order. The batch correction loop in Step 11 writes outputs to data/example_bali/output/. Then open notebooks 03 through 06 in the same Drive session to compute metrics, QA, station validation, and figures - each follows the same setup pattern.
Step-by-step (local)
Same flow, with two differences:
- Skip the Drive mount cell.
- In the setup cell, set
ROOTto your local checkout path instead of the/content/drive/...default:
ROOT = '/Users/you/projects/hybrid-bias-correction' # or your Windows pathWhat you get
After running notebook 02 over all 36 dekads, your output/ tree looks like this (Bali example):
data/example_bali/output/
corrected_ls/ 36 NetCDFs
corrected_lseqm/ 36 NetCDFs
corrected_lseqmdl/ 36 NetCDFs
trained_models/ 36 .keras + normalisation JSONs
station_density/ confidence mask NetCDF
After notebooks 03 - 06, the rest of the tree is populated:
metrics_{ls,lseqm,lseqmdl}/ per-pixel WMO metrics
quality_{ls,lseqm,lseqmdl}/ CQI components
station_validation/ CSVs and Taylor diagrams
figures/ PNGs
