The training set consists of 2,154,021 rows and the test set of 280,961 rows. Each record is uniquely identified by its coordinates (latitude, longitude, and date) and contains the following features:

• TWS_t — Total Water Storage for month t
• SPEI_01 to SPEI_12 — Standardised Precipitation Indices at 1, 3, 6, and 12 month timescales timescale
• SOIL_MOISTURE_t — Near-surface soil moisture for month t

The corresponding target values (TWS for t+1) for the training set are provided in a separate CSV file.

Participants are encouraged to experiment with approaches that capture both temporal dynamics and spatial patterns at a global scale.
