# ADRISHTA: 3D Subsurface Ocean AI Dataset (North Indian Ocean 2024–2026)

This repository contains the complete open scientific assets for the ADRISHTA Subsurface Ocean AI system:
- **Master Zarr Store** (`zarr/oceanembed_multiyear_2024_2026.zarr`): Harmonized 7-channel satellite surface inputs + 15 standard INCOIS target depths at 0.25° resolution across 2024-01-07 to 2026-10-03 (148 daily/weekly snapshots).
- **In-Situ ARGO Ground Truth** (`argo/`): 134 real physical CTD float soundings from the Coriolis GDAC / INCOIS array.
- **Model Checkpoints** (`checkpoints/`): Frozen Physics-Constrained and Baseline OceanEmbedNet weights.
- **Raw Multi-Parameter Copernicus Data** (`raw/`): 3D potential temperature, salinity, currents, and sea surface height NetCDFs.
