h2mare¶
Geospatial processing pipeline for climate and ocean data.
H2MARE downloads, converts, and harmonises multi-source oceanographic and atmospheric data into analysis-ready formats. It streamlines the full pipeline from raw API download through regridding and point extraction, optimised for large-scale spatiotemporal analysis.
Features¶
| Feature | Description |
|---|---|
| Multi-source integration | CMEMS, AVISO, and ERA5 via their native APIs |
| Format conversion | NetCDF / GRIB → Zarr (chunked, compressed) |
| Compilation | Regrid all variables to a common 0.25° daily grid |
| Extraction | Extract time series at CSV points or SHP geometries |
| Incremental updates | Infers missing dates from the store; downloads only the gap |
| Catalog tracking | Metadata index per variable for fast Zarr range queries |
| Parquet store | Hive-partitioned Parquet store managed by ParquetIndexer with lazy scanning, overlap resolution, and built-in visualisation |
