GIRAFE Firecube Plugin

Ingest GIRAFE netCDF products into a zarr store using firecube. The plugin provides two chunk layouts optimized for timeseries (Spaghetti) and maps (Lasagna).

Installation

pip install firecube-girafe

Usage

Ingest using layout optimized for maps

firecube ingest girafe \
   --input-data /input/girafe \
   --target file:///output/girafe-maps.zarr \
   --product-name girafe \
   --write-mode direct \
   --option layout=maps

Ingest using layout optimized for timeseries

firecube ingest girafe \
   --input-data /input/girafe \
   --target file:///output/girafe-timeseries.zarr \
   --product-name girafe \
   --write-mode direct \
   --option layout=timeseries

You can also use a custom chunk layout

firecube ingest girafe \
   --input-data /input/girafe \
   --target file:///output/girafe-timeseries.zarr \
   --product-name girafe \
   --write-mode direct \
   --option zarr_chunk_shape='{"time": 10, "lat": 10, "lon": 10}'

After ingestion, compute something

import xarray as xr

with xr.open_zarr(
    "/output/girafe-timeseries.zarr", group="default", consolidated=False
) as ds:
    res = ds.sel(lat=0, lon=0, method="nearest").compute()
    res["precipitation"].plot()
