NetCDF to Zarr

This repository contains code for converting NetCDF files to Zarr stores. Basic examples follow below.

Examples

List of Files

import zarr
from netCDF4 import Dataset

from convert import netcdf_to_zarr

ds_1, ds_2 = 'path_to_ds_1.nc', 'path_to_ds_2.nc'
store = zarr.DirectoryStore('store.zarr')
netcdf_to_zarr([ds_1, ds_2], store, 'Time')

List of Files in S3

import zarr
from netCDF4 import Dataset

from convert import netcdf_to_zarr
from iterators import S3BasicIterator

# Iterate through S3 objects without downloading all at once
ds_iterator = iter(S3BasicIterator('bucket_name', ['key_1', 'key_2'], 'path_to_download_folder'))
store = zarr.DirectoryStore('store.zarr')
netcdf_to_zarr(ds_iterator, store, 'Time')
