File extension zarr is used for an open-source specification format for storing chunked data by dividing the arrays into chunks and compressing each chunk. 

It is a generic data format for Scientific Array Data and may contain geospatial data like Oceanography data but also Microscopy data. 

The Zarr format supports a range of compression and chunking options, which can be tuned to optimize for different access patterns (e.g., reading small slices versus reading entire arrays). It also supports metadata storage, making it a self-describing format.
