For demo-ing how to create Icechunk stores
This dataset is a small demonstration Icechunk repository built from NOAA Climate Data Record (CDR) AVHRR NDVI NetCDF files. The Icechunk repository stores metadata and virtual chunk references, while the original NetCDF data chunks remain in the public NOAA S3 bucket.
This example is intended for teaching cloud-native access patterns for archival NetCDF data using:
This example is based on a notebook by Rich Signell and modified by Eli Holmes. Notebook used to create this demo virtualizarr_ndvi_cdr_append-cloud.
This repository contains an Icechunk dataset. The Icechunk repository does not copy the full NDVI data out of the original NetCDF files. Instead, it stores virtual references that point back to byte ranges in the original public NOAA S3 files.
That means:
The source NetCDF files are from the public NOAA CDR NDVI bucket:
Example source file:
The Icechunk repo contains virtual chunk references back to these source NetCDF files.
Replace the bucket and prefix below with the Source Cooperative bucket and prefix for this dataset.

Please cite the original NOAA CDR NDVI product when using the data scientifically. This Icechunk repository is a derived access layer for demonstration and teaching purposes; the underlying data are from NOAA.
See the license and use constraints for the original NOAA CDR NDVI product. This repository provides virtual access to that public source data and does not modify the original NetCDF files.
