Himawari AHI ARCO Index This Dataset repo is the lightweight index and documentation surface for the Himawari AHI ARCO collection. The large Zarr payloads live in the public Hugging Face Storage Bucket: The repo keeps small metadata files such as .manifest.json and .coverage.json . New formal ARCO payloads should be published to the bucket, not to this Dataset repo. Available Bucket Payloads B13/B09/B10 formal products are planned as bucket first products after canary validation. Pilot payloads may still appear in this repo until they are either migrated or retired. Direct Bucket Access Store Contents Each monthly ARCO Zarr store contains: Missing source times are kept on the regular 10 minute UTC time grid. For those times, the band array reads as NaN , source present is 0, and source time index is 1. Repository Role This repo is intentionally small: The large B03/B08 Zarr payloads have been copied and validated in the bucket. They are removed from this repo so the Dataset repo remains a lightweight catalog instead of a second large storage copy.
