Sentinel-2 Cloud Property Retrievals over the UK and India
Rendered per-scene quicklook layers of cloud optical and microphysical properties
retrieved from Sentinel-2 (MSI) Level-1C imagery over eight tiles (four in the UK
and four in India). These images power the interactive report at
asterisk-labs-clouds-decoded-rain-check.static.hf.space. Cloud properties are estimated with the clouds-decoded retrieval code, developed as part of the clouds decoded project funded by ARIA.… See the full description on the dataset page: https://huggingface.co/datasets/asterisk-labs/clouds-decoded-rain-check.taco-api-fixtures
TACO API Fixtures
A deterministic collection of 50 small TACO datasets whose payloads are all
Rumi files. The fixtures exercise TACO contracts, metadata hierarchies,
FOLDER and ZIP containers, ZIP partitioning, TACOCAT consolidation, generated
locations, and local or remote range reads.
They are API fixtures, not training data or a scientific benchmark. Spatial
and temporal metadata generated here is intentionally synthetic.

The repository combines ten… See the full description on the dataset page: https://huggingface.co/datasets/asterisk-labs/taco-api-fixtures.rumi-api-fixtures
Rumi API Fixtures
A small, deterministic collection of Earth-observation arrays encoded as Rumi
files.
This repository exists to test the Rumi API and its stateless remote range
reads through Karu. It is not a training dataset, a scientific benchmark, or a
general-purpose imagery archive.
What this dataset tests
The fixtures cover:
complete and windowed reads;
band selection and ordering;
temporal selection;
batch reads with rumi.read_many;
different Rumi frame… See the full description on the dataset page: https://huggingface.co/datasets/asterisk-labs/rumi-api-fixtures.double-asteriskiris-datasets

cozip GeoParquet Fixtures
A small, generated collection of Flat-profile cozip archives for testing
remote random access and the cozip playground.
Four of the five archives use a GeoParquet __metadata__ manifest, so their
features render directly on the playground map. The remaining archive is a
plain Flat manifest used to verify the non-geospatial fallback.
All archives conform to cozip specification 0.1.0, binary format version 1,
and Flat profile 1. They use the standard .zip… See the full description on the dataset page: https://huggingface.co/datasets/asterisk-labs/cozip-api-fixtures.
