3D Clouds

This repository hosts the AI-ready datasets for the paper "Global 3D Reconstruction of Clouds & Tropical Cyclones." It contains paired 2D geostationary imagery (GOES, MSG, Himawari) and 3D vertical profiles (CloudSat/CALIPSO) used to train ML models for 3D cloud reconstruction, with a dedicated dataset for tropical cyclones.

Metadata Fields

LEVEL0

Field	Type	Description
`id`	`string`	Unique sample identifier within parent scope. Must be unique among siblings.
`type`	`string`	Sample type discriminator (FILE or FOLDER).
`taco:header`	`binary`	Binary TACOTIFF header (35 bytes + tile counts) for fast reading without IFD parsing
`stac:crs`	`string`	Coordinate reference system (WKT2, EPSG, or PROJ)
`stac:tensor_shape`	`list<item: int64>`	Raster dimensions [bands, height, width]
`stac:geotransform`	`list<item: double>`	GDAL affine transform
`stac:time_start`	`timestamp[us]`	Start timestamp (μs since Unix epoch, UTC)
`stac:centroid`	`binary`	Center point in EPSG:4326 (WKB)
`stac:time_end`	`timestamp[us]`	End timestamp (μs since Unix epoch, UTC)
`stac:time_middle`	`timestamp[us]`	Middle timestamp (μs since Unix epoch, UTC)
`geotiff:stats`	`list<item: list<item: float>>`	Per-band statistics (List[List[Float32]]): categorical mode returns class probabilities, continuous mode returns [min, max, mean, std, valid%, p25, p50, p75, p95]
`cloud3d:satellite`	`string`	Geostationary satellite platform (GOES, HIMAWARI, or MSG)
`cloud3d:cyclone`	`bool`	Whether the sample contains tropical cyclone imagery

`geoenrich:elevation`	`float`	Mean elevation in meters (GLO-30 DEM)
`geoenrich:precipitation`	`float`	Mean annual precipitation in mm estimated from GPM data
`geoenrich:temperature`	`float`	Mean annual temperature in °C estimated from MODIS LST data
`geoenrich:admin_countries`	`string`	Country name at centroid location
`internal:current_id`	`int64`	Current sample position at this level (0-indexed). Enables O(1) random access and relational JOINs (ZIP, FOLDER, TACOCAT).
`internal:parent_id`	`int64`	Foreign key referencing parent sample position in previous level (ZIP, FOLDER, TACOCAT).
