+# Processed datasets for TSL
+
+This repository contains the processed data files used by the [Torch Spatiotemporal (TSL)](https://github.com/TorchSpatiotemporal/tsl) dataset classes. The files are kept with the layout expected by those classes, so they can be downloaded, unpacked, and built by TSL without an additional conversion step.
+
+The collection is intended primarily for reproducibility studies and benchmarks in TSL. It is not a new re-release of the underlying datasets: the datasets retain the provenance and usage conditions of their original sources. Please consult the original papers and providers before redistributing or using them.
+
+## Contents
+
+| Dataset | TSL class | Data | Processed size |
+| --- | --- | --- | --- |
+| PeMS03 | `tsl.datasets.PeMS03` | Traffic flow from 358 California sensors, sampled every 5 minutes from September–November 2018. | 26,208 × 358 × 1 |
+| PeMS04 | `tsl.datasets.PeMS04` | Traffic flow, occupancy, and speed from 307 San Francisco Bay Area sensors, sampled every 5 minutes from January–February 2018. | 16,992 × 307 × 3 |
+| PeMS07 | `tsl.datasets.PeMS07` | Traffic flow from 883 California sensors, sampled every 5 minutes from May–August 2017. | 28,224 × 883 × 1 |
+| PeMS08 | `tsl.datasets.PeMS08` | Traffic flow, occupancy, and speed from 170 San Bernardino sensors, sampled every 5 minutes from July–August 2016. | 17,856 × 170 × 3 |
+| PeMS-Bay | `tsl.datasets.PemsBay` | Traffic readings from 325 San Francisco Bay Area sensors, sampled every 5 minutes from January–June 2017. | 52,128 × 325 × 1 |
+| METR-LA | `tsl.datasets.MetrLA` | Traffic readings from 207 Los Angeles loop detectors, sampled every 5 minutes from March–June 2012. | 34,272 × 207 × 1 |
+| Air Quality | `tsl.datasets.AirQuality` | PM2.5 measurements from 437 stations in 43 Chinese cities, sampled hourly from May 2014–April 2015. Includes the 36-station Beijing subset. | 8,760 × 437 × 1, or 8,760 × 36 × 1 |
+| LargeST | `tsl.datasets.LargeST` | Five years of California traffic readings from 8,600 sensors, sampled every 5 minutes from 2017–2021. TSL can select CA, GLA, GBA, or SD subsets and individual years. | 525,888 × 8,600 × 1 |
+| PV-US | `tsl.datasets.PvUS` | Synthetic photovoltaic power production for 5,016 US plants, sampled every 10 minutes. East and west zones are provided separately. | 52,560 × 5,016 × 1 |
+
+Dimensions above describe the main time-varying target. Some datasets also include masks, distances, locations, metadata, occupancy, speed, or adjacency information.
+
+## File layout
+
+The layout is part of the interface with TSL:
+
+```text
+air/
+  air_quality.zip               # full437.h5 and small36.h5
+traffic/
+  metr_la.zip                   # METR-LA data and sensor metadata
+  pems03.zip                    # PeMS03 data and distances
+  pems04.zip
+  pems07.zip
+  pems08.zip
+  pems_bay.zip                  # PeMS-Bay data and sensor metadata
+large_st/
+  2017/data.h5 ... 2021/data.h5
+  sensors.zip                   # adj.npz and metadata.csv
+pv_us/
+  east.h5
+  west.h5
+```
+
+The ZIP files should remain archives. They contain the raw files that the corresponding TSL class expects when it runs its `download()`/`build()` pipeline. LargeST is split by year so callers can request only the years they need.
+
+## Using the data with TSL
+
+After installing TSL, extract the relevant archive into a loader root (or arrange the uncompressed files in the layout expected by the class), then pass that root to the class:
+
+```python
+from tsl.datasets import AirQuality, LargeST, MetrLA, PeMS04, PvUS
+
+air = AirQuality(root="/path/to/extracted/air_quality")
+traffic = PeMS04(root="/path/to/extracted/pems04")
+metr = MetrLA(root="/path/to/extracted/metr_la")
+large = LargeST(root="/path/to/ProcessedDatasets/large_st", year=2019)
+solar = PvUS(root="/path/to/ProcessedDatasets/pv_us")
+```
+
+For an automatic download through TSL, use a TSL version whose dataset URLs point to this Hugging Face repository. The repository preserves the filenames needed by the loaders; the URL migration itself belongs in the TSL dataset class definitions.
