Marshmellow
Port activity, atmospheric observations, and reproducible graph inputs.
This public research collection contains the retained data used in a port-environment feasibility study, including the Los Angeles / Long Beach demo. Release 2026-10-28 contains 235 data and metadata files, 447.9 MB (447861818 bytes), plus documentation and checksums. It is a collection of real samples and derived tables, not a complete mission archive or an emissions-attribution benchmark.
Use the configuration selector above to explore port completeness, daily or monthly gases, hourly AIS/NO₂, monitor locations, and the three satellite channels. All splits are called sample; these are convenient table views, not train/test partitions.
What is available
| Source | Retained coverage | Contents and role |
|---|---|---|
| NOAA MarineCadastre AIS | 15 July 2024 UTC, one national U.S. day | Original 309 MB GeoParquet; 9,842,280 reports in the retained file. Derived routes cover 20 earlier port windows and the combined LA/LB demo. |
| EPA AirData | 2024 daily gas files and hourly NO₂; 2024/2025 annual summary snapshots | Original national ZIPs. Includes NO₂, SO₂, CO, O₃, NO/NOx/NOy, VOC and hazardous-air-pollutant groups. Station availability varies. |
| NASA TEMPO | Small numeric exports for 1 January 2024, and LA/LB 15 July 2024 at 20:18:25 UTC | NO₂ tropospheric column, HCHO column and total O₃; retained V03 subsets and service metadata. |
| Carbon Mapper / ASU airborne data | Selected harbour observations, including 21 June 2023 at 18:02:43 UTC | Quantitative methane-enhancement GeoTIFF plus small candidate assets and detection catalogues. Noncommercial terms apply. |
| Copernicus Sentinel-5P | July 2024 catalogue queries | Footprints/times for availability screening. No Sentinel-5P concentration granules are included. |
| NOAA GOES-16 | 1 January 2024, one paired scan near 19:11 UTC | Aerosol optical depth and cloud-mask NetCDF samples. These are not gas concentrations. |
| NGA World Port Index | 2019 snapshot, 3,630 entries | Port locations from a public ArcGIS mirror; includes non-cargo ports and terminals. |
| Natural Earth; USDA/USGS | Retained reference geometry and LA/LB imagery | Background context. Imagery acquisition dates are unverified; service refresh dates are not observation dates. |
| Hong Kong open-data pilot | 1 January 2024 | Small archived air-quality and vessel-arrival samples, separate from the U.S. demo. |
Start small
Download only the derived LA/LB tables first:
hf download Celsia/Marshmellow --repo-type dataset \
--include "outputs/la-lb-demo-2026-10-26/*.csv" \
--local-dir ./Marshmellow
Or load one table:
from datasets import load_dataset
hourly = load_dataset("Celsia/Marshmellow", "la_lb_hourly_ais_no2", split="sample")
The full release is still under 0.5 GB:
hf download Celsia/Marshmellow --repo-type dataset --local-dir ./Marshmellow
cd Marshmellow

Layout and provenance
data/<source>/: retained source archives, rasters, geography and supporting metadata.outputs/: derived CSV tables, route arrays and analysis descriptions used by the graphs.configs/port-complexes.json: the LA/LB and NY/NJ grouping definitions.- MANIFEST.json: each payload file's size, SHA-256, origin category and any metadata sanitization.
- checksums.sha256: checksums for all released files except the checksum list itself.
- DATA_DICTIONARY.md: units, field meanings and limitations.
- SOURCES.md and LICENSE: attribution and source-specific conditions.
Measurement ZIPs, GeoParquet, GeoTIFFs, NetCDFs, geometry and analysis arrays retain their original bytes. Temporary signed download parameters were removed from the two Carbon Mapper catalogue exports and their receipts; a local path field was removed from the Natural Earth receipt. These public metadata copies are explicitly marked metadata_sanitized. The original local files were not edited. Original source receipts refer to original hashes; the release manifest is authoritative for the sanitized copies.
Private attachments, account information, local delivery records and private processing code are excluded. Provider manuals are linked rather than copied. Earlier multi-port outputs are retained for reproducibility; only the demo's complex configuration merges LA/LB and NY/NJ, so do not sum overlapping historical port windows.
Interpretation boundaries
Different measurement supports. Surface monitor values are ambient concentrations; TEMPO values are atmospheric columns; the high-resolution methane image is column enhancement above background in ppm·m. They cannot be ranked as “the three most concentrated gases” by their raw numbers.
Resolution. The RGB overview uses native 0.02° TEMPO cells, approximately 1.85 × 2.22 km here. A smooth-looking display cannot supply missing detail. The separate 3.5 m methane raster was measured by the airborne Global Airborne Observatory, not a satellite. No matched three-gas plume at that fine resolution has been established.
Time and attribution. The 2023 plume is not matched to the 2024 AIS day. Its provider sector is other; this collection does not identify a vessel, terminal or operator as its source. Same-day AIS and satellite scan-start matching does not establish per-pixel simultaneity or causality.
Quality and completeness. TEMPO exports lack retained pixel-level QA flags; negative/missing values remain available, and display masking is not retrieval validation. Satellite catalogue overlap is potential coverage, not a valid-pixel score. Ground monitoring outside the U.S. subset is not assessed by the EPA score. Nearby ports can share the same monitor.
Correlation. The hourly demo has only 24 paired hours. Its cargo/tanker-count versus NO₂ Spearman coefficient is about −0.265 and is descriptive. Annual gas correlations do not control meteorology; NOx also overlaps chemically with NO and NO₂.
