NOAA / JMA Himawari data distribution terms Modified from original

Attribution

Himawari-9 data: Japan Meteorological Agency (JMA), distributed by NOAA. Processing: AtmoSeq.

Used for

True-color and visible/infrared composites, B07/B13/B15 brightness temperatures, event-time infrared samples

Notes

JMA Himawari-9 data distributed by NOAA is obtained through delivery nodes. AtmoSeq combines channels, extracts brightness temperatures, subsets or reprojects data. Results are modified products, not unchanged official imagery. Credit JMA and NOAA, retain the data time, and do not imply endorsement.

Attribution

Cloud products: NOAA/NESDIS, based on JMA Himawari-9 AHI observations. Subsetting and conversion: AtmoSeq.

Used for

Cloud-top properties, optical depth, cloud mask and phase; event validation

Notes

Cloud products from the public NOAA Himawari-9 bucket are sampled at event times, subset and converted when enabled. Product-specific L2 rights and redistribution conditions still require verification; a public bucket is not a blanket public-domain license.

JAXA Terms of Use of Research Data Modified from original

Attribution

Himawari aerosol research products: JAXA / NIES, based on JMA observations. Processing: AtmoSeq.

Used for

Regional aerosol optical-depth samples and sunset-model validation

Notes

P-Tree L2 and L3 hourly or daily products are subset and converted when enabled. The official guide permits commercial use of eligible Himawari products from 2026-02-01 00:00 UTC; earlier data remains restricted. JAXA requires advance notification of commercial research-data use. Data dates, notification and product-specific credits remain to be confirmed.

NOAA/NWS public-domain data policy (with exceptions) Modified from original

Attribution

Source: NOAA/NWS/NCEP GFS. Data extraction and processing: AtmoSeq.

Used for

Global weather grids, atmospheric profiles and inputs for sunset calculations

Notes

Fields from NOAA public GFS data are obtained through delivery nodes and converted to multiband rasters when enabled. NOAA/NWS data is generally public domain unless otherwise marked. Do not present processed output as an official product or imply NOAA endorsement.

License

NOAA/NWS public-domain data policy (with exceptions) Modified from original

Attribution

Source: NOAA/NWS/NCEP GEFS. Data extraction and processing: AtmoSeq.

Used for

Aerosol grids, cloud ensembles, tropical-cyclone ensemble tracks and derived probabilities

Notes

Data from NOAA GEFS public storage and NCEP ensemble-track services is selected by member or field, converted and used for derived calculations when enabled. Platform-derived probabilities are not official NOAA forecasts or endorsements; specific rights notices take precedence.

CC BY 4.0 + ECMWF Terms of Use Modified from original

Attribution

This service is based on data and products of the European Centre for Medium-Range Weather Forecasts (ECMWF). Source: www.ecmwf.int. Processing: AtmoSeq.

Used for

Deterministic grids, ensemble cyclone tracks and inputs for derived calculations

Notes

Applies to the IFS/AIFS Open Data subset actually obtained, when enabled. AtmoSeq selects fields, converts formats or parses ensemble tracks. Retain source, CC BY 4.0 license links and change notices; data redistribution also requires the ECMWF copyright notice for the relevant year. ECMWF disclaims responsibility for errors, omissions, availability and consequences of use; see the linked terms.

Attribution

Source: Deutscher Wetterdienst (DWD), ICON. Remapping and processing: AtmoSeq.

Used for

Global weather grids and inputs for sunset calculations

Notes

DWD Open Data is obtained through delivery nodes and remapped to latitude/longitude grids when enabled. The official Open Data notice points to current DWD legal terms. The applicable license version and redistribution credits remain to be verified.

License

Pending verification Modified from original

Attribution

Copernicus Atmosphere Monitoring Service (CAMS), ECMWF. Regional processing and regridding: AtmoSeq.

Used for

Aerosol optical depth, components and particulate-concentration model inputs

Notes

The ADS global atmospheric-composition forecast dataset is interpolated from 0.4° to 0.25° when enabled. The official dataset currently lists a CC-BY license. Its version, account-accepted terms and complete attribution remain to be verified; IFS/AIFS terms are not automatically applicable.

Attribution

数据来源：中国环境监测总站全国城市空气质量实时发布平台；区域插值与加工：象序临近。

Used for

Air-quality validation and regional PM2.5/AQI interpolation

Notes

The workflow reads hourly station snapshots and generates regional interpolated grids; its default switch is off. Station values are designated internal archives. Display, processing and commercial-use rights remain unverified. Interpolation neither removes upstream rights nor creates official regional observations.

License

Pending verification Modified from original

Attribution

Source: NASA AERONET and contributing site teams. Data selection and validation: AtmoSeq.

Used for

Level 1.5 multi-wavelength aerosol optical depth and sunset-model calibration

Notes

The code selects observations from sites in and around China through AERONET for internal validation; the default switch is off. Site-investigator credits, use conditions and redistribution scope remain unverified. General NASA policies do not replace dataset-specific requirements.

OGIMET; originating national meteorological organisations

License

Pending verification Modified from original

Attribution

SYNOP reports via OGIMET; originating meteorological organisations retain their respective rights. Parsing: AtmoSeq.

Used for

Surface cloud amount, type and base-height decoding for internal validation

Notes

Disabled by default in code. OGIMET is an access channel and does not replace the originating organizations’ rights. Bulk access, operational use and redistribution need verification; public access alone does not establish an open license.

Used for

Mean/maximum elevation and terrain-obstruction inputs for sunset calculations

Notes

Public GLO-30 tiles are aggregated into terrain grids; this entry applies when those files are configured and used, not to other restricted DEM products.
