GOES ABI CONUS imagery
Available since v0.8 as noaa:goes-abi. The initial product is
single-channel CONUS Cloud and Moisture Imagery, ABI-L2-CMIPC. Files are
NetCDF4/HDF5 scenes from the anonymous noaa-goes16, noaa-goes17,
noaa-goes18, and noaa-goes19 buckets. No AWS credentials or SDK are needed.
Other ABI products and scan sectors remain unsupported.
Require satellite (16, 17, 18, or 19), channel (1–16, also C01–C16),
and both timestamps. product defaults to ABI-L2-CMIPC and rejects any other
value. Unknown parameters, text/geographic constraints, and variables are rejected:
channels select distinct whole files; the server cannot crop these scenes or
select variables within them. temporal_subset means selecting archived scans.
The adapter lists hourly ABI-L2-CMIPC/YYYY/DDD/HH/ prefixes, follows S3
continuation tokens, and selects scans whose start times fall in the inclusive
UTC query interval. It does not select a scan that started before the interval
merely because the scan overlaps it. Filename start/end stamps have tenths-of-a-
second precision; asset metadata retains both bounds and the listed byte size.
Naive dates/times mean UTC; a date-only end is midnight at the start of that day.
Use a short interval to limit the number of whole-scene downloads.
For example, fetch one small shortwave-infrared scene (~255 kB):
uv run usdata fetch noaa:goes-abi \
--start 2024-05-06T12:01:18.1Z --end 2024-05-06T12:01:18.1Z \
-p satellite=18 -p channel=6
Channel 6 is reflected solar imagery and this example is mostly dark; it is chosen to keep the live fetch/restore check small. For thermal imagery, channel 13 scenes are roughly 4 MB in the verified sample. CMI represents reflectance for reflective bands or brightness temperature for infrared bands; consult the file's units and data-quality flags before analysis. The adapter preserves raw bytes and does not project, mask, or reinterpret imagery.
NOAA's product documentation
identifies CMIP channels, scan modes, and satellite coverage. The
NODD registry documents public cloud
access. Satellite availability varies by date and outages; no East/West alias
is inferred from a historical query. The catalog's start is the initial public
GOES-16 date, not a claim that every satellite was operating then. Listing
ABI-L2-CMIPC/2017/ with max-keys=1 confirmed the first scene at
2017-02-28T00:02:50.4Z. The bucket also has placeholder year-2000 test scenes;
the adapter excludes these by limiting selection to the public observation era
and rejecting intervals entirely before 2017-02-28.
