A dataset that the AOI or window misses (for example prism in Alaska) is skipped with a warning. Licenses differ: check each group’s license attribute before sharing a store.

Synoptic stations¶

Station reports from the Synoptic Data API. Requires a SYNOPTIC_TOKEN.

precip_accum (default) is staged as precipitation, a running total in mm. Other Synoptic variables, such as air_temp, keep their Synoptic names and units.
Every report is kept, as a CF ragged array. gaia_cli.stations.to_grid(ds) puts the reports on a regular hourly (or daily) grid, and to_dataframe(ds) gives one row per report.
License: set by each station network.

PRISM¶

PRISM AN81d daily grids, 800 m, EPSG:4269.

Variables: ppt (default, staged as precipitation, mm), tmin, tmax, tmean (degC).
A PRISM day D covers 12:00 UTC on D−1 to 12:00 UTC on D. The value is stamped D 00:00, and time_bounds gives the true period.
Read from a public cache of PRISM’s grids, browsable in STAC Browser. Recent grids are re-released by PRISM for about 6 months; each value records its prism_release (8 is final).
License: PRISM terms of use.

HRRR¶

NOAA High-Resolution Rapid Refresh analysis from dynamical.org, 3 km, Lambert Conformal Conic, hourly.

Variable: precipitation-surface (default, staged as precipitation in mm per hour), or any other in gaia stage hrrr --help.
Precipitation is hour-ending: the value at 13:00 fell between 12:00 and 13:00 UTC.
Wind components are grid-relative, not east/north.

NLCD¶

USGS Annual National Land Cover Database, 30 m, one year (--year, default 2021). Classes are integer codes with CF flag_values/flag_meanings. License: U.S. public domain.

DEM¶

`--product`	source	heights	coverage
`cop30` (default)	Copernicus GLO-30, surface model, 30 m	EGM2008	global
`usgs10m`	USGS 3DEP 1/3 arc-second, bare earth, 10 m	NAVD88	US

Heights are not converted between vertical datums. Each product is its own group, so one store can hold both.

Soil¶

`--product`	source	variables
`solus100` (default)	SOLUS100, 100 m, CC-BY-4.0	surface clay, sand, silt, bulk density, pH, CEC, and depth to bedrock
`statsgo`	STATSGO K-factor, 30 m from 1:250,000 polygons, public domain	`kffact`, soil erodibility

Burn severity¶

USDA Forest Service BAER soil burn severity maps, chosen by the AOI. Where several fires intersect it, choose one with --fire (part of its name) and --year. Classes: 1 unburned to very low, 2 low, 3 moderate, 4 high. Each fire keeps its own grid. License: U.S. public domain.
