Lexicon reference

atmowx data lives in AT Protocol repositories as records described by five published lexicons in the net.atmowx.* namespace. Stations and observations are records that station owners publish to their own repos; the two query lexicons describe the AppView’s read API. The schemas below are rendered directly from the published lexicon documents — this page cannot drift from the schema. Fields marked * are required.

Concepts

Quantities: decimals as scaled integers

The lexicon data model has no floating-point type, so every numeric measurement is a quantity: an integer significand plus a power-of-ten scale, decimal = value × 10^scale. Values stay exact, and publishers must not report more precision than the sensor resolves.

{ "value": 186, "scale": -1 }   // 18.6 °C

SI units only

Records carry SI units exclusively: °C, hPa, m/s, mm, W/m², µg/m³. Unit conversion for display is the consumer’s job. Derived indexes (like AQI) are intentionally not stored — they are jurisdiction-specific and must be computed from the concentration series.

TID keys, immutable observations

Station and observation records use TID record keys. An observation’s key should be derived from observedAt, and observations are immutable once published.

Open unions

location.position and extra are open unions: values with types beyond the listed ones remain valid, and consumers must tolerate members they do not recognize.

Stations do not move

A station that physically relocates must be retired (status: retired) and a new station record created, so historical observations stay tied to the site where they were measured.

Schema resolution

The schemas are published, resolvable records — not just files in a repo. Each lexicon lives as a com.atproto.lexicon.schema record (record key = the NSID) in the authority repo did:plc:7ytchp6nym3ugtpx7ttilnur. NSID authority for net.atmowx.* is delegated via DNS:

$ dig +short TXT _lexicon.atmowx.net
"did=did:plc:7ytchp6nym3ugtpx7ttilnur"

Tooling that understands lexicon resolution can fetch any of the schemas below from that repo by NSID. The Raw lexicon schema blocks on this page show the exact published documents.

#quantity

A decimal number as a scaled integer: decimal = value * 10^scale. Publishers MUST NOT report more precision than the sensor resolves.

Field	Type	Description
`value`(required)	integer	Significand.
`scale`	integer	Power-of-ten exponent. Default 0.default 0

#location

Where a station is sited. Elevation is strongly recommended: pressure data is hard to interpret without it.

Field	Type	Description
`position`(required)	open union · community.lexicon.location.geo \| community.lexicon.location.hthree \| community.lexicon.location.address	The position, as a community location shape. Open union: additional shapes remain valid.
`geohash`	string	Denormalized geohash index hint. Precision is the owner's choice and doubles as a privacy knob.max 12 bytes
`elevation`	integer	Meters above mean sea level (whole meters).
`sensorHeight`	quantity	Sensor height above ground level, meters.

#measurement

An arbitrary measurement for parameters not covered by the core observation fields. Units MUST be SI.

net.atmowx.getStationHistoryquery

Time series for one station. bucket=raw returns individual readings (capped at 5000 points; narrow the range or coarsen the bucket on RangeTooLarge). hour/day buckets return UTC-aligned min/avg/max (sum for precipitation). No auth.

Parameters

Field	Type	Description
`station`(required)	string · at-uri	AT-URI of the net.atmowx.station record.
`from`(required)	string · datetime
`to`(required)	string · datetime
`bucket`	string	default "raw"`rawhourday`

Output (application/json)

Field	Type	Description
`station`(required)	string · at-uri
`bucket`(required)	string
`series`(required)	array · series

#series

One measured parameter's series. The parameter set is open: additional parameters may be served later without a schema change.

Field	Type	Description
`parameter`(required)	string	max 128 bytes`temperaturedewPointrelativeHumiditypressureSeaLevelwindSpeedwindGustwindDirectionprecipitationRateprecipitationDaysolarIrradianceuvIndexpm1pm25pm10ozoneno2so2co`
`unit`(required)	string	SI unit name, e.g. celsius, hectopascal, metersPerSecond, millimeters, percent, wattsPerSquareMeter.max 64 bytes
`points`(required)	array · point

#point

Field	Type	Description
`time`(required)	string · datetime	Reading time (raw) or UTC bucket start (hour/day).
`value`	quantity	Present for bucket=raw.
`min`	quantity
`avg`	quantity
`max`	quantity
`sum`	quantity	Precipitation buckets report sum instead of min/avg/max.

Errors

StationNotFound — No indexed station with that AT-URI.
RangeTooLarge — raw bucket over 5000 points; narrow the range or use hour/day.
InvalidBucket — bucket must be raw, hour, or day.
