One immutable weather observation. All measurement fields are optional and SI-only: celsius, hectopascal, meters/second, millimeters, W/m². Record key SHOULD be a TID derived from observedAt.
Record Key
tid
Timestamp-based ID
Properties
airQuality
object
Optional
Outdoor ambient air-quality mass concentrations, µg/m³. Derived indexes (AQI, EAQI, …) are intentionally not stored: they are jurisdiction- and time-window-specific and must be computed by consumers from the concentration series.
dewPoint
ref
net.atmowx.defs#quantity
Optional
Dew point, °C.
extra
array
of
union
Optional
Measurements not covered by core fields. Open union.
maxLength: 64 items
Known types:
observedAt
string
datetime
Required
Measurement time, UTC.
precipitation
object
Optional
No description available.
presentWeather
integer
Optional
WMO code table 4680 (present weather from automatic station).
minimum: 0maximum: 99pressureSeaLevel
ref
net.atmowx.defs#quantity
Optional
Mean-sea-level reduced pressure, hPa.
pressureStation

relativeHumidity
ref
net.atmowx.defs#quantity
Optional
Relative humidity, percent.
snowDepth

net.atmowx.defs#quantity
Optional
Millimeters.
soilMoisture
ref
net.atmowx.defs#quantity
Optional
Percent.
soilTemperature
ref
net.atmowx.defs#quantity

Required
AT-URI of the net.atmowx.station this reading came from.
temperature
ref

Optional
Air temperature, °C.
uvIndex
ref
net.atmowx.defs#quantity
Optional
UV index, dimensionless.
