Description
Format these with the supplied referenceElevationMeters.
Atmospheric quantities distinguish temperature coordinates, pressure references, and moisture mass ratios. Specific humidity uses total moist-air mass, while a mixing ratio uses dry-air mass; those denominators must be explicit.
Format these with the supplied referenceElevationMeters.
When to use this tool
Use Station Pressure Reduction Metadata Label when you need one atmospheric data component under a specified reference and unit convention.
How to use the tool and how it works
- Enter stationId, pressureType, referenceElevationMeters. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read label. Use the output convention below.
Require nonempty stationId and pressureType station, sea-level, or altimeter. Format these with the supplied referenceElevationMeters.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| stationId | Station Id | Required. Text; maximum UTF-16 length 8192. |
| pressureType | Pressure Type | Required. Text; one of "station", "sea-level", "altimeter"; maximum UTF-16 length 8192. |
| referenceElevationMeters | Reference Elevation Meters | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| label | Formatted label for the supplied components under the convention above. | Required. Text; maximum UTF-16 length 8192. |

"input": {
"stationId": "STN1",

"referenceElevationMeters": 250
},
"output": {
"label": "STN1; pressure=station; reference=250 m"
}
}Limitations and assumptions
- This labels a pressure convention without converting pressure, applying a reduction formula, or verifying station metadata or aviation suitability.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Verify the complete meteorological definition and input measurements before combining the result with a model or observation series.
