Description
Return dryBulb-wetBulb as depression, wetBulb-referenceWetBulb as referenceGap, and physicalOrder for wetBulb no greater than dryBulb.
Weather measurements depend on a common temperature scale, clock, or reference convention. A numeric consistency comparison can expose a difference without establishing which observation is accurate or predicting the weather.
Return dryBulb-wetBulb as depression, wetBulb-referenceWetBulb as referenceGap, and physicalOrder for wetBulb no greater than dryBulb.
When to use this tool
Use Wetbulb Precipitation Reference Temperature Gap when you need a supplied weather-reference difference or consistency flag.
How to use the tool and how it works
- Enter wetBulb, dryBulb, referenceWetBulb. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read depression, referenceGap, physicalOrder. Inspect physicalOrder before interpreting the associated values.

}Limitations and assumptions
- Temperatures share one scale; a false order flag is diagnostic and no humidity, precipitation phase, sensor correction, or weather forecast is inferred.
- 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
