Description
Return one layer's pressure-thickness share.
Atmospheric state formulas depend on absolute temperature, pressure reference, water mass/volume bases and layer assumptions. Local adiabatic, hydrostatic or precipitation terms can illustrate a supplied model without reconstructing an actual profile, validating an instrument or predicting weather hazards.
Return one layer's pressure-thickness share.
When to use this tool
Use Pressure Weighted Layer Share when checking the stated atmospheric pressure, temperature, humidity or water-basis term.
How to use the tool and how it works
- Enter layerPressureThickness, totalPressureThickness. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read share. Use the output convention below.
Return one layer's pressure-thickness share. Require positive totalPressureThickness and layer thickness within [0,total]; share = layer/total.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| layerPressureThickness | Layer Pressure Thickness | Required. Finite number; minimum 0. |
| totalPressureThickness | Total Pressure Thickness | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| share | Dimensionless numerator/denominator ratio under the explicit basis above. | Required. Finite number. |

}Limitations and assumptions
- This is a supplied hydrostatic weighting basis, not an actual column integral or independently measured mass fraction.
- 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
Use verified observations and an appropriate complete thermodynamic/profile analysis with explicit units, references and moisture assumptions for meteorological conclusions.
