Description
Combine supplied dry/wet refractivity components and a wet share.
Atmospheric scalar terms require explicit averaging, spectral, geometric and propagation conventions. One fluctuation product is not a time-averaged flux, a squared deviation is not a full scintillation index, and a Nyquist interval does not de-alias radar velocity. Layer terms require compatible units and model assumptions.
Combine supplied dry/wet refractivity components and a wet share.
When to use this tool
Use Refractivity Dry Wet Component Pair when you already have dryRefractivity, wetRefractivity and need to combine supplied dry/wet refractivity components and a wet share.
How to use the tool and how it works
- Enter dryRefractivity, wetRefractivity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read totalRefractivity, wetFraction. Use the output convention below.
Require components>=0 and their sum>0; return sum and wet/sum.1

| wetRefractivity | Wet Refractivity | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| totalRefractivity | Total Refractivity | Required. Finite number. |
| wetFraction | Wet Fraction | Required. Finite number. |

}Limitations and assumptions
- Definitions and reference conditions must match. A nonfinite total is rejected; this does not retrieve gas state, humidity or refractive index from observations.
- 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 the complete measurement and physical retrieval model. Include calibration, averaging, source geometry, spectral response and relevant transfer or flow effects when local weights and signal factors cannot establish the desired atmospheric quantity.
