Virga Shaft Evaporation Height Lookup
Observed virga evaporation height vs independently matched humidity/profile reference, not rainfall-at-ground forecast. Exact caller verified numeric reference; signed deviations retained. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.
Description
Virga is precipitation observed aloft that does not persist to the ground along the observed shaft.
Virga is precipitation observed aloft that does not persist to the ground along the observed shaft.1
This audit retrieves your exact numeric reference and retains the signed observed-minus-reference difference.
When to use Virga Shaft Evaporation Height Lookup
Use this tool to compare an observation with its exact numeric reference. Match the observation method, units, averaging period and independently established reference.
How to use Virga Shaft Evaporation Height Lookup and understand its results
- Match the observation method, units, averaging period and independently established reference.
- Enter callerVerifiedVirgaEvaporationHeightKeys, callerVerifiedVirgaEvaporationHeightValues, queryVirgaEvaporationHeightKey, observedVirgaEvaporationHeightValue, using the field meanings and rules below, then run the tool.
- Read callerReferenceValue, signedObservedMinusReference. Inspect nested result fields where present, and review unknown records separately from known matches.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerVerifiedVirgaEvaporationHeightKeys | Caller verified virga evaporation height keys | list of string | Required |
| callerVerifiedVirgaEvaporationHeightValues | Caller verified virga evaporation height values | list of number | Required |
| queryVirgaEvaporationHeightKey | Query virga evaporation height key; use the exact reference token or coordinate domain stated below | string | Required |
| observedVirgaEvaporationHeightValue | Observed virga evaporation height value | number | Required |
Supply nonempty aligned unique nonblank reference keys and finite reference numbers. Query one exact existing key and provide a finite observation in the same units. Return the matched number and observed-minus-reference; signed inputs are accepted and no special physical range is inferred. Unknown keys fail.
reference=values[indexOf(keys,query)]; difference=observed−reference Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| callerReferenceValue | Caller reference value | number |
| signedObservedMinusReference | Signed observed minus reference; preserve the subtraction order and sign defined in the mechanics | number |

}Limitations and assumptions
The observations and reference conditions must be independently established. This result is a record summary or stated model screen, not an official warning or a validated event forecast. Reference records and their claimed verification are supplied by the caller; the tool does not retrieve or verify them.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.
Alternative or Complementary methods

For a complementary comparison, use Snow To Liquid Ratio Climatological Lookup: The snow-to-liquid ratio compares snowfall depth with its melted water equivalent on a matched basis.
