100-Hour Moisture Class Lookup
Audit independently verified100-hour fuel moisture class reference. Audit caller independently verified matched reference against actual observation, not a fabricated specification. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.
Description
A hundred-hour fuel-moisture reference uses a particular fuel class and observation convention.
A hundred-hour fuel-moisture reference uses a particular fuel class and observation convention.1
A numerical lookup does not measure fuel moisture or determine the current ignition conditions of a forest. Use this tool to compare an observation with an exact caller-supplied numeric reference.
When to use 100-Hour Moisture Class Lookup
Use this tool to compare an observation with an exact caller-supplied numeric reference. Establish the species/site, survey protocol, units, sampled area or exposure, and the independently chosen reference or model.
How to use 100-Hour Moisture Class Lookup and understand its results
- Establish the species/site, survey protocol, units, sampled area or exposure, and the independently chosen reference or model.
- Enter callerHundredHourMoistureIds, callerHundredHourMoistureValues, queryHundredHourMoistureId, observedHundredHourMoistureValue, using the field meanings and rules below, then run the tool.
- Read callerMatchedHundredHourMoistureValue, signedObservedMinusHundredHourMoistureReference. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerHundredHourMoistureIds | Caller hundred hour moisture ids | list of string | Required |
| callerHundredHourMoistureValues | Caller hundred hour moisture values | list of number | Required |
| queryHundredHourMoistureId | Query hundred hour moisture id | string | Required |
| observedHundredHourMoistureValue | Observed hundred hour moisture value | number | Required |
Enter nonempty aligned caller reference IDs and numeric reference values, an exact query ID and an observed value on the same unit and protocol basis. Reference values and the observation must be nonnegative; they need not be integers. IDs must be unique and nonblank, with at most 128 UTF-16 units each. The implementation uses case-sensitive exact matching without trimming, returns the matched reference value and subtracts it from the observation. An absent query or duplicate key fails. No regional dataset is installed, retrieved or authenticated.
reference=values[indexOfExact(queryId,ids)]; signedDifference=observed−reference Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| callerMatchedHundredHourMoistureValue | Caller Matched Hundred Hour Moisture Value; follow the units, sign, ordering and evidence convention stated above | number |
| signedObservedMinusHundredHourMoistureReference | Signed Observed Minus Hundred Hour Moisture Reference; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
The numerical reference, unit basis and observation come from the caller. No authoritative regional table, standard edition, calibration or management rule is installed, retrieved or verified.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
