Shade Cloth Percent Selection Lookup

Screen actual shade cloth candidates under matched measured transmission and caller DLI band, preserving no/multiple matches; no nominal shade-percent inference or cooling/crop recommendation.

Description

Shade candidates can be compared using matched measured light transmission.

Shade candidates can be compared using matched measured light transmission. Desired DLI must come from the caller’s crop/context.^[1]

Enter aligned nonempty unique IDs/transmissions0–1, nonnegative incident DLI and ordered nonnegative two-value range. Return all modeled values and every compatible ID.

When to use Shade Cloth Percent Selection Lookup

Use Shade Cloth Percent Selection Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. No match or multiple matches is valid. Nominal shade percentage, cooling and crop recommendation are not inferred.

Prepare measured container, labor, environmental or inventory records and independently verified stage limits requested. Keep units, temperature conditions and dates consistent.

How to use Shade Cloth Percent Selection Lookup and understand its results

Prepare measured container, labor, environmental or inventory records and independently verified stage limits requested. Keep units, temperature conditions and dates consistent.
Enter callerShadeClothIds, matchedMeasuredTransmissionFractions, incidentDli, callerAcceptableDliRange using the field table and calculation rules, then run the tool.
Read modeledClothDli, callerCompatibleShadeClothIds. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
callerShadeClothIds	Caller shade cloth ids	list of string	Required
matchedMeasuredTransmissionFractions	Matched measured transmission fractions	list of number	Required
incidentDli	Incident dli	number	Required
callerAcceptableDliRange	Caller acceptable dli range	list of number	Required

Enter aligned nonempty unique IDs/transmissions0–1, nonnegative incident DLI and ordered nonnegative two-value range. Return all modeled values and every compatible ID.

clothDLI=incidentDLI×transmission; compatible=lower≤DLI≤upper

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
modeledClothDli	Modeled cloth dli	list of number
callerCompatibleShadeClothIds	Caller compatible shade cloth ids	list of string

Limitations and assumptions

No match or multiple matches is valid. Nominal shade percentage, cooling and crop recommendation are not inferred.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Source Water EC Threshold Lookup: Source-water EC screening needs a verified crop-stage ceiling and known measurements. Missing EC observations are not passing values. For a complementary task, use Ridge Vent Opening Ratio Checker: Vent opening area is reduced by observed obstruction before comparison with floor area. Area ratio alone does not establish airflow.
