Solar Constant W/m² Lookup

Independently verified measurement interval/reference-distance total-solar-irradiance record, not universal immutable solar constant. Exact independently verified context/edition key; not embedded or live reference data. Model only, not an ephemeris, measured stellar identity or observational guarantee.

Description

Solar irradiance depends on distance, measurement period and the stated quantity.

Solar irradiance depends on distance, measurement period and the stated quantity.^[1]

A reference notice avoids treating one historical value as a live universal constant. Use Solar Constant W/m² Lookup to retrieve an exact caller-supplied reference entry.

When to use Solar Constant W/m² Lookup

Use Solar Constant W/m² Lookup to retrieve an exact caller-supplied reference entry. Choose an independently reviewed reference for the exact historical, cultural or technical context, then supply its keys and texts.

How to use Solar Constant W/m² Lookup and understand its results

Choose an independently reviewed reference for the exact historical, cultural or technical context, then supply its keys and texts.
Enter Caller verified solar irradiance keys, Caller verified solar irradiance notices, Query solar irradiance key using the field table and validation rules below, then run the tool.
Read Matched caller notice; interpret the units, signs, ordering and unknown-value placeholders described below.
Correct reported input errors and rerun. Apply successful results according to their specific meanings and check the assumptions before using them in a decision.

Input field	Meaning	Value type	Requirement
callerVerifiedSolarIrradianceKeys	Caller verified solar irradiance keys	array of string	Required; constraints below
callerVerifiedSolarIrradianceNotices	Caller verified solar irradiance notices	array of string	Required; constraints below
querySolarIrradianceKey	Query solar irradiance key	string	Required; constraints below

Provide aligned, nonempty arrays of reference keys and independently verified notices, then enter the exact query key. Keys must be unique, nonblank and at most 128 UTF-16 code units long; notices must be nonblank. Matching is case sensitive and does not trim the query or returned text. The matching notice is returned unchanged; an unknown key is an input error. The reference contents and their applicability are supplied by the caller; the tool does not retrieve external records or verify source authority.

matched reference = suppliedTexts[indexOfExactQueryKey(suppliedKeys)]

Use the field order, units and branch conditions described above.

Output field	Meaning	Value type
matchedCallerNotice	Exact caller-supplied notice, unchanged and unverified.	string

Limitations and assumptions

A reference notice avoids treating one historical value as a live universal constant. Apply the exact scope and assumptions explained above.

All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse arrays fail validation. Domain-specific bounds, alignments and supported tokens are explained above; extremely large inputs or outputs can also be rejected. Input errors differ from successful false results, empty match lists and unknown-evidence placeholders.
