Lifting Condensation Level (LCL) Height implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Effect

Computation or source lookup only

Input and validation requirements

The specification does not define temperature units or validation behavior for Td greater than T, and an extreme but finite JavaScript input overflows to Infinity. A robust implementation should require compatible temperature units, flag negative LCL results, and handle numeric overflow explicitly.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

{
  "inputs": {
    "temperature": 25,
    "dew_point": 17,
    "temperature_unit": "°C",
    "output_unit": "m_and_ft"
  },
  "expected_outputs": {
    "lcl_height_m": 1000,
    "lcl_height_ft": 3280.84
  },
  "working": "T − Td = 25 − 17 = 8 °C. LCL = 125 × 8 = 1000 m. Feet = 1000 × 3.28084 = 3280.84 ft."
}
