Great Lapse Rate / Adiabatic Cooling 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.

Input and validation requirements

The extreme altitude input produces -Infinity through JavaScript floating-point overflow instead of a rejected or physically meaningful temperature. The signed-altitude probe also exposes a potentially severe convention-dependent result.

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": {
    "starting_temp_C": 12,
    "altitude_change": 1500,
    "altitude_unit": "m",
    "mode": "dry"
  },
  "expected_outputs": {
    "resulting_temp_C": -2.7
  },
  "working": "Convert altitude: 1500 m ÷ 1000 = 1.5 km. Cooling = 9.8 °C/km × 1.5 km = 14.7 °C. Resulting temperature = 12 °C − 14.7 °C = −2.7 °C."
