If your sensors have an accuracy of ±0.1°C and ±10Pa, the uncertainty in n is approximately: --
Calculation based on root-sum-square (RSS) of partial derivatives.This engine implements the Ciddor (1996) standard for the refractive index of air, utilizing the Buck Equation for water vapor pressure. The temperature coefficient dn/dT is crucial for compensating laser distance measurements in industrial metrology.
