ciddor equation for refractive index of air

Calculates the refractive index of air

You are now following this Submission

Accurate calculation for the refractive index of air can be used for metrology or optics. The function is vectorized and contains sub-functions for the required calculations of humidity as a mole fraction and the saturation vapour pressure. All inputs are validated to ensure they are within the valid range.
