Abstract
In this research, we convert the visual gradient of an iridescent wave cloud into a data-rich gradient of temperature and relative humidity, by linking the Kelvin Curve of homogeneous nucleation to the Fraunhoffer Diffraction and Babinet’s Principle-derived formula for angular coronal size. We analyze how compatible the parameters and assumptions of Fraunhoffer and Babinet are, and then isolating the parameters that can be observed without instrumentation. The final equation takes variables that can be visually approximated- order of interference, wavelength, and angular distance from the sun- into temperature and relative humidity.
