Thermosphere Hough Mode Extensions (HMEs) for Ultra-Fast Kelvin Waves (UFKWs)

The scientific basis for the UFKW HME files contained here is described in Forbes et al. (2023). The directory "Hough-UV functions" contains solutions to Laplace's Tidal Equation for the s = -1 eastward-propagating first symmetric (Kelvin) modes with periods 2.0-5.0d (48hr-120hr), and a README file containing further information on the data files. The directory "UFKW output files" provides UFKW amplitudes and phases (UT hour of maximum at 0 longitude) of eastward, southward, and vertical winds (m/s), temperatures (K), density perturbations relative to mean, and geopotential height (m) as a function of height (z, every ~4 km) and latitude (deg, every 3 deg), corresponding to wave periods between 2.0d and 5.0d, and a README file containing further information on the data files. The data for each HME extend from pole to pole and from 0 to 400 km altitude. Forbes, J.M., Zhang, X., & Palo, S.E. (2023). UFKW propagation in the dissipative thermosphere.
