Notes. The eddy diffusion profile “K12 and K13” uses the coefficients below 47 km from Krasnopolsky (2012) and above 47 km from Krasnopolsky (2013). For the “K81 and K07” eddy diffusion profile coefficients below 47 km are taken from Krasnopolsky (2007) and above 47 km from Krasnopolsky & Parshev (1981).
