The colorbar is in meters per second. The horizontal level is the terrain-following sigma level 0.154 and 0.206 which is on average near 156 hPa and 209 hPa respectively.
The full dataset of daily Kelvin waves on 43 terrain-following levels from 1 January 1980 until 31 December 2019 can be made available.
