NMFs used by MODES are eigensolutions of the linearized primitive equations in the terrain-following sigma coordinates and were derived by Kasahara and Puri (1981, Mon. Wea. Rev). The available data are three data sets (40 years), calculated from ERA5 reanalyses by modal filtering of certain wave components, here Kelvin waves (KW), Mixed Rossby-gravity waves (MRG) and Rossby wave n=1 (Rosn1). Near-realtime modal decompositions of ECMWF deterministic forecasts, using the same tool (MODES) as has been used for the generation of the dataset are under this URL: https://modes.cen.uni-hamburg.de/ Frank Sielmann University of Hamburg http://www.mi.uni-hamburg.de/ pointOfContact Prof. Nedjeljka Zagar University of Hamburg http://www.mi.uni-hamburg.de/ pointOfContact NetCDF CLICCS CLICCS A2 Kelvin waves MODES Rossby waves atmosphere tropical waves CC-BY-4.0: Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ eng; USA 0.0 358.5938 -88.9277 88.9277 standard 1980-01-01 2019-12-31 info:eu-repo/grantAgreement/DFG//390683824/DE//EXC 2037: Climate, Climatic Change, and Society (CLICCS) geopotential_height Geopotential is the sum of the specific gravitational potential energy relative to the geoid and the specific centripetal potential energy. Geopotential height is the geopotential divided by the standard acceleration due to gravity. It is numerically similar to the altitude (or geometric height) and not to the quantity with standard name height, which is relative to the surface. [CF-Standard Name]; unit: gpm eastward_wind "Eastward" indicates a vector component which is positive when directed eastward (negative westward). Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.)
