The mesosphere influences, and is influenced by, in-situ and external effects such as atmospheric waves and tides (upward) and space weather effects (downward); and is strongly coupled to the lower edge of the ionosphere and the other atmospheric regions. A sound scientific understanding of the drivers of variability in the mesosphere is therefore needed in order to advance modelling of the whole atmosphere as a coupled system.\r\n\r\nThis project was led by British Antarctic Survey (BAS) scientists under Natural Environment Research Council (NERC) project MesoS2D (grant reference: NE/V018426/1).","keywords":"atmospheric tides, mesosphere, CESM, WACCM, NE/V018426/1","status":"completed","publicationState":"published","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/13853/?format=json"],"observationCollection":[],"parentProject":null,"subProject":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/219426/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219427/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/219428/?format=json"]}
