The radar measures the winds, waves and tides of the mesosphere and lower thermosphere. The radar design was optimised to make measurements of the variances, fluxes and variability of gravity waves by the use of pulse coding. The pre-t0-phase technique (see linked documentation for details) was employed to estimate meteor astronomical entry speeds and flexible modes of operation were designed into the system. The BLO site hosts complementary optical instruments including optical images and lidars.","keywords":"mesosphere, thermosphere, VHF radar","status":"completed","publicationState":"published","identifier_set":[],"observationCollection":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/27283/?format=json"],"parentProject":null,"subProject":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/113992/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/113993/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/113994/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/113995/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/113997/?format=json","https://catalogue.ceda.ac.uk/api/v2/rpis/113996/?format=json"]}
