Other aircraft instruments are required to provide “truth” and provide closure measurements.\r\n-To obtain microwave, submillimetre, infrared and visible aircraft data simultaneously with satellite overpasses (e.g. A-train, METOP).\r\n-To overfly ground based sites in cirrus conditions and obtain submillimetre and in-situ cirrus measurements.\r\n\r\n \r\n2)Cold Air Outbreak\r\n-To investigate processes controlling the transition between stratiform and cellular cloud structure in cold-air outbreak flows, including:\r\n-Surface fluxes of heat and moisture\r\n-Boundary-layer structure and flux profiles\r\n-Microphysical and precipitation processes, in particular ice formation and growth\r\n\r\n","keywords":"cosmics","status":"completed","publicationState":"published","identifier_set":["https://catalogue.ceda.ac.uk/api/v2/identifiers/9052/?format=json"],"observationCollection":["https://catalogue.ceda.ac.uk/api/v2/observationcollections/16532/?format=json"],"parentProject":null,"subProject":[],"responsiblepartyinfo_set":["https://catalogue.ceda.ac.uk/api/v2/rpis/54509/?format=json"]}
