Why do a science transit?
DOE LASIC campaign: deployment of mobile ARM facility to Ascension (June 2016 – Oct 2017) Met Office enhanced surface site at St Helena (with cloud radar from University of Miami) Opportunity to obtain far-field measurements Discuss ideas for flight sorties this afternoon
4
LASIC AMF site scanning radar boundary-layer RHIs towards documenting cloud vertical structure ~200 deg view. est. 5 km range at 1.5 deg elevation hits cloud base
