Supported with UAS Program Office funding, a team from the University of Colorado Boulder will deploy the RAAVEN sUAS from Barbados between 19 January and 17 February 2020. Launch and retrieval will occur from the shore at a field and the adjacent beach in Morgan Lewis, Barbados.  RAAVEN miniFlux measurements can directly contribute to advancing our scientific understanding relevant to NOAA forecasting efforts across weather and climate scales. Specifically, information on the vertical distribution of dynamic (momentum) and thermodynamic fields (heat fluxes), spatial and temporal variation of PBL height, formation and maintenance of tropical clouds, and ABL stability can be used to evaluate boundary layer and cloud parameterizations. This to examine and better understand the physical processes supporting the organization of tropical clouds and to provide guidance on model physics development. Improving model physics is one of the major goals articulated in NOAA’s Unified Forecast System (UFS) Goals and Priorities document.
