During 2015 and 2016, NOAA conducted three field campaigns using the NASA Global Hawk autonomous aircraft outfitted with GPS dropwindsondes and remote sensors. The Sensing Hazards with Operational Unmanned Technology (SHOUT) project evaluated the potential ability of this high-altitude aircraft to collect novel observations to improve forecasts of high-impact weather events including hurricanes. The experiment also examined the effectiveness of employing new technology of this type. A new article to be published in the Bulletin of the American Meteorological Society, led by ESRL PSD with multiple NOAA and joint institute co-authors, provides a an overview of SHOUT and summarize the various missions flown over the two-year campaign, the observations collected and their application, and the results of a diverse set of studies evaluating the impact of the data on multiple operational forecast systems.

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.

This week collaboration between ESRL PSD researchers Gijs de Boer (CIRES), Janet IntrieriChristopher Cox (CIRES), and Jackson Osborn (CIRES), and the University of Alaska - Fairbanks Alaska Center for Unmanned Aircraft Systems Integration (ACUASI) flight team resulted in extended operation of the SeaHunter unmanned aircraft system over the Arctic’s Beaufort Sea.  The aircraft, carrying the miniFlux payload developed jointly by NOAA PSD and the University of Colorado, set out on a mission from Kuparuk airport to 72.5⁰ N latitude to make important measurements of atmospheric winds and thermodynamic properties as well as map sea ice concentration and sea surface temperature.  These observations support development of understanding of the roles of the ocean and atmosphere in fall sea ice development.  This airborne activity, in conjunction with oceanic assets deployed as part of the U.S. Office of Naval Research Departmental Research Initiative Stratified Ocean Dynamics of the Arctic (SODA), (SODA), will help to shed light on upper oceanic stratification and its connection to winds and sea ice cover. This activity, supported by the NOAA UAS program office and the National Science Foundation, is continuing over the next two weeks as the sea ice continues its seasonal march towards the Alaskan coastline.
