Deployment and Operation of the RAAVEN small Unmanned Aerial System (sUAS) in Support of NOAA Science during ATOMIC

UAS News /

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.

Surveying Antarctic Predators to Inform Fisheries Management

UAS News /

NOAA Fisheries’ Antarctic Ecosystem Research Division (AERD) studies and monitors several species of seals and penguins that are indicators of the health of the regional fishery for Antarctic krill. Krill are the focus of an expanding international fishery in the Antarctic, but are also a fundamental food source for the region’s fish, marine mammals, and birds. Accurate census counts and measurements of body condition are fundamental to seal and penguin population management, but can be difficult to obtain in remote polar environments. Funding from the UAS Program Office partially supports said studies.

(L-R): Ice Jam Flooding at Galena

Building an Operational Program for Small UAS for Flood Mapping and Routine Equipment Inspection at NWS Alaska

UAS News /

In Alaska, flooding is the most frequent cause of state disaster declarations. Ice jam floods during spring break-up have devastated many communities along waterways in the large Yukon and Kuskokwim River basins over the past century. Snowmelt and heavy precipitation can cause flooding in the spring and summer time. Alaska also faces frequent impacts from the outbursts of glacially dammed lakes. For many years, the Alaska-Pacific River Forecast Center (APRFC) has depended on partners to help monitor flood conditions in remote communities on the ground or in small aircraft. Building in-house capabilities to deploy small Unmanned Aerial Systems, helps bring cutting edge data collection to the decision-support services at the National Weather Service.
