Study on using hard-to-obtain observations from uncrewed aircraft in Hurricane Maria to improve analyses and forecasts published in Monthly Weather Review
For the first time, near-surface observations obtained by small Uncrewed Aircraft Systems (or drones) in a major hurricane (Hurricane Maria of 2017) were utilized in a state-of-the-art computer. Such observations are impossible to obtain using regular hurricane hunter aircraft. Furthermore, a new technique to identify and eliminate observations that may not be useful in improving analyses or … Continue reading Study on using hard-to-obtain observations from uncrewed aircraft in Hurricane Maria to improve analyses and forecasts published in Monthly Weather Review

HRD Seminar – Dr. Altug Aksoy (CIMAS/HRD) – 3 March 2020
Dr. Aksoy presented a seminar titled “Assimilation of Coyote UAS Observations in Hurricane Maria (2017): Optimization of Data Impact”. ABSTRACT The Coyote is a low-altitude small uncrewed aircraft system (sUAS) that is air-launched from the NOAA WP-3D (P-3) hurricane hunter aircraft through its existing standard A-size sonobuoy launch capability. Its meteorological sensors directly measure temperature, … Continue reading HRD Seminar – Dr. Altug Aksoy (CIMAS/HRD) – 3 March 2020
