Paper on the impact of new satellite wind velocity data on hurricane forecasts published in Monthly Weather Review

Summary: The CYclone Global Navigation Satellite System (CYGNSS) was launched into space on December 15, 2016, to improve hurricane (tropical cyclone) forecasts by measuring wind speed on the ocean surface. Since the tropical cyclones mostly occur over oceans where other wind data are usually not available, the new observations can measure their wind speeds. This …

Paper on calculating and using wind speed and direction from the new NASA CYclone Global Navigation Satellite System (CYGNSS) released online in the Journal of Atmospheric and Oceanic Technology

Summary:  The NASA CYclone Global Navigation Satellite System (CYGNSS) measures wind speed, but not direction, at the ocean surface. To test the impact of new observations before such a satellite system is launched, observations like those from the satellite are created from a weather model. This study uses these “simulated” observations to learn how to …

HRD Seminar – Dr. Andrew Kren, CIMAS and AOML/HRD – 27 June 2018

Dr. Kren presented a seminar titled “Observing System Simulation Experiments (OSSEs) and Observing System Experiments (OSEs) to evaluate the impact of current and future observing systems in the NCEP GDAS”. ABSTRACT: Observing System Experiments (OSEs) test the impact of current observing system platforms on analyses and forecasts, while Observing System Simulation Experiments (OSSEs) can evaluate …

Paper on the potential impact of wind measurements from CYGNSS on forecasts published in Monthly Weather Review

Abstracts and recordings of  the 27 presentations and 9 posters AOML & HRD researchers presented (or were co-authors) at the 98th AMS Annual Meeting are available online from the AMS website: Presentations: Karina Apodaca, M. Zupanski, L. Cucurull, and M. Hu - Implementation of the GOES-16 GLM Lightning Assimilation into the NCEP/GSI System for Improved …

HRD Seminar – Dr. Sean PF Casey, CIMAS and AOML/HRD – 15 February 2018

Dr. Casey presented a seminar titled "Geostationary Hyper-Spectral Sounder (Geo-HSS) Constellation:  A Global Observing System Simulation Experiment (OSSE) Assessment". Abstract Observing System Simulation Experiments (OSSEs) can provide quantitative assessments of potential impacts of new observation sources, without the instrument actually being built in some cases. This presentation describes the set-up of global-scale OSSEs, from the …
