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 …

HRD Seminar – Scott B. Sieron, Pennsylvania State University – 12 February 2018

Scott presented a seminar titled  “Mesoscale tropical cyclone model EnKF data assimilation of all-sky satellite radiances: advancing from IR to microwave”. Abstract Development with the WRF tropical cyclone configuration and EnKF data assimilation system at Penn State is ongoing towards supporting the direct assimilation of top-of-atmosphere microwave emission observations in all sky conditions. These observations relate …

Paper on a way to initialize idealized hurricane models published in the Journal of Advances in Modeling Earth Systems

Computer models developed to forecast the weather need to know what is currently happening in the atmosphere and in the ocean, what we call “initial conditions,” each time the model starts. The process of making these initial conditions is known as “initialization.” This study is about a new initialization method for both the atmosphere and …
