JCSDA Seminar: Data assimilation for limited-area models in central Europe

Please join the Joint Center for Satellite Data Assimilation (JCSDA) in welcoming visiting speaker Benedikt Strajnar from the Slovenian Meteorological Service this Friday, October 18, 2019 from 1-2 PM in FL2-1001. Benedikt will be giving a talk entitled, "Data assimilation for limited-area models in central Europe." Please see the abstract below. 

Short abstract: The seminar will present current capabilities, challenges and developments of data assimilation in Slovenia and, more broadly, within the Regional Cooperation for Limited Area modeling in Central Europe (RC LACE). In all seven participating national meteorological services, Aire Limitee Adaption Dynamique INternational (ALADIN) numerical weather prediction model is run operationally at spatial resolution from 1 do 8 km. Countries use a common observation data hub and typically apply three-dimensional variational assimilation. The use of satellite radiances will be discussed, with some remarks related to the limited-area modeling (thinning, bias correction). Developments related to other in-situ and remote sensing observations like high-resolution aircraft and surface observations, radar and Global Navigation Satellite System-based ground observations will also be presented. These assimilation systems are expected to benefit from future Meteosat Third Generation (MTG) satellite observations of European Organization for Exploitation of Meteorological Satellites (EUMETSAT), especially the hyperspectral sounder.
