Application of Multiple Wind Retrieval Algorithms in Nowcasting
Atmosphere, 2015 Multiple wind retrieval algorithms are performed to retrieve wind fields, based on which radar reflectivity is extrapolated to implement nowcasting. The frequently used nowcasting algorithm COTREC (continuity of tracking radar echo by correlation), based

Determining Number of Factors in Dynamic Factor Models Contributing to GDP Nowcasting
Mathematics, 2021 Real-time nowcasting is a process to assess current-quarter GDP from timely released economic and financial series before the figure is disseminated in order to catch the overall macroeconomic conditions in real time. In economic data nowcasting, dynamic
