An Overview of Progresses in LAPS and Prospective Applications in Real Time Data Service

The spatial-temporal density of observation data is greatly improved with steady developments of meteorological observation system in our country, while the spatial and temporal representativeness of each data source is very different. Combining multi-source data to carry out fusion analysis is one of the research hotspots at home and abroad. The LAPS, local analysis and forecasting system developed by NOAA, is used to analyze three-dimensional and high-resolution grid data with reference to the reliability of each data source. LAPS system has the characteristics of open source code, complete analysis algorithm and flexible framework, which can be adjusted quickly to adapt to the domestic observation environment, and leads to enormous research and applications. This paper reviews the research progress of LAPS fusion system, especially focuses on the application to real time data service.
