Provide supports for Community Researchers to Use Operational Gridpoint Statistical Interpolation (GSI) System
Over the last five years, the DTC has made a significant progress in transitioning the National Centers for Environmental Prediction (NCEP) operational data assimilation system, Gridpoint Statistical Interpolation (GSI), to a community resource. The DTC has hosted four Community GSI tutorials and released five versions of the community GSI system with a corresponding User's Guide. The DTC has built and continues to maintain a community GSI User's Webpage to provide GSI code, documentation, and on-line tutorials for the research community. The DTC staff has been providing support to the GSI users through the GSI help desk since the release of version 1 of the community code in 2009.
With the significant effort of DTC and NCEP's Environmental Modeling Center (EMC) data assimilation group, the community GSI has been used in many research and operational areas by hundreds of users across the world. To promote the use of the community GSI for broader users in different areas, we will give a detailed introduction to the community GSI system and supports in this talk.
