Topic : Development and Application of Land Data Assimilation Systems (LDAS) in NCEP Operations
Research Scientist,Environmental Modeling Center (EMC) National Oceanic and Atmospheric Administration, USA Host : Prof. Qingyun Duan Abstract: The NCEP/EMC LDAS team has collaborated with its partners in developing two LDAS systems: the North American Land Data Assimilation System (NLDAS) and the Global Land Data Assimilation System (GLDAS). The purpose of NLDAS is to provide initial states to regional numerical models to enhance regional weather and climate prediction skills and to support the U.S. National Integrated Drought Information System (NIDIS) such as U.S. drought monitor (drought.gov). We suggest development directions of the next generation NLDAS at NCEP. The purpose of GLDAS is to provide optimal initial states to the NCEP Climate Forecast System (CFS) to improve global climate simulation and prediction and generate new hydrometeorological reanalysis products to support users. GLDAS, a semi-coupled system, uses the NCEP CFS global reanalysis products and hybrid precipitation (i.e., gauge, satellite, model) as surface forcing to run the NCEP Noah land surface model in the operational CFS. GLDAS is included as a part of the recent CFS reanalysis . Time: 14:30-16:30 PM, 23rd Jun(Thursday), 2011 Venue: GCESS Simulation Hall,1st floor,Sci&Tech Building Welcome to Participate! 相关附件： |
