The Next Generation Global Prediction System (NGGPS) Project is an NWS initiative for designing/developing/implementing a non-hydrostatic global modeling system into operations with the goal of providing world's best global operational forecast guidance. Other objectives include accelerating development of advanced physics and data assimilation techniques and position NWS for next generation high performance computing. The Dycore Test Group (DTG) was established with a dedicated team of scientists comprising of various candidate modeling groups and three independent consultants for making recommendations for the selection of non-hydrostatic dynamic core. This presentation will summarize the findings of various tests conducted by DTG and it's assessment of results obtained thus far, and next steps associated with the decision making process.
