Overview

The 5th NCEP Ensemble User Workshop will be held at a hotel near Washington DC in Maryland during the period May 10-12, 2011. The purpose of this workshop is to bring together experts and users involved in the generation and use of NCEP ensembles, to review progress on the generation and use of operational products since our last meeting in May 2008, and to discuss plans for future efforts and collaborations. The main goal of the workshop is to support NWS in its transition from single value to probabilistic forecasting. The ultimate goal is to convey forecast uncertainty in a user relevant form. Collaborative efforts on the national (NUOPC, DTC) and international (NAEFS, GIFS/TIGGE) scale will also be discussed. The workshop is organized by the NCEP Environmental Modeling Center jointly with the Developmental Testbed Center (DTC) Ensemble Testbed (DET) whose goal is to facilitate the testing and transition of newly developed methods into operations, with support from the Office of Science and Technology (OST) of NWS.

The proposed topics will include:
    1. NCEP operational ensemble systems;
    2. NCEP generated ensemble products;
    3. NWS ensemble based probabilistic products (or guidance);
    4. NCEP service centers’ reviews and future requests;
    5. NWS regions and WFO/RFC reviews and requests;
    6. National research/development community, private sector, DET, NUOPC reviews;
    7. International developers/users reviews (including NAEFS, GIFS/TIGGE);
    8. Ensemble data and product distribution, access and demonstration;
    9. Working group discussions
