Dates/Location:

11-14 July, 2017 at the NOAA Center for Weather and Climate Prediction (NCWCP) conference center in College Park, MD.

About

The combined Gridpoint Statistical Interpolation (GSI) and Ensemble Kalman Filter (EnKF) Data Assimilation (DA) System Community Tutorial is co-hosted by the Developmental Testbed Center (DTC), the National Centers for Environmental Prediction (NCEP) Environmental Modeling Center (EMC), and the Joint Center for Satellite Data Assimilation (JCSDA). Information regarding the GSI and EnKF systems can be found at the Community GSI User Homepage and the EnKF User Homepage .

The tutorial consists of three days of lectures (Tuesday-Thursday) and four hands-on practical sessions (Tuesday-Friday) where the Friday practical session is optional. Please refer to the agenda for more details. The invited speakers are from the primary GSI and EnKF development teams, including DA experts from NOAA, JCSDA, the National Aeronautics and Space Administration (NASA), the National Center for Atmospheric Research (NCAR), University of Maryland and the DTC. The practical sessions will provide the essential skills to run the GSI/EnKF system with basic and advanced implementations.

Requirements

Basic knowledge of numerical weather prediction (NWP) models (e.g., WRF, GFS) and DA, as well as essential skills in Fortran and Unix, are required for the class.

For practical sessions, participants should bring a laptop computer with a ssh client with x11 forwarding. The laptop also needs a USB port for the token (provided) to access NCAR's High Performance Computing.

Available Spaces

Tutorial lecture and practical sessions: 40 on a first-come first-served basis, due to the constraints of physical space and computers

Tutorial lecture only: No limits
