August 11 - 14, 2015
3450 Mitchell Lane, Boulder, Colorado
GSI & EnKF - Starting Tuesday Morning on August 11 - 14, 2015
EnKF Only - Starting Thursday Afternoon on August 13 - 14, 2015
GSI knowledge is required for the EnKF Only Session
The combined Gridpoint Statistical Interpolation and Ensemble Kalman Filter (GSI/EnKF) Community Data Assimilation System Tutorial will be offered at the NCAR Foothills Laboratory, in Boulder, Colorado on August 11-14, 2015. This will be the sixth Community GSI tutorial, but the first time EnKF will be included.
GSI is the operational data assimilation (DA) system being used by various national operational and research centers, including NOAA and the National Aeronautics and Space Administration (NASA). It is traditionally a three-dimensional variational DA system and has been extended to run with advanced features, including the hybrid ensemble-variational data assimilation technique and the four dimensional EnVAR technique.
The EnKF system is a Monte-Carlo algorithm for data assimilation that uses an ensemble of short-term forecasts to estimate the background-error covariance in the Kalman Filter. The EnKF uses the observation operators in the GSI system to transform model variables to observed variables in observation space. Therefore, the types of observations available for use in the EnKF match those for the GSI. Currently this EnKF is running operationally as part of the GSI based hybrid data assimilation system for the National Centers for Environmental Prediction (NCEP) global applications.
The combined GSI/EnKF Community Tutorial will be held over the four days of August 11-14. The GSI/EnKF tutorial will consist of both lectures and hands-on practical exercises. The lecturers are invited from various GSI and EnKF development/support teams including NCEP/EMC, NASA/GMAO, NOAA/GSD, NCAR/MMM and DTC. The practical sessions will provide the necessary skills to run both the GSI and EnKF systems for both basic and advanced implementations. The tutorial will be tailored to the upcoming release code (GSI and EnKF) scheduled for June, 2015
The tutorial consists of a combination of classroom lectures and a hands on practical session. We offer a choice of two registration options:
Full GSI/EnKF Tutorial (4 days): $400 (includes lunch and refreshments)
EnKF Only Tutorial (1.5 days): $130 (includes lunch and refreshments)
There will be NO refunds for cancellations made on, or after 3 PM MT on Friday July 31th, 2015. Prior to the July 31th deadline, we will refund the registration fee, less $25.00 to cover administrative costs.
