2013 Joint DTC-EMC-JCSDA GSI Tutorial and Workshop

The Gridpoint Statistical Interpolation (GSI) Data Assimilation System Community Tutorial (August 5-7, 2013) and Workshop (August 8, 2013) will be offered at the NOAA Center for Weather and Climate Prediction (NCWCP) in College Park, MD. This marks the third annual GSI Tutorial and the second GSI Workshop since the GSI became a community model in 2009. It will be the first time for the National Centers for Environmental Prediction (NCEP) Environmental Modeling Center (EMC) and the Joint Center for Satellite Data Assimilation (JCSDA) to co-host these two events with the Developmental Testbed Center (DTC) on-site at NOAA, where the primary GSI developers are located.

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 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 DA framework.

The GSI Tutorial consists of both lectures and hands-on practical sessions. The invited speakers are from the primary GSI development teams, including the DA experts working at and with NOAA, JCSDA, NASA, the National Center for Atmospheric Research (NCAR), and the DTC. The practical sessions will provide essential skills to run GSI system with basic and advanced implementations.

The GSI Workshop will be a one-day event, audience open to all, with the speakers invited to talk only about the GSI and other related data assimilation techniques, system development, and research. The workshop is geared for both beginner and advanced data assimilation users, and is intended for users to share their experience on data assimilation efforts. Participants will have the option to remotely access the workshop.

Requirements

Basic knowledge of atmospheric science and numerical modeling, as well as Fortran and Unix, is required for the class. Some input data generated from the Global Forecast System (GFS) and Weather Research Forecast model (WRF) will be used. The hands on tutorial will not provide basic GFS and/or WRF training; therefore all participants are encouraged to have some knowledge of these modeling systems.

Available Spaces

There are no limits on the number of registrants for either the workshop or the tutorial lecture only option. However, due to the constraints of physical space and computers, registration for the tutorial with both lecture and practical sessions will be limited to 40 participants.

Registration & Payment

The Tutorial and the Workshop may be registered for separately. There are training fees associated with the GSI Tutorial to cover necessary material fees and other expense.

  • Tutorial (both lecture and practical sessions): $135 (includes lecture printout, lunch and refreshments for three days)
  • Tutorial Lecture only (no practical session): $85 (lecture printout, lunch and refreshments for three days)
  • Workshop only: free (lunch pre-order option is provided)
  • For NOAA Federal employees: Since NOAA is sponsoring the facility, there are no training or materials fees. All print-outs will be provided, but lunch is not included. Lunch and refreshments (morning and afternoon) may be pre-ordered for around $25 per day.

Registration must be paid by credit card. You will receive a confirmation that you have registered, and your credit card will be charged immediately. No refunds for cancellations made after July 9, 2013.

If you have any questions or are unable to register please e-mail: zarlingo@ucar.edu.

Summary of Important Dates:

  • 9 July, 2013: Registration closes for GSI tutorial, lecture and hands-on practical session option. We recommend people who are planning to attend the hands-on practical sessions register ASAP. It is a time consuming process to get individual computer accounts for the practical sessions.
  • 9 July, 2013: Last day to receive a partial refund if you need to cancel your registration for the Tutorial. Up to and including 9 July 2013, we will refund your registration fee, less $25.00 to cover administrative fees. After this date, there will be no refunds.
  • 25 July, 2013: Registration closes for GSI workshop, and GSI tutorial lecture only option.
  • 5-7 August, 2013: GSI Tutorial
  • 8 August, 2013: GSI Workshop
We look forward to your attendance!

"Second trips will be at the next available times due to the shuttle being for all hotel guests. They can call for pick-ups."

Entrance Instructions

You will need to show a valid ID to the outside guard station as you walk by/drive through. NOAA employees with badges can just show their badge. Next, walk to main entrance on the front side of building. You will need to push a doorbell and announce you are here to attend the GSI meetings (Tutorial/Workshop).

Once you enter the building, please DO NOT go through the security check point. The Conference Center is on your right, just before entering the security check point. It is a non-security area and open to public.

You are not permitted to enter the secure areas unless you are a NOAA employee or you have a NOAA host and have gone through appropriate paperwork for a visit. The GSI Tutorial and Workshop do not arrange such visits. Please arrange your visit accordingly, if needed.
