Tutorial Overview

The Weather Research and Forecasting (WRF) model tutorial will be offered during a two week period from 21 July - 1 August 2014 at the NCAR Foothills Laboratory, Boulder, Colorado.

The tutorial will be divided into 4 sessions. Participants can attend any combination of these sessions. Please note that the optional WRFDA practical session scheduled for Wednesday morning (30 July) overlaps with the first half of the Regional Climate Tutorial. You can sign up for both, which means you will have to skip the optional WRFDA practical session.

1. Basic WRF Tutorial (21-25 July 2014) The tutorial will consist of lectures on various components of the WRF modeling system along with hands-on practice sessions. The topics include:

a. WRF Pre-processing System
b. WRF Dynamics and Numerics
c. WRF Physics
d. Software Framework
e. Post-processing and Graphical Tools
f. Introduction to WRF-fire, WRF-Hydro

2. WRFDA Tutorial (28-30 July 2014) A WRF-ARW-only data assimilation tutorial (including hands-on practice) will be offered for 2 and a half days during the second week of the tutorial. The topics will include:

a. Compiling WRFDA for 3DVAR/4DVAR
b. Converting and assimilating conventional data using OBSPROC
c. Assimilating radiance data using RTM
d. Background error estimation using GEN_BE
e.Hybrid variational/ensemble assimilation
f. Analysis/forecast verification

Users may attend this tutorial without attending the basic WRF tutorial; however, a basic understanding of the WRF model is required to make full use of the WRFDA tutorial.

3. WRF Regional Climate Tutorial (30 July 2014) This tutorial provides a broad overview of the use of the WRF model as a regional climate model. Topics that will be discussed during this day session will include:

a. Model design, including guiding principles for selection of domain size and location and grid spacing
b. Input data, including handling of bias in global model data
c. Traps and good practice for regional climate simulations
d. Sources of uncertainty in regional climate simulations
e. Statistical downscaling of regional climate and extreme events
f. Application of Bayseian techniques as a regional climate downscaling tool

4. WRF Chem Tutorial (31 July - 1 August 2014) A WRF-ARW-only chemistry tutorial will be offered for 2 days during the second week of the tutorial. Topics include:

a. General overview of WRF Chemistry
b. Chemistry options
c. Using chemical sources in simulations

Users may attend this tutorial without attending the basic WRF tutorial; however, a basic understanding of the WRF model is required in order to make full use of the WRF-Chem tutorial.

Requirements

Basic knowledge of atmospheric science and numerical modeling, as well as working in a Unix computer environment, is required for the class. Basic WRF Tutorial participants are strongly encouraged to work through the WRF-ARW online tutorial, especially if you have not used the model before. Walking through the online tutorial will provide an overiew of the system, which can help enhance your learning experience once you are here (even if you cannot compile and run the code physically). Additional information about WRFDA can be found here and additional information about WRF Chemistry can be found here.

All participants are also strongly encouraged to get familiar with Unix/Linux working environment, as working through directories, editing text files and Fortran code are absolutely essential to operate the modeling system programs. One can easily find unix tutorial for beginners online for this purpose.

Available Spaces

Due to the constraints of physical space and computers, we can only accommodate a maximum of 60 participants for the WRF Basic tutorial, 40 for WRFDA, 40 for WRF Chem, and 60 participants for the Regional Climate Tutorial.

Register early, as registration always exceeds capacity! After these seats have been filled, a wait list will be established and the status will remain as pending until a seat becomes available.

Registration & Payment

The registration fees are as follows:

(1) All Universities, U.S. Government & NCAR/UCAR

Basic $450 (All Universities and U.S. Government)
Basic $430 (NCAR/UCAR)

DA $250
Regional Climate $100

Payments are due by 2 June 2014 and there will be no refunds for cancellations made after 6 July 2014.

Upon registering, you will receive an email acknowledging that we have received your registration application. At this point your registration will be "pending." Once we have received your application and we still have seats available you will receive an email stating you have been accepted, at which time your credit card will be charged. We will not charge your credit card until you are accepted.

If you have any questions or are unable to register please e-mail: workshop@ucar.edu. Please see the Registration & Payment Page for more details.
