18th Annual WRF Users' Workshop: 12-16 June 2017, Boulder, CO
The annual WRF users' event will take place at the NCAR's Center Green Campus, Boulder, Colorado, on 12-16 June 2017.
Details and the agenda will be posted at a later date.
Call for Papers
The primary objectives for the Users' Workshop are to provide WRF modeling system updates, to discuss model development and issues and to present evaluations and applications of the model. Papers focusing on development and testing of model applications in all areas are especially encouraged. This year we especially seek contributions on WRF development and application in the area of ensemble forecasting.
Authors are given the option of requesting either a poster or an oral presentation; however, we strongly encourage authors to consider submissions for a poster presentation, due to time constraints for oral sessions.
To submit an abstract please go to the registration page.
Other Activities at the Workshop
WRF Lecture Series: Ensemble Forecasting, Monday, 1:30- 5PM
Four Parallel Mini-Tutorials, Friday, 8:30-10 AM: WRF-Hydro, VAPOR; 8:30 AM-12:00 PM: MPAS for WRF Users; NCL and WRF-Python
MPAS for WRF Users (8:30 - 12:00)
This session will provide an introduction to the MPAS-Atmosphere modeling system aimed at those who have experience running the WRF modeling system. The primary goal is to provide a complete, end-to-end explanation of the practical aspects of using MPAS-Atmosphere, and topics to be covered will include the creation of initial conditions on variable-resolution meshes, configuration of the model, and working with native model output. The use of MPAS-Atmosphere output as initial and boundary conditions for WRF will also be covered. Where possible, parallels with the WRF modeling system will be highlighted.
Analyzing and visualizing WRF-ARW data using NCL ( 8:30-10:00)
This tutorial introduces the use of NCL to read, analyze and visualize WRF-ARW data. The focus will be on how to query WRF output files and read variables, how to calculate various WRF diagnostics, and how to create nice 2D visualizations. We will provide some template NCL scripts that you can use on your own WRF-ARW data. For those with an interest in Python, be sure to check out the wrf-python tutorial that immediately follows this one.
Analyzing and visualizing WRF-ARW data using wrf-python and other Python tools (10:30-12:00 Noon)
This tutorial introduces the wrf-python module, a full Python implementation of the WRF-NCL diagnostics package. This package was first released in early 2017 and is developed by the same team that develops NCL. This tutorial will include a brief introduction to using conda for installing Python packages, and Jupyter Notebook for editing and running Python scripts. The focus will be on using wrf-python to calculate a variety of WRF diagnostics, but we will also demonstrate using Python packages like PyNIO and netcdf4-python for reading WRF-ARW files, and cartopy and matplotlib for creating simple 2D visualizations.
WRF-Hydro (8:30 - 10:00)
The WRF-Hydro mini-tutorial will go over basic model description of the WRF-Hydro system, its implementation process and a few summary applications of the model. A basic introduction to some of the model pre- and post-processing tools will also be presented.
VAPOR is an application developed by NCAR for 3D scientific data visualization. It is free to use, open source, and runs on OSX, Windows, and Linux.
In this session, users will be given an interactive tutorial on how to use VAPOR to produce 3D images and movies from WRF data. VAPOR contains a set of renderers that can be used to demonstrate various weather features. This tutorial will interactively demonstrate to users how these renderers can be used to visually explore the regions and features of interest within model data, and how to depict these regions in an aesthetically pleasing and scientifically publishable way.
Please click here or go to the registration page to register for the workshop and submit papers.
During the workshop, the WRF helpdesk will be open for several sessions for users to discuss their special issues with developers.
Abstract submission is 17th April, 2017
Last date to make changes to abstracts: 22 May, 2017* (
May 17: workshop program to be posted on the web)
Early registration ends: 22 May, 2017
Late registration begins: 23 May, 2017
If you cancel your registration prior to 22 May, we will refund your registration minus $25 to cover administrative fees.
After 23 May: No refunds for cancellations
* Please note: any changes made beginning 23 May will be made online but not in the printed agenda and any abstracts submitted or changed after 23 May should be emailed to "wrfhelp at ucar dot edu".
Workshop presentations and extended abstracts will be published on our website via links provided during the workshop. (You may indicate that you do NOT want us to publish your abstract when you submit it). Extended abstracts in PDF format can be submitted via the registration page, and will appear on the web before the workshop.
We would like to encourage all poster presenters to provide us with an electronic (preferably .pdf format) version of their posters (or a short .pdf file describing the poster) so that we can post it on our website prior to the workshop. Please email these to "wrfhelp at ucar dot edu". If presenters are not able to submit them to us before the workshop, we will still be accepting them afterward, and we will post them upon receipt.
Workshop Registration Fees
The early registration fee is $200.00. If you register on or after 23 May, the registration fee will be $250.00.
Blocks of hotel rooms have been reserved at three different Boulder hotels. Please click on the "Lodging" Tab at the top of our website for details.
