What is WRF Portal? -1

• A GUI front end to WRF
• Simplifies configuring and running WRF
• Monitors existing runs, giving users valuable
  feedback on how their run(s) are progressing
• Stores information in a mySQL database, making it
  easy for users to search through previous runs,
  compare runs, etc.
• Includes an imbedded version of WRF Domain Wizard
  (more on that later)
• Includes visualization capabilities
  (meteorological charts and graphsuses customized
  IDV library)
• Platform independent (e.g., Linux, Unix, Windows)

What is WRF Portal? -2

• Also A Framework
• The WRF Portal code and database was designed to
  be a generic framework that can support other
  models in the future with minimal code
  refactoring
• Currently an alpha release tested at ESRL and at
  DTC (Developmental Testbed Center)

Mixed color boxes will be partially
simplified/automated by WRF Portal in the future.

WRF Portal Technical Information

• Software is written in Java
• JRE 1.4x (or later)
• Uses Swing (JFC), JDBC, SSH-2 and SFTP
• Can be run directly from a web page (or from a
  command line
• 130 Java files, 33,000 lines of code
• mySQL 5 database
• supports flexible querying of namelists, user
  preferences, configuration info, runs, etc.
• Referential integrity support

WRF Portal Security

• mySQL database
• WRF Portal user logs in with username/password
  which grants him the limited database access
• does not store any sensitive information such as
  usernames or passwords to other computers
• database traffic sent via TCP/IP to port 3306 (or
  other port), password is encrypted
• Security can be further enhanced by using SSH
  Port forwarding to encrypt data coming and going
• WRF Portal uses SSH2 to
• connect to remote computer for reading/writing
  files
• run and monitor jobs

15
WRF Portal Future Work Maybe

• Grid enabled version
• Single sign-on
• Create a web based monitoring piece
• Using Java web services
• Ensembles
• Port WRF Portal to other models

What is WPS?

• WRF Preprocessing System (WPS)
• Developed at NCAR
• Just released with WRF V2.2 and replaces the
  previous WRF SI (standard initialization)
• WPS is Three Programs
• geogrid.exe localizes the domain defined in
  namelist.wps and creates a NetCDF output file. It
  extracts global geographical data (e.g. soil
  moisture, vegetation, albedo, etc.) and maps it
  to the domain projection.
• ungrib.exe -- decodes and extracts atmospheric
  parameters from GRIB files in order to initialize
  WRF
• metgrid.exe -- combines the meteorological data
  from ungrib with the NetCDF output from geogrid
  in order to produce a series of NetCDF files that
  are used to initialize WRF.

18
What is WRF Domain Wizard?

• Successor to the WRFSI GUI and is the graphical
  user interface for WPS.
• Note the older WRFSI GUI is not compatible with
  WPS
• Using this GUI, users
• define the region (and projection) of their
  domain on map
• define any nests
• run the WPS programs
• Can run as a standalone application (requiring no
  database connection) or from within WRF Portal
• Writes the domain information to namelist.wps, a
  standard file defined by NCAR

19
Domain Wizard Technical Info

• Software is written in Java
• JRE 1.4x (or later)
• Uses Swing (JFC) for GUI
• SSH-2 and SFTP to connect to remote computer (if
  user is not running WPS locally)
• Can be deployed either from a web page as a Java
  Web Start application or run from the command line

WRF Domain Wizard Future Work Maybe

• Visualize the WPS output files
• So users could inspect them before initializing
  WRF with them
• More user interface enhancements
• Port WRF Domain Wizard to other models
