1st CRTM User/Developer Workshop
Tuesday, 16 May 2017
in coordination with The 15th JCSDA Technical Review Meeting &
Science Workshop on Satellite Data Assimilation. Registration for this
workshop is now closed.
The development of the Community Radiative Transfer Model (CRTM)
and its subsequent improvements has created a critically important
method for NWP models to assimilate satellite measurements made under
all weather conditions. The CRTM was primarily developed by STAR and
EMC scientists with the support of the Joint Center for Satellite Data
Assimilation (JCSDA) to provide fast, accurate satellite radiance
simulations and associated Jacobian calculations under all weather and
surface conditions, CRTM supports all current operational and many
research satellite measurements, covering wavelengths ranging from the
visible through the microwave. The model has undergone substantial
improvement and expansion, since the first version released in 2004.
The CRTM has been used in the NOAA/NCEP and U.S. Navy operational data
assimilation systems and by many other JCSDA partners such as
NOAA/NESDIS/STAR, NOAA/OAR, NASA/GMAO, Naval Research Laboratory, Air
Force Weather, and within multiple university environments. Over the
past 13 years, external research groups and operational centers alike
have made essential contributions to CRTM development. A key goal of
the CRTM core team is to ensure that CRTM becomes a true community
radiative transfer model for all users.
The CRTM User/Developer workshop is designed to be a hands-on environment for all things CRTM.
Organization of the Meeting
The CRTM User/Developer workshop will be conducted on the afternoon
of May 16th over approximately 4 hours and 30 minutes (allowing for
breaks). You will probably want to bring a laptop to view the material
and take notes. Due to technical limitations of the guest WiFi, we'll
be unable to SSH into remote machines – this means that you’ll have to
take notes. [Note: an effort will be made to enable SSH access over
the guest WiFi, but don't count on it.]. You're on your own for lunch
on May 16th, but feel free to bring it into the conference room.
The 1st CRTM User/Developer Workshop co-organized with the 15th
JCSDA Technical Review Meeting & Science Workshop on Satellite Data
Assimilation will be hosted in the NCWCP building in College Park,
Maryland. This location offers convenient access to the Metro public
transit system of the Washington, DC area (College Park/Univ. of MD
Metro station, and the Metro bus). It is also within walking
distance of downtown College Park, MD.
For dining and accommodation options in College Park:
For parking, participants are invited to park in the NCWCP parking.
Note that a Government-issued ID may be required.

Specifically the half-day workshop will be broken into two sessions
in the afternoon of May 16, 2017. You are welcome and encouraged to
participate in either or both sessions!
Session 1: User Workshop
(1:00 - 3:00 p.m. ET)
- Focus on functionality, capabilities, and specific use cases of CRTM.
- User Tutorials will be provided and will be available online for later use.
- Case study walk-throughs will be used to identify common issues with running CRTM in a stand-alone mode.
- How to get what you need out of CRTM
- Information on future updates / development plans
Session 2: Developer Workshop
(3:30-5:30 p.m. ET)
- Focus on commonly developed/modified items in CRTM
- Coding standards update
- Optimizing your code
- Adjoint and Tangent Linear coding overview
- Future development plans / feedback
Please make sure to specify on your registration that you wish
to attend remotely.
