15th Annual JCSDA Science Workshop

17-19 May 2017 The 15th Annual JCSDA Science Workshop was held May 17-19, 2017, in College Park, MD, at the NOAA Center for Weather and Climate Prediction. This event provided a forum for scientists associated with all of the JCSDA partner institutions and the external research community to share the latest developments in satellite data assimilation, particularly as these relate to the status of JCSDA priorities and projects. More than 70 registered participants contributed to the three- day event composed of eight oral sessions, two poster sessions, and a multitude of informal discussions. Numerous local "walk-ins" took advantage of the opportunity to participate as well.

Representing the Management Oversight Board (MOB), Dr. Steven Pawson of NASA opened the workshop, emphasizing the MOB's confidence that the new JCSDA management structure will lead to more effective collaboration and progress. Dr. Thomas Auligné then described that structure in detail and explained how JCSDA projects are organized and executed within it. To conclude the morning sessions, members of the JCSDA Executive Team made presentations on the status of contributions from the individual JCSDA partner institutions toward state-of-the-art satellite data assimilation.

Wednesday sessions covered atmospheric composition, assimilation of aerosol data, and improvements to data assimilation systems, highlighted by an overview of the new Joint Environment for Data-assimilation Integration (JEDI) project. A lively poster session followed.

Thursday sessions featured the Community Radiative Transfer Model (CRTM), including talks devoted to progress with microwave scattering for snow and graupel and efforts supporting specific sensor calibration and validation, and computational improvements for accuracy and speed. Further topics included sensor- specific DA, with emphasis on using microwave sounding data in operational hurricane and mesoscale modeling systems, as well as to the assimilation of GPSRO data from a growing variety of sources including COSMIC-2 and commercial pilot weatherdata observations.

Friday morning opened with a series of talks on observing system assessment and optimization. The final session featured presentations addressing the assimilation of observations impacted by clouds and precipitation. The formal proceedings were closed with remarks from the NESDIS/STAR Director, Harry Cikanek, who encouraged the participants to build on the work already done and take advantage of the new project management to accelerate exploitation of satellite data in the nation's operational forecast systems.

First CRTM User and Developer Workshop

First CRTM User and Developer Workshop

16 May 2017 - The First Community Radiative Transfer Model (CRTM) User and Developer Workshop took place May 16 at the National Center for Weather and Climate Prediction Center (NCWCP) in College Park, MD. This half-day event was intended as the first in an annual series of workshops on all things CRTM.

The workshop was divided into two sections, covering both use and development of CRTM. In the user section, 27 in-person participants came from a broad range of academia, operational centers, and federal research facilities all around the country. An additional 10 people participated online. The following topics were introduced through a series of 20- to 25- minute presentations/tutorials.

The second half of the workshop was aimed at CRTM developers, with a specific focus on improving its underlying scientific and technical basis as well as providing background on tools used to develop and release CRTM. This part of the workshop was attended by 40 people, with approximately 10 online participants. During the workshop, we identified several key goals for the future of CRTM: focusing on improving scientific accuracy and capabilities, performance optimizations, the development of user and developer toolsets, documentation and tutorial creation, and improved developer interaction with the CRTM team.

For the next CRTM User Developer Workshop we plan to create a series of tutorials to let attendees work through common use cases and allow developers to work with experts to learn how to modify and update CRTM in a consistent fashion. By this time, we also expect to have released a series of toolsets that enable users and developers to get the most out of CRTM. The CRTM team and the JCSDA would like to thank all the participants and tutors who made this workshop a success. If you'd like to keep up with regular developments of the CRTM, e-mail to join the bi-weekly CRTM teleconference, where we discuss a wide range of scientific and technical issues.
