Registration for the Introduction to the Joint Effort for Data Assimilation Integration (JEDI) short course is now open.

The JCSDA hosted its 9th Symposium as part of the 101st Annual Meeting of the American Meteorological Society (AMS) January 9-15, 2021. The Annual Meeting was held as a completely virtual event as a result of the on-going COVID-19 pandemic. Despite the challenges presented by meeting completely online, the Meeting and the Symposium were successful.

A successful 4-week code sprint was conducted jointly by JCSDA core staff and NOAA contributors to greatly advance the capabilities of the observation component of the Joint Effort for Data Assimilation Integration (JEDI).

The 5th JEDI Academy was the first virtually hosted Academy by the JCSDA. It was conducted via Zoom the week of November 16 - 20, 2020. Typically JEDI Academies are held in person, serving as outlets for networking and face-to-face collaboration across partnering institutions and communities. According to participants, the 5th Academy was an excellent learning and networking experience despite the virtual environment.

The JCSDA is pleased to present the first public, open-source release of the Joint Effort for Data assimilation Integration (JEDI) system, JEDI-FV3 1.0.0. The JCSDA is also excited to announce release 2.4.0 of the Community Radiative Transfer Model (CRTM).

The Joint Center for Satellite Data Assimilation (JCSDA) is pleased to announce the public, open-source release of the Community Radiative Transfer Model (CRTM) version 2.4 on October 28, 2020.

The Joint Center for Satellite Data Assimilation (JCSDA) is pleased to announce the first public, open-source release of the Joint Effort for Data assimilation Integration (JEDI) system on October 28, 2020. JEDI is a community effort developed and distributed by the JCSDA, a multi-agency research center with its operations hosted by the University Corporation for Atmospheric Research (UCAR).

The JCSDA Near Real-Time (NRT) Observation Monitoring application now includes Global Navigation Satellite System Radio Occultation (GNSSRO) observations from all receiving satellites currently operational at NOAA (COSMIC-2, MetOp, KOMPSAT-5, TanDEM-X and TerraSAR-X).

Hyperspectral IR sounder data from U.S. (i.e., NASA’s AIRS and JPSS CrIS) and European (EUMETSAT’s IASI) sensors has proven to be one of the biggest observational contributors to improved model forecast skill at national and international operational Numerical Weather Prediction (NWP) centers. In October 2019, the JCSDA launched a collaboration with the Space Science and Engineering Center (SSEC) at the University of Wisconsin to support the assimilation of geostationary hyperspectral infrared data in the Joint Effort for Data assimilation Integration (JEDI) framework.

The Community Radiative Transfer Model (CRTM) allows us to make the best use of the billions of dollars spent on earth-observing satellites for operational data assimilation, calibration and validation, and post-processing applications. CRTM version 3.0 will extend the capabilities of CRTM v2.3, while maintaining backward compatibility; consequently, there will be very little operational risk to test or upgrade to CRTM v3.0.
