Earlier this month JCSDA’s Cheng Dang joined Bill Kuo, UCP Director, and Mohan Ramamurthy, Director of EODS Center and Unidata, on a four day visit to Utah State University and the University of Utah. Along with presentations and seminars about JCSDA for the students, they met with faculty using JEDI and data assimilation in their own research.

In quarter four Eric Lingerfelt, Evan Parker, and Dom Heinzeller from the JCSDA core team and Tariq Hamzey from NASA GMAO met in Boulder for a code sprint to redesign R2D2 into a scalable, flexible client/server system.

JCSDA is pleased to announce the release of Skylab 8.0!

JCSDA SkyLab 8.0 is the eighth  roll-up release that provides integrated Earth System Data Assimilation capability.

On Thursday, January 25, the JCSDA core team and partners from NOAA, NASA, U.S. Navy and Air Force, and the UK Met Office met virtually and in-person to review accomplishments from the last three months and discuss future goals. This quarter saw a lot  of functionality added to SkyLab with the release of SkyLab v7, two spack-stack releases, numerous additional  sensors, and much more!

The JCSDA is pleased to announce the release of Skylab 7.0!

JCSDA SkyLab 7.0 is the seventh roll-up release that provides integrated Earth System Data Assimilation capability. All JEDI code is open source and publicly available at https://github.com/JCSDA. Capabilities are demonstrated via the SkyLab testbed experiments conducted internally at JCSDA for the following components

We are pleased to announce the 20th JCSDA Technical Review Meeting and Science Workshop will be held at UCAR's Center Green facility in Boulder Colorado on May 14-17, 2024. The theme for this year is Earth System Data Assimilation, with representation from various communities

The first phase of transitioning the NASA GMAO GEOS atmospheric data assimilation capabilities to JEDI involves the replacement of the Grid-point Statistical Interpolation (GSI) with a corresponding JEDI analysis. This includes taking JEDI's Unified Observation Operator (UFO), its underlying dependencies, and the JEDI solver that enables a hybrid 4DEnVar strategy similar to what is used in the current GEOS-GSI system.

2023 was a great year for JCSDA, with three Skylab releases, 8 spack-stack releases, and big steps towards operations. Our biggest highlights:

The JCSDA team came from across the country to meet in Boulder, Colorado, in the last week of October, renewing cross-team ties and planning for the JEDI-Skylab developments ahead.

On Thursday, October 26, the JCSDA core team and partners at NOAA, NASA, U.S. Navy and Air Force, and the UK Met Office met virtually and in-person to go over accomplishments from the last three months and discuss future goals. Exciting milestones include two partners passing thresholds for JEDI operations and spack-stack 1.5.0 being officially put into use by UFS!

On the 26th to the 28th of September, 2023, the International Earth Surface Working Group (IESWG) convened a hybrid meeting with the in-person component at the Finnish Meteorological Institute in Helsinki, Finland. JCSDA’s Dr. Benjamin Ruston co-chaired and facilitated the running of the meeting.

The JCSDA is pleased to announce the release of Skylab 6.0!

JCSDA SkyLab 6.0 is the sixth roll-up release that provides integrated Earth System Data Assimilation capability.

In 2021, JCSDA and NOAA EMC began exploring Spack as an option for creating a single software stack that could be used for both the JEDI DA software environment and the Unified Forecast System (UFS) ecosystem. Since then both teams have combined their efforts to put together a new stack that works with not only JEDI and the UFS, but also with MPAS, NEPTUNE, the Unified Model and soon GEO.

Last week three members of the JCSDA staff—Dr. Shih-Wei Wei, Dr. Sarah Lu and Dr. Maryam Abdi-Oskouei—attended the 2023 Meteorology and Climate-Modeling for Air Quality Conference, or MAC-MAQ, at UC Davis in Davis, California.

Last week a combined JCSDA team from the core staff, NOAA, NASA, and the UK Met Office conducted a code sprint for Variational Bias Correction (VarBC) in JEDI’s Unified Forward Operator (UFO).  The code sprint worked towards adding the ability to apply bias correction to observations by record, like those from aircraft and ships, in addition to channels.

At NASA’s Global Modeling and Assimilation Office (GMAO) weather prediction is as much an operational endeavor as a research one, with a NWP model run daily that produces forecasts for NASA customers and missions. The team that designs and runs that model is one of JCSDA’s integral partners, both providing input and putting JCSDA innovations like the JEDI unified data assimilation framework into operational practice.

When Dr. Michael Morgan opened the UIFCW Conference on July 24, 2023, he focused his remarks on not just data assimilation but the work being done with JEDI by JCSDA and partners, recognizing that work as a key part of the future of forecast models.

On Thursday, July 13, the JCSDA core team and partners at NOAA, NASA, the Navy and the Air Force met virtually and in-person to go over accomplishments from the last quarter and discuss future goals.

The JCSDA is pleased to announce the release of Skylab 5.0!

JCSDA SkyLab 5.0 is the fifth roll-up release that provides integrated Earth System Data Assimilation capability via a unified end-to-end ecosystem including a single code build, workflow, data store, and diagnostics dashboard.
