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
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.
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!
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.
