Joint Center for Satellite Data Assimilation

What Joint Center for Satellite Data Assimilation does

The Joint Center for Satellite Data Assimilation (JCSDA) is a US federally chartered multi-agency research center established in 2001 by NASA and NOAA and hosted by the University Corporation for Atmospheric Research (UCAR) and UCAR Community Programs (UCP) in Boulder, Colorado. It is dedicated to accelerating and improving the quantitative use of research and operational satellite data in weather, ocean, and environmental analysis and prediction systems. Founded to address a two-year lag between satellite launch and operational use of sensor data — a lag JCSDA reports reducing to one year, a 33% improvement — the center builds shared, open-source infrastructure so that the work required to use billions of daily satellite observations is distributed across agencies rather than duplicated.

JCSDA's primary technical product is JEDI (Joint Effort for Data assimilation Integration), a unified, model-agnostic data assimilation framework written in C++ with Fortran computational kernels. JEDI integrates specialized subsystems: OOPS (object-oriented prediction framework), IODA (observation data interface), UFO (unified forward operators), SABER and BUMP (background error covariance modeling), and the CRTM (Community Radiative Transfer Model). It interfaces with multiple earth-system models including FV3 (used by NOAA's Unified Forecast System), MPAS, and the SOCA ocean assimilation component. Skylab serves as an integrated testbed bundling JEDI components and model interfaces into periodic roll-up releases (most recently JEDI 2026.1 and SkyLab 8.0). All software is open source and distributed through public GitHub repositories, with optional Spack-Stack packaging supporting 14 HPC platforms and AWS cloud.

JCSDA does not sell commercial products or services; it is funded through interagency agreements with NASA, NOAA, the US Navy, and the US Air Force, supplemented by grants such as a 2019 NOAA Disaster Relief Appropriations Supplemental award. Operational and research partners include the UK Met Office as an international collaborator. Distribution and community engagement occur via open-source self-serve (GitHub), JEDI Academies (week-long training workshops), quarterly newsletters, public forums, technical review meetings, and collaborative code sprints with partner agencies and academia. The center has 12 core staff but operates as a distributed collaborative effort leveraging personnel and computing resources across its partner agencies.

Core offering

JCSDA develops and distributes the open-source JEDI (Joint Effort for Data assimilation Integration) framework, an integrated Earth System Data Assimilation software stack for assimilating satellite observations into numerical weather, ocean, and environmental prediction models. It also provides the CRTM radiative transfer model and the SkyLab integrated testbed, all released openly via GitHub to federal agencies (NASA, NOAA, US Navy, US Air Force), the UK Met Office, and the broader scientific community, with no commercial sale or licensing of the software.

Product overview

JCSDA is a multi-agency research center that develops JEDI, a unified open-source data assimilation framework for earth system prediction. The JEDI system integrates multiple specialized components: the OOPS framework provides the core architectural foundation; UFO handles observation operators and quality control; IODA standardizes observation data formats; BUMP and SABER manage background error covariances; CRTM performs radiative transfer calculations. JEDI interfaces with multiple earth system models including FV3 (for operational weather forecasting), MPAS (for atmospheric prediction across scales), and SOCA (for ocean data assimilation). SkyLab serves as the integrated testbed demonstrating these capabilities. The software is open-source and available via GitHub, with releases like JEDI 2026.1 and SkyLab 8.0 marking major version milestones.
